Seagram Building

In 1954, Samual Bronfman, Chairman of the board of Joseph Seagram and Sons, decided to construct a “building of fine quality” to house the company’s head office in New York City. The construction of their new corporate headquarters signaled the evolution of the Seagram Company from family-owned manufacturers of “branded” consumer products to a diversified multinational corporation. The Seagram Building was the first in a series of high-rise curtain wall monoliths that were erected on Park Avenue following construction of Lever House in 1952 that transformed Park Avenue into a monument to the International Style. The Seagram Building represents the felicitous convergence of art and commerce. It combines themes that had preoccupied Mies van der Rohe since the 1920s with the modern business and marketing requirements of his client.
Samual Bronfman had expressed little enthusiasm for modernist architecture. Morris Lapidus had designed the Seagram Company’s first New York City offices in the Chrysler Building in “a Tudor style, complete with fake fumed fireplaces and pegged linen-fold oak panels.” Charles Luckman of the California architectural firm Luckman and Pereira (and president of Lever Brothers) created the initial blueprints for  the Seagram Building, which called for a massive structure in the “set-back,” or “wedding-cake” style prescribed by zoning laws and prevailing taste. An article about Luckman’s proposal in the “New Yorker” prompted Phyllis Lambert (Samual Bronfman’s daughter) to return to New York from Paris in an effort to persuade her father to select another architect. He put her in charge of the selection process.  After  rejecting Frank Lloyd Wright (“His is not the statement needed now.”) and le Corbusier (“One is fascinated by his spaces, his sculptural forms, but are not people likely to be blinded by these and skip over the  surface only.”),  a committee that included Philip Johnson recommended Mies van der Rohe (“Mies forces  you in. You have to go deeper”), “despite Father’s edict ‘no stilts.’”
The 1916 ordinance was still in place in 1954. Mies’s first challenge was zoning compliance: “On the Seagram Building, since it was to be built in New York and since it was to be the first major office which I was to build, I asked for two types of advice for the development of the plans. One, the best real estate advice as to the types of desirable rentable space and, two, professional advice regarding the New York Building Code.” Rather than making maximum use of the zoning “envelope,” Mies restricted his building to one quarter of its site, rejecting “setbacks” in favor of a monolithic tower. The building is set back 100 feet from the sidewalk, creating a public plaza with twin fountains. The Seagram Building ”indulges in the luxury of empty space”. Real estate consultants determined the building’s volume by combining the area required by the Seagram Company with a figure considered optimally marketable to leaseholders (the building contained offices in units as small as 500 square feet). The total they arrived at was well below that permitted by the New York City Building Code.
The advent of steel-frame construction and the elevator at the end of the nineteenth century had made the construction of buildings of seemingly unlimited height and bulk feasible. In 1900, Cass Gilbert described the skyscraper as “a machine that makes the land pay.” For George Hill “An office building’s  prime and only object is to earn the greatest possible return for its owners, which means that it must present the maximum of rentable space possible on the lot, with every portion of it fully lit.” Opposition to the unregulated construction of skyscrapers in New York emerged early in the twentieth century, and a limit on building heights was promoted by citizens and government officials concerned about the degradation of the city’s infrastructure. Progressive reformers expressed concern about the aesthetic deterioration of the city and the immorality of the huge profits generated by such development. Ultimately, the real estate industry itself, in an effort to stabilize the market, brought about the revision to the zoning law effected in 1916 that restricted for the first time the height and bulk of new construction.
               
The plaza had other consequences. It removed the building from  its  surrounding  context, creating a vantage point from which it could be contemplated as an autonomous object, and from which neighboring buildings could be viewed. The Bronfmann family, like the owners of Lever House, eschewed lucrative street level commercial enterprises. In fact, Gordon Bunshaft, designer of Lever House, tried unsuccessfully to persuade his client to include commercial properties in the ground floor of his design.    Two restaurants, designed by Philip Johnson, are located under the plinth, and have discrete entrances. Automobile parking, linking the building to its corollary suburban developments, is also concealed beneath the plinth. The way that the restaurants and parking facilities are incorporated into the overall scheme demonstrates the extent to which form and function conflict.  An important element of visible human  activity has been eliminated by the concealed parking facilities.  Visitors go directly from the parking   garage to the interior elevators. A low wing overlooking the plaza accommodates the Four Seasons Restaurant, restoring some of this visible activity to the building. Evidence of urban infrastructure is also suppressed. Traffic signals are situated on the median that runs down the center of Park Avenue; there are no pedestrian crossing signals.  Commercial traffic is prohibited on Park Avenue, and there are no public  bus stops or subway station entrances.
Mies’s ambition was to create a work of art, and his success has tended to be judged by the  extent to which the Seagram Building achieves a universal aesthetic ideal by suppressing whatever is programmatically incompatible with its monumentality: “the Seagram Building is a monument to an idea first and to a corporation second.” Classical resonances, manifest in its Palladian symmetry and mathematical regularity, are invariably invoked in descriptions of the Seagram Building. “The striation of all the columns can be read as an abstract form of fluting, and the three steps leading from the sidewalk to   the plaza act as a modernist adaptation of the classical temple stereobate.” It engages in a dialogue with  the classicism of the Racquet and Tennis Club across Park Avenue by McKim, Mead and White, “a neo-Florentine palazzo”. The opulence of building materials and quality of construction reinforce the Seagram Building’s stature as a work of art. “The foyer features four ranks of elevators clad in quality travertine.” The exterior vertical I-beams are bronze. The Seagram Building is almost invariably photographed from the north, removing it from the context of its International Style simulacra.
Mies frequently subordinated function to aesthetic considerations. The compressed profile of the slab makes the offices on the upper floors small and cramped, and circulation inefficient. Phyllis Lambert describes the complications posed by the “intrusion” of the elevators: “They determine your bay system (in a columnar building a bay is the area between columns), the height of your building and heaven only   knows what else. On the first try X. called me up-disaster-no building just elevators. Now all is getting in order-the Otis people are constantly consulted and asked to do their most brilliant best-but no matter what you do the elevators take up three bays!” (The role that the elevator has played in the evolution of New  York City’s infrastructure is remarkable. Automatic elevators, which eliminated the expense of hiring operators, made the ubiquitous six-story apartment house possible.)  The glass and aluminum envelope   has little thermal and auditory insulation.
On the other hand, Mies embraced technology. The Seagram Building reflects his long-standing interest in new techniques and materials. Indeed, the “rationalization” of construction technique, which in practice took the form of a modular system, was a premise of his architecture. Curtain wall construction reduced the cost of construction of the Seagram Building by ten percent over conventional frame-and-infill methods (before the lavish materials are taken into account). The module is more than a matter of utility. The module freed Mies’s architecture from the “straitjacket of historical style imitation.” Based on a grid,  the module valorizes the lateral, as opposed to hierarchical, disposition of space: “The modular system  tends to abolish the center” It is also the “outward sign of a new order.” Even so, Mies upped the stakes by basing the design of the Seagram Building on a nonstandard 4 ft 7-1/2” module. Artistic intention and rationalized methodology reinforce each other.
Mies embraced glass as a building material in the 1920s: “The novel constructive principle of  these buildings comes clearly into view if one employs glass for the no longer load-bearing exterior walls. The use of glass, however, necessitates new approaches. In my design for the skyscraper at the Friedrichstrasse railroad station in Berlin, intended for a triangular site, a prismatic form corresponding to the triangle appeared to offer the right solution for this building, and I angled the respective façade fronts slightly toward each other to avoid the danger of an effect of lifelessness that often occurs if one employs large glass panels.  My experiments with a glass model helped me along the way and I soon recognized   that by employing glass, it is not an effect of light and shadow one wants to achieve but a rich interplay of light reflections.” Mies equates the transparency that illuminates the interior (this project predates fluorescent lighting), at least from a vantage point outside the building, with “lifelessness.” The reflective properties of glass animate the building’s exterior. “At first glance the contour of the ground plan appears arbitrary, but in reality it is the result of many experiments on the glass model. The curves  were determined by the need to illuminate the interior, the effect of the building mass in the urban context, and finally the play of the desired light reflection.” Brown-tinted glass installed in the facade of the Seagram Building reflects neighboring buildings.Seagram Building
In 1954 Samual Bronfman, Chairman of the board of Joseph Seagram and Sons, decided to construct a “building of fine quality” to house the company’s head office in New York City. The construction of their new corporate headquarters signaled the evolution of the Seagram Company from family-owned manufacturers of “branded” consumer products to a diversified multinational corporation. The Seagram Building was the first in a series of high-rise curtain wall monoliths that were erected on Park Avenue following construction of Lever House in 1952 that transformed Park Avenue into a monument to the International Style. The Seagram Building represents the felicitous convergence of art and commerce. It combines themes that had preoccupied Mies van der Rohe since the 1920s with the modern business and marketing requirements of his client.

Construction of its new corporate headquarters generated tremendous publicity for the Seagram Company. Articles about the building appeared in academic and popular journals and periodicals. Mies’s dictum “less is more” adorned an article in Time Magazine in 1958. The  building’s  completion  also coincided with dramatic changes within the Seagram Company. Sales were slipping. “The top group was getting older. General Schwengel, the figurehead president of Joseph E. Seagram & Sons Inc., was in his seventies, as was Jim Friel just before his death. Bill Wachtel, the head of Calvert, was in his late sixties, and on and on.”  Their ignorance of modern marketing techniques had made the old guard expendable.  “Part of the problem was that Father and Seagram were far behind the new marketing curve.” Edgar Bronfman, chairman of the administrative committee, urged his father Samual to oust Schwengel and appoint him president of the company. His father complied. After his appointment, Edgar launched a much-publicized campaign to revive a failing product, “Calvert Reserve” whiskey, in “order to prove to my own organization, to the distributors and retailers, and to the industry that I was qualified to run the company.” He demonstrated his awareness of the marketing potential of absence and superfluity by repackaging “Calvert Reserve” as “Calvert Extra,” and replacing every unsold bottle of “Calvert Reserve” in every retail store in the country with a bottle the “new” product.
In another statement (paraphrasing a Catholic theologian and philosopher named Romano Guardini under whose spell Mies had fallen) that invokes the epiphany of Christian mysticism,  Mies conflates technology with transparency, and transparency with truth: “Nothing seems impossible anymore. Thus begins the reign of technology. Everything succumbs to its impact. It detaches man from his restrictions, makes him freer and becomes his great helper, breaks down the isolation of geographical locations and bridges the largest distances. The world shrinks more and more, becomes surveyable and is investigated down to its remotest recesses. The characteristics of peoples become clear. Their social and economic structures are uncovered. World consciousness and a conscious awareness of mankind results. Technology offers a thousand means to increase awareness. Nothing occurs anymore that is not observed. We survey ourselves and the world in which we stand. Consciousness is our very attitude.”
Media representations of urban corporate life were prevalent in the 1950s and 60s. A cinematic genre featuring New York  City corporate protagonists, frequently advertising executives, who commute  form suburban homes to midtown office towers, emerged.  Ranging from portentous statements such as  The Man in  the  Gray  Flannel  Suit  (1956),  directed  by  Nunnelly  Johnson  (primarily  a  screenwriter  and infrequent director), The Apartment (1960) directed by Billy Wilder, and Breakfast at Tiffany's, (Blake Edwards) to banal “knockoffs” such as Lover Come Back (1961), starring Rock Hudson and  Doris  Day, these films project both dreadful and  auspicious  images  of  corporate  architecture.  Protocols  that  govern relationships between the sexes and between  employers  and  employees  are  common  themes    in these films. In The Apartment,  the  corporation  is  depicted  as  a  predatory  patriarchy.  In  Lover Come Back it becomes a benign site for a coy “battle of the sexes” between  two  corporate  executives.  The fascination of these films may reflect what  Rem  Koolhaas  calls  Automonumentality.  The  architectural grid is not generated infinitely from a single point in space, but begins at the periphery of a habitable spatial configuration, extending inward and outward. In a sense, two approaches to architecture exist; one emphasizes the disposition of exterior  configuration  over  interior  functionality,  while  the  other reverses these priorities. Conceived on a grand enough scale, the connection between exterior and interior dissolves, resulting in a break or “surgical severance” between an “honest” façade  and  the activities it conceals. “In the deliberate discrepancy between container and contained New York’s makers discover an area of unprecedented freedom.”
The celebrity of the Seagram Building had unanticipated consequences.   In 1963, the New     York City Commission imposed a “prestige” tax on the Seagram Building, inciting a public outcry that culminated in an article by Ada Louise Huxtable called “Another Chapter in How to Kill a City” published      in the New York Times on May 21, 1963. The standard tax rate  was  “based  on  a  building’s  ‘market value’, a  figure  reached on the basis of net income, capitalized at a customary 6 per cent plus 2 percent  for depreciation. By this formula, the Seagram Building comes up with a figure that hovers roughly around
$17,000,000.  It is no secret that this extravagantly beautiful edifice cost $36,000,000 to build.   And   there, as  anyone  can  clearly see, is more than another $17.000,000 in untapped taxes in a city starved  for revenue.” The State Appellate Division of the State Supreme Court ultimately established a drastically increased tax assessment policy for “prestige” buildings based on construction cost.
The Seagram Building was also the impetus for the  first  revision  to  the  New  York  City  Building Code since 1916. At a symposium in 1992 called “Planning and  Zoning  New  York  City:  Yesterday, Today, and Tomorrow” Sigurd Grava, Robert Stern, Frances Halsband, Carol Willis, Jerold Kayden, Roy Strickland, Norman Marcus, and Richard A. Plunz discussed the implications of  the  new  Zoning Ordinance. (At this symposium, Robert Stern memorably remarked that “planning is much too important to be  left  to  the  planners.”)  The  following  exchange  underlines  the  impact  of  the  Seagram Building on contemporary architecture. “Stern:  ‘The  1961  resolution,  I  am  embarrassed  to say, was  pushed  through  basically  by  architects who had an absolute idee fixe about what the city  should be like.’ Kayden: ‘And the Seagram Building was literally the aesthetic model for that.’”
The new ordinance established the first finite limits on volume (and therefore on height) thus reducing not only bulk of buildings but, by extension, the overall density of the city.  “Like Chicago, it did   so by establishing a FAR (floor to area ratio) formula, eliminating the open-ended  provision  for  unrestricted  height over one quarter of the lot.  A simple idea with a handbook of variations, FAR keyed   the amount of floor space permitted in a building to the area of its lot.   The highest basic FAR was     fifteen.  This could be increased twenty percent to an FAR of eighteen, if a developer included a public   plaza  or  arcade.  Such  “incentive  zoning”  was  designed  to  create  more  open  space  at  street   level in  the  city’s  most  densely-populated districts.   The new ordinance encouraged tower-in-the-   plaza schemes by increasing the area of coverage of towers from twenty-five to forty percent of the lot. Thus the FAR formula effectively ended the standard setback massing, not because the new  code  prohibited it, but because sheer-walled towers in open plazas became more profitable.”
In fact, real estate developers opposed the new ordinance, and rushed to construction an enormous number of  projects  before  it  took  effect.  Robert  Stern  attributes  the  reconstruction  of  Park  Avenue to the 1961 zoning law.   The new law also intentionally, though indirectly, imposed limits     on the city’s population. In introducing the proposed  revision,  James  Felt,  the  chairman  of  the  New York City Planning Commission, included as a “fundamental  principle  of  good  zoning”  a  population ceiling of eleven million people, considerably fewer than the fifty-five million that the 1916 law hypothetically permitted.
An unexpected side effect of the 1961 zoning revision was a precipitous increase in street crime. Public attitudes toward new privately owned public open spaces began to reflect the new danger they represented. An influential book by Oscar Newman called Defensible Space responded to the new public fears and began to influence property owners as well as planners. Illegal grills and fences were erected to protect open spaces at off-hours. Spikes were  installed  on  surfaces,  on  which  people  might  sit  or sleep. Planners and urban designers devised a new bonus: a project  that  included  shop-lined  and  covered public spaces received extra density.
The Seagram Building created a sensation when it was completed in 1958. Intended as a monument to Samual Bronfman, its presence in New York City has had profound legal, aesthetic, civic,    and media repercussions.   It has been designated as a landmark, and it continues to inspire architects.   The  Seagram Company continues to grow and diversify its operations by purchasing media companies   such as Universal Studios and Polygram Records.

 
Optical Correction

Many people assume that Vitruvius’s theory of architecture is rigidly prescriptive, and that architecture during the Renaissance followed a trajectory defined by an increasingly liberal attitude to strictly codified ancient canons. The following passage from the Ten Books on Architecture indicates that Vitruvius endorsed improvisation: “In fact, Hermogenes, once he had already acquired a supply of marble to complete a Doric temple, changed his mind and made this temple an Ionic shrine to Father Liber. He did not do this because the species and the type of Doric are unattractive, or because it lacks dignity of form, but because git is restrictive and inconvenient in working out the distribution of triglyphs and the spaces between them.”1 Examining Vitruvius’s ideas about optical correction further complicates the assumption. Vitruvius had recommended adjustments to correct the distortion of dimensions that occurred when buildings were viewed from different vantage points. Renaissance theorists had invoked optical correction to justify discrepancies between proportions stipulated by Vitruvius and archaeological evidence. Renaissance architects such as Leonardo da Vinci and Sebastiano Serlio, among others, attempted to quantify aspects of optical correction that had been ad hoc, ambiguous, or lost in Vitruvius’s own writings, leading to a controversy that culminated in Claude Perrault’s rejection of optical correction, the instrumentalization of proportion in the seventeenth century, and the diminishing importance of Vitruvian theory.
The fact that a marginal aspect of Vitruvius’ theory incited Perrault’s critique warrants examination, and can be explained in part by the intersection of architecture and science in Renaissance treatises, and the vulnerability of optics to scientific inquiry. Vitruvius’s description of optical refinements is contained in Books Three and Four of his Ten Books on Architecture as part of a general discussion of proportion, particularly as it relates to the design of sacred buildings. Vitruvian proportion had two components; one was a scientific or quasi-scientific theory of the physics of light and optics derived in part from Euclidian geometry, and the other was symbolic and derived from the human body. Renaissance translations of Vitruvius and independent architectural treatises tended to segregate these components and to valorize one over the other. Vitruvius’s origin narratives make explicit the connection between columns and the human body, although the relationship between the Doric and Ionian columns retained only their (geometric) proportional relationship. Thus, entasis, which means tension, straining, exertion and can refer to the human body, defines the shape of columns. Vitruvius uses it to describe the slight outward curvature in the silhouette of the Doric shaft.2   Leon Battista Alberti’s own narrative in On the Art of Building in Ten Books reduces origin narratives to a “shadowy but unmistakable presence,”3 whereas Cesare Cesariano restores them to prominence in his Italian translation of Ten Books on Architecture.4 The connection between figuration and columns recurs in Renaissance translations. Sebastiano Serlio combines rustic motifs with bound figures in his Extraordinary Book, but this section is appended to his Tutte l’opere d’architettura et prospectiva is appende, far from his treatment of geometry and optics.
Ingrid Rowland suggests that Vitruvius was aware of a tradition of scientific optics, which was both physical (the viscosity of air as optical disturbance) and geometric (vision as pyramidal or conic rays or vectors). He was aware of a debate as to whether vision is the result of the impact of images emitted by the object, or of visual rays shed from the eyes.5 This controversy informed the optical theories of such diverse figures as Leonardo da Vinci, Alberti, and Serlio in the Renaissance.
Vitruvius’s aesthetic theory comprises three central elements: proportio, symmetria, and eurhythmia. In the broadest terms, proportion refers to the relationship of part to part and parts to whole. Optical refinements fall into the category of eurythmia, the application of proportional alterations to “correct” subjective distortions. Optical correction requires symmetry, or a system of symmetries, on the basis of which changes can be incorporated in response to contingencies. Contingent factors including the site, and blocking by crowding also warranted structural adjustments to symmetry. Symmetry is fractional and numeric, with ten (telion) the perfect number (the number of digits on both hands) on which all ratios are based.
Panofsky posits a disjunction between technical and objective measurements in the Greek theory of proportions. Classical theory also distinguishes between beauty and truth, perception and reason, and beauty and tectonics. Proportion is “organic” and anthropometric, based on the human body and its constituent parts. Proportions are serial and fractional:
When, according to Galen, Polyclitus described the proper proportion of finger to finger, finger to hand, hand to forearm, foreman to arm and, finally, each single limb to the entire body, this means that the classical Greek theory of proportions had abandoned the idea of constructing the body on the basis of an absolute module, as though from small, equal building blocks: it sought to establish relations between the members, anatomically differentiated and distinct from each other, and the entire body.6
Proportion also refers to the visual, rather than tectonic, relationship between solids and voids in the disposition of architectural elements. Vitruvius establishes a series of norms that dictate the ratios between solids and voids in columns: “The larger the space between the columns, the greater the diameters of the shafts must be. For if an araeostyle temple had columns whose diameter were equal to one-ninth or one-tenth the height of the column, the building would seem flimsy and inconsequential, because all along the intercolumnal spaces the air itself seems to diminish the apparent thickness of the shafts.”7 Alberti paraphrases this passage, but includes a brief discussion of the structural consequences of column spacing.8 In other words, Vitruvius regards columns as both structure and ornament.
Vitruvian optical refinements include hypotrachelium contraction, entasis, stylobate curvature, column inclination, fluting adjustment, and surface inclination. Hyptrachelium contraction refers to the ratio between the diameters of the tops and bottoms of columns. Optical correction dictates adjustments according to the height of the columns:
The neck contraction of the uppermost surface of the columns, it seems, must be made so that if the column measures up to fifteen feet, the diameter at the bottom should be divided into six parts and the diameter at the top should measure five of these parts. Again, if a column ranges from fifteen to twenty feet, the bottom of the shaft should be divided into six-and–one-half parts and the uppermost diameter of the column should measure five-and-one-half of these units, etc.9
Entasis refers to the swelling curvature within a column shaft, and was probably implemented by stretching a circle to form an ellipse. (A diagram that was originally appended to the scroll for Book Three has never been found.) Entasis, in Greek, means tension or bowing. Stylobate curvature refers to the “dressing down” of the stylobate relative to a level datum (Fig. 1). “The stylobate should be leveled so that in the middle it has an increment provided by the scamilli impares. For if it is constructed exactly on the level, it will appear somewhat hollowed to the eye.”10 A catenary curve reflects the curvature of the stylobate (the capitals are not set on level but according to a uniform unit, such that whatever addition was made to the stylobate repeats on the upper level). Vitruvius prescribes inclining all surfaces above the capitals by one-twelfth the height of the surface, and increasing the number of flutes in interior columns. “The corner columns, moreover, must be made thicker than the others by one-fiftieth of their diameter, because they are cut into by air on all sides and therefore seem more slender to the viewer. Thus where the eye deceives us, reasoning must compensate.”11 These corrections were, according to Panofsky, applied only by “rule of thumb.”
These adjustments to the diameter are added because of the extent of the distance for the ascending glance of our eyes. For our vision always pursues beauty, and if we do not humor its pleasure by the proportioning of such additions to the modules in order to compensate for what the eye has missed, then a building presents the viewer with an ungainly, graceless appearance.12
Although references to optical correction abound, the extent to which it was actually deployed in architectural practice is difficult to assess. Columns almost universally incorporated entasis. The contract that was drawn up between Michelangelo and the executors of the estate of Julius II stipulates the configuration and dimensions of forty carved figures: “Around said casket comes six pedestals, on which come six figures of the same size, all six seated; then, on the same level where these six figures are, above that face of the tomb which attaches to the wall, emerges a shrine which goes up about thirty-five palmi, in which go five figures larger than all the others, because they are farther from the eye.” The design for the Tomb for Julius II underwent a series of iterations that changed the number and dimensions of the sculptures, but optical correction was retained as an organizing principle.
On the other hand, evidence suggests that optical correction was largely a theoretical concern that was implemented only haphazardly. Alberti’s speculative project for a triumphal arch includes prescriptions for the size of statues: “The height of the statues set at the very highest level should be no less than one sixth and no more than that of the first set, positioned above the columns,”13 although it is not clear how the size of the statues relates to the overall scale of the building.
The principles of optical refinements were reiterated in many Renaissance treatises. Although the geometric portion of the scientific aspect of optical correction was subjected to the rationalizing impulses that characterize the Italian Renaissance through quantification, the physical portion was accepted uncritically, for reasons that invite speculation.
Alberti’s On the Art of Building in Ten Books contains references to Vitruvius “system,” although he doesn’t address the topic in great detail. Alberti amplifies some of Vitruvius principles but omits others. He proposes increasing the number of flutes as an alternative corrective to increasing the thickness of corner columns. He also proposes spiral fluting as a strategy for increasing the apparent thickness of a column. “Of spiral fluting there are different kinds, but the less the line deviates from the vertical, the thicker the column appears.”14 Sebastiano Serlio discusses optical correction in Tutte l’opere d’architettura et prospectiva di Sebastiano Serlio. Serlio, paraphrasing Vitruvius, invokes the erosion caused by the density of air as objects recede from a viewer in two instances. He describes a method for assigning numeric values to the distortion  of vertical dimensions (Fig.2):
Then, at eye level–the eye should be the centre–he should draw the quarter part of a circle. Following that, at the place where he intends to put the elements to be made at eye level, he should draw a line on the wall at the said level, and from that line upwards draw the intended element the size that he wants all the others to appear. Then, from the top of that element he should draw a line to the centre of the eye and, where that line intersects the curved line, divide the circle into equivalent parts. He should then draw lines from the centre so that they pass through the circle and strike the said wall. These divisions on the wall will get larger and larger, such that at a distance they will appear the same size. 15
In his notebooks, Leonardo da Vinci describes a theory of perspectival proportion that involves the dissection of the projection of an object by a transparent plane (Fig.3):
Perspective is nothing else than seeing a place (or objects) behind a plane of glass, quite transparent, on the surface of which the objects behind that glass are to drawn…The vertical plane is a perpendicular line, imagined as in front of the central point where the apex of the pyramids converge. And this plane bears the same relation to this point as a plane of glass would, through which you might see the various objects and draw them on it. And the objects thus drawn would be smaller than the originals, in proportion as the distance between the glass and the eye was smaller than that between the glass and the objects. 16
On the other hand, Leonardo includes a discussion of the effect of air on perception. Leonardo assigned numeric values to the dimensional distortions apparent in an object as its distance from a spectator increased. Serlio derived much of his information about the related topic of perspective from Leonardo.
Vitruvius attributes the diminution of objects the greater their distance from a viewer to the viscosity of the air that surrounds them. Air cuts into or erodes objects. This theme persists in Renaissance treatises. Alberti alludes to this phenomenon: “It is obvious, for example, that columns seem narrower in the open air than in an enclosed space.”17 George Hersey points out that everything we know about classical architecture comes from Vitruvius. Ancient authority played a vital role in Renaissance architecture and architectural theory. Choay ascribes Vitruvius’s central role in Renaissance architectural theory in part to the obscurity and ambiguity of his writing.
Architectural treatises that combined text and illustrations were an innovation that had far-reaching consequences. A representative image is a woodcut that comes from Cesariano’s Italian translation of Vitruvius, for which no English translation exists, as far as I can tell (Fig.4). It shows Ionic architecture and a compendium of optical effects, and combines elements of linear perspective and orthographic projection. The spectator stands on the bottom edge of the picture plane. What appears at first glance as simple orthographic projection is complicated by the perspective treatment of the cornice, whose vanishing point terminates at the spectator’s eye. Surface inclination appears as the canted sculpted figure on the building’s roof. Entasis is indicated by the curved lines on the column shaft.
Vaughn Hart has noted the similarity between illustrated Renaissance architectural and scientific treatises (Fig.5). Their publication and translation from Latin into other languages and vernaculars, a consequence of developments in printing, stimulated the dissemination of humanist Renaissance ideals, but also exposed these ideals, which had been the cloistered province of the “literate” (those who knew Latin), to the light of day.18 They were the sites where the competing claims of ancient authority and historic precedent on the one hand and progressive scientific inquiry, which eventually took the form of Cartesian philosophy and the science of Galileo, on the other were played out. Perrault, who was after all a physician, published Ordonnance des Cinque Especes de Colonnes in this context.
