Brunelleschis perspective system essay

Linear perspective , a system of creating an illusion of depth on a flat surface. Linear perspective is thought to have been devised about by Italian Renaissance architect Filippo Brunelleschi and later documented by architect and writer Leon Battista Alberti in Della Pittura.

Linear perspective was likely evident to artists and architects in the ancient Greek and Roman periods, but no records exist from that time, and the practice was thus lost until the 15th century. The three components essential to the linear perspective system are orthogonals parallel lines , the horizon line, and a vanishing point.

So as to appear farther from the viewer, objects in the compositions are rendered increasingly smaller as they near the vanishing point. George Killing the Dragon c. As the limitations of linear perspective became apparent, artists invented additional devices e.

This understanding of pre-Albertian architecture culture sharply alters our concept of the historical transmutation of proportional methods that occurred in the Renaissance at the theoretical level. To dissect this factually and discursively dubious yet stubbornly entrenched narrative, in which many Renaissance historians appear still to take so much comfort, is beyond the scope of this paper.

Ancient Greek And Roman Art

The point is to grasp the underlying denial of the forces of time in Albertianism, and to understand the alignment of proportional practice with those same forces in the fluid methodologies of building-in-time. It was the design-build system of building-in-time and its infrastructure of procedural guidelines that made possible the production of the many extraordinary long-durational works that characterize pre-modern architecture — so many that even a bare list of works might not fit in this paper.

I will briefly cite just a few examples in which the dynamic, flexible process of proportion design is particularly evident. The Pisa duomo group is a classic instance of durational proportions Figs. It is also an extreme case: three buildings of diverse typologies begun at intervals spanning a century — , plus the monumental burial ground, the Campo Santo begun In good part the causes of this harmony are obvious in the uniformly lucid geometric massing and overall shaping of the buildings, their open and blind arcading, uniform material, color, and ornamental patterns, with all these aspects developing various modes of concatenate planning in their close, consistent interrelationships and cross-referencing.

An omnipresent key to the unity resides in proportions and alignments, much of it hidden in plain sight.

For example, the three main buildings rise to the same height, as do the facing baptistery cylinder and duomo facade, itself close to fitting within a square. Perhaps what is most uncanny and revealing of the creative power of building-in-time is how, even as the buildings underwent change and multiplied, relationships of proportion and alignment were maintained in imaginative, disciplined concatenation and retrosynthesis. Originally in the nave and transept lengths of the duomo were proportioned A century later, the nave determined the size and position of the baptistery, whose cylinder aligned with extensions of the nave walls, while the distance between the two buildings was set at 76 meters, or approximately the total length of the church Fig.

Similarly, the main piers in the baptistery were invisibly aligned with the nave arcades.

Rather astonishingly, when the nave was extended and given a new facade, normative proportions were maintained between the two buildings: the new nave length was made equal to the distance from the new facade to the opposite side of the baptistery Fig. Like the baptistery, its position was determined by lines extended from the duomo, but now in an asymmetrical, triangular configuration rather than parallel projection as in the duomo nave and baptistery.

Another instance of a lucid network of proportions and alignments developing over time was the Piazza della Signoria in Florence Trachtenberg: Ch. A set of plans trace the evolution of a century-long chain of proportional concatenation.

The Definition of Perspective in Drawing

It begins with the grid of the palace plan of Fig. The doubling of this distance resulted in the length of the main wall, which, divided by five between end wall centers , yielded the module in question b. This operation produced a theoretically square courtyard area and a zone of great halls proportioned , with supporting piers correctly placed at modular intersections. Next, the ideal plan of the piazza is concatenated from the palace plan around Fig.

The final step results in a precisely aligned and proportioned perspective on the piazza. A center line divides it into optically equal wedges and the viewing distance to the visual axis of the main object in view, the palace tower, is equal to its height Fig. Piazza della Signoria, spatio-visual geometry of the main perspective from the Via dei Calzaiuoli mid-late 14th century. Building-in-time, like all such programs, was not always smooth sailing.

In the notorious case of the failed Duomo Nuovo project in Siena, the problem was not any disdain of correct proportions Figs. To the contrary, as I explain in Building-in-Time , the Sienese planners were obsessed with proportions, so much so that excessive attention to proportional consistency appears to have been a principal factor behind the grave structural miscalculation that lead to the abandonment of the project in No study of Italian pre-modern architecture would be complete without new St. It involved much the same problematic as Siena, in that it was in almost every respect a disproportionate project.

It was disproportionate to material and structural means, not to mention spiritual ideals, and it was only by the grace of God-sent Michelangelo, as he saw himself, that it was ever finished. Essentially this completion was achieved by sharply altering proportions, those between the central domical unit and the surrounding matrix, which was radically reduced. The story was all about proportion, disproportion, and negotiating the realms of architectural desire, possibility, and reality.

Because of its improbable triumphant conclusion, we tend to forget that St. Maarten van Heemskerck, St. It seems reasonable to assume that Brunelleschi devised the method of perspective for architectural purposes—he is said by Manetti to have made a ground plan for the Church of Santo Spirito in Florence on the basis of which he produced a perspective drawing to show his clients how the church would look once built.

We can compare this drawing left with a modern photo of the actual church below. It is clear how effective the new technique of mathematical perspective was in depicting spatial reality. But this was just the beginning.
