This is a research paper discussing some of the key points in “Transparency: Literal and Phenomenal”
“The Bauhaus, insulated in a sea of amorphic outline, is like a reef gently washed by a placid tide” – Colin Rowe and Robert Slutzky
The Dictionary definition of Transparency states transparency as being something that is clearly evident and present in its absolute visual entirety. Transparency can be literal, as the physical quality of a substance, for example the transparency of a glass wall, or a phenomena like that seen in the quality of organization of spaces. Transparency, as the author describes it, associates with more than just the observable phenomena, it possesses overtones that make obvious its interconnected relationship with spatial orders and organization.
The edifice on which the authors build their argument, deviates from the conventional views of most critics; where discussions on ‘phenomenal transparency’ are dismissed without much scrutiny, the resulting effect restricts the association of transparency particularly to materials used in architecture.
Endowing figures with transparency, as the authors discuss, goes beyond materials. Physical, or literal transparency can be achieved through materials, yes, but phenomenal transparency is a fairly harder concept to grasp and apply. Phenomenal transparency can be achieved when two forms, or figures, ‘interpenetrate’ without compromising line of sight to each other, the authors put it as “Two figures able to interpenetrate without an optical destruction of each other”
In light of the above consideration, conventional understandings begin to cross over into the realm of ambiguity, no longer remaining ‘clear and evident’ as defined by literal definitions of transparency. This is due mainly, to the interpretive nature of spaces that accommodate such “interpenetrating figures” as a result transparency transforms from that which is clear, to something that is equivocal.
This ambiguity is noticed when overlapping figures begin to disrupt spatial dimensions; this disruption is often the result of a common overlapped area, a situation where a visual disconnection is encountered. At this point introducing transparency would restore the disconnection, however, introducing transparent materials may not be the only means through which transparency can be achieved, at this point an important question must be asked: Is there a sense of greater involvement by something beyond the realm of physical transparency that can be added to this particular equation?
To reach a conclusion, one would have to first amount to a greater understanding of the difference between the two transparencies, literal and phenomenal. The authors state, concerning the foregoing discussions of phenomenal transparency in light of spatial context that “it is intended simply to give a characterization of species” the authors then stress on the importance of understanding the distinctions and continue “but also to warn against the confusion of species”.
Literal transparency can be sourced to originate from cubist painting and ‘The Machine Aesthetic’. The key difference between Transparency described in paintings by Cubist artists the likes of Picasso and La Sarraz, and Transparency in Architecture is that in the 2-dimensional platform, transparency remains restricted to pictorial representations and implications of the three dimensions, whereas Architecture, as the authors put it, “Is provided with the reality rather than the counterfeit of three dimensions” the authors state that “literal transparencies become physical fact” and “Phenomenal transparency, for this reason, is more difficult to achieve”.
If the two forms of transparency were presented as dialectic, then if literal transparencies are physical fact, phenomenal transparencies transcend physicality and as a result bypass common observations and perceptions of it. For example, Le Corbusier’s Palace of the League of Nations, a building expressed by the author as the “Essence of that phenomenal transparency which has been noticed as a characteristic of the central post-cubist tradition”, is a building that possesses a minimal display of material transparency and visual flow, instead it works with “planes that are like knives” 1. In a situation like the one Corbusier created within the Palace of the League of nations, the kind of transparency witnessed here is purely experiential, though most of its environment presents hints of various programs and components, only at a specific point does it allow you full visual access to them, such is the nature of phenomenal transparency.
It would suffice to say, that transparency can be deeply influenced by spatial organization, where a semi-pervious entity, like the body of trees in the heart of Le Corbusier’s “Palace of the League of Nations”, act to obstruct the line of sight leading to the Palace entrance quay, only to re emphasize it when the visitor has finished crossing the trees. It is at this point we can inquire on how exactly to attribute traits of phenomenal transparency to this particular building. To delve into this exploration, observation coupled with an intellectual understanding of transparency is required. This observation, that leaks into the realm of studying both the apparent and vague, intrinsic elements present within the spatial organization lead to an understanding of spatial ‘distinctions’.
These distinctions are categorically used in the organization of the entire building to emphasize and frame a visitor’s line of sight. This ‘framing’ effect can be understood as a form of transparency, where one figure or form, interpenetrates with another but instead of being literally transparent, instead frames the figure it is interpenetrating with.
In the same building, the authors express the irrefutable effect of the gardens on the visitor, on crossing the volume of trees the visitor finds himself before the Main assembly hall of the League of nations, yet his gaze is directed sideways towards the gardens and lake, in light of this, is it possible that transparency also lies in the contrast of things?
Perhaps the endeavor of clarifying the spatial context within which phenomenal transparency becomes a possibility is one that requires holistic understandings of all spatial elements ranging from physical materials to the purely equivocal play of vision, volume and void. Perhaps, phenomenal transparency is indeed not the transparent cladding of a building but the setting through which the nakedness of a structure is seen either through contrast or distinction, or both, perhaps its phenomena is woven deeply into the spatial organization of an architectural construct, regardless, it remains a constituent of modern architecture, and its enigmatic presence must be understood, to both categorize, and prevent confusion.
“If we could attribute to space the qualities of water, then his building is like a dam by means of which space is contained, embanked, tunneled, sluiced, and finally spilled into the lake” – Colin Rowe and Robert Slutzky on Le Corbusier’s “Palace of the League of Nations” project
