Italian architect and sculptor (also spelt Kalandario). Reliable Venetian chronicles from the 15th century onwards not only praise him as the architect of the Doge's Palace in Venice and as a sculptor but also record that the Venetian government ('Signoria dogal') valued his advice when building palaces, towers and other public works. He was the most important sculptor and architect of the 14th century in Venice, although no building other than the Doge's Palace can now be attributed to him. //
