Bernardo Buontalenti (Florence, 1531-Florence 1608) was a Florentine stage designer, architect, theatrical designer, military engineer and artist. He was much employed in the design of fortifications, villas, and gardens and is considered one of the most important architects of the Mannerist period (the Medici Villa in Pratolino, the Tribune in the Uffizzi Gallery, the palace of Bianca cappello in Via Maggio, the Forte Belvedere, the Buontalenti Cave in the Boboli Garden, the project for the new city of Livorno, etc.) . He was also a great mechanic, and an excellent mathematician. Besides tha, he is also traditionally considered the inventor of modern gelato. The Grand Duke Cosimo I de’Medici wanted him to organize an opulent banquet to celebrate the Spanish deputation, that had to stand open-mouthed in front of so much splendour. Buontalenti invented a new dessert for the occasion: a sorbet made with ice, salt (to lower the temperature), lemon, sugar, egg, honey, milk and a drop of wine. His cold cream was flavoured with bergamot and orange and was the forerunner of the modern Florentine cream. Buontalenti was an expert of the ice conservation; he has indeed projected some cold storage room both in the Boboli Garden and in the Cascine area. Near the Medici Fortress there is a street called Via delle Ghiacciaie (i.g. “icehouse street”), that owes its name to the cellars covered with isolating cork and wood panels, with a system of canes that let the thawed ice flow down. Buontalenti probably even built a sort of manual whisk to whip up the cream.
