Marcella Giulia Lorenzi and Biagio Di Carlo and Sandra Leone

Statement

During the Art and Science project, Biagio Di Carlo, Architect and former professor, was invited by Marcella Giulia Lorenzi, artist, Chair of the project and Sandra Leone, Art Director, to make a bamboo structure, using the reciprocal joint of Leonardo da Vinci. The "Mauro Francaviglia" Cultural association is dedicated to the memory of Mauro Francaviglia, Marcella's late husband and collaborator, Professor at Universities of Turin and of Calabria, friend of the late Bridges Chair Reza Sarahangi: they met during Bridges and other conferences and were organizing to host one in Italy. The Project is in collaboration with Calabria Region (2014-2020 Pac fundings, year 2019) and Museum of Copper and ancient crafts in Tessano-Dipignano.

Artworks

On October 10th, 2020, a small group (due to Covid19 restrictions) built a bamboo dome, using Leonardo da Vinci's reciprocal frame joint, in the courtyard of the Museum of Copper and ancient crafts in Tessano, small village near Cosenza, Calabria, south of Italy. The 2v geodesic dome is obtained by halving the equivalent geodesic sphere. The sphere refers to the geometry of an icosidodecahedron which is one of the 13 Archimedean polyhedra obtained by truncating the 20 vertices of the dodecahedron. The icosadodecahedron has 32 equal regular faces (12 pentagonal and 20 triangular, 60 edges and 30 vertices). By triangulating the 12 pentagonal faces we obtain a polyhedron composed of only triangles, a quasi-spherical geodesic structure.
