Orditi della Razionalità, edited by Riccardo Caldura, offers a selection of works that have had a very widespread diffusion on an international level, strongly relaunched in the second half of the 1960s and continued throughout the following twenty years. The city of Padua itself, in this same period, would become one of the major centers for the diffusion of relevant experiments attentive to the operational implications between art, perception, design and the then new technologies. And it is in this climate that the extraordinary collection of works is formed that tell of another Biennial, that of San Martino di Lupari conceived by the artist Edoer Agostini, and which are part of the Museum dedicated to an extraordinary scholar such as Umbro Apollonio.
