Il Teatro del Mondo or “Venetian theater” was built by Aldo Rossi in 1979, for the Theater and Architecture” sections of the 1980 Venice Biennale, in conjunction with the exhibition Venice and the scenic space. Anchored at the Punta della Dogana, this ephemeral floating theater then sailed across the Adriatic to what was then Yugoslavia, visiting Dubrovnik among other ports that were part of the former Venetian colonies, after which it was dismantled. Through his many drawings for the theater, Rossi analyzed and condensed the Venetian identity, its physical, geographic, architectural and mythical reality. This “singular” construction, as the architect described it, “draws its substance and its image from technology and history.” In it many references converge: primitive, proto-renaissance Florentine kiosks, renaissance theaters, Elizabethan theaters, lighthouse architecture and especially 18th century Venetian architecture, known for its floating structures built for Carnival (ephemeral stage sets inserted into the moving landscape of the city). Thus, it is the typology of the city that creates the scenario. And this mobile theater-boat became a fragment of the urban history, a quasi-metaphysical image tasked with representing Architecture. With a height of approximately 25 meters, comprised of a cube topped by an octagon, it is made of steel poles and a wood skin. Between physical object and image, large-scale model and drawing, this universal theater creates a blurred vision that makes it hard to read, representing the real in a kind of dreamlike meta-reality.
