The sculptures in Piazza de’ Guidi, engraved with glass blocks and silver blades, with a scenographic effect at night, introduce the visitor to the Leonardo route and to the city. It was precisely the idea of a work of high artistic value, capable of dialoguing symbolically with the museum itself and with Leonardo’s legacy, that guided the Municipality of Vinci in the realisation of a competition of ideas, launched in 2003, which saw Mimmo Paladino as the winner. The work, with its geometries and abstract shapes inspired by the polyhedron, the symbol of the Renaissance, evokes Leonardo’s faith in geometry and gives shape to an unusual and evocative urban space.Â
