The Studiolo was a small painting-encrusted barrel-vaulted room in the Palazzo Vecchio, Florence, commissioned by Francesco I de' Medici, Grand Duke of Tuscany. It was completed for the duke from 1570-1572, by teams of artists under the supervision of Giorgio Vasari and the scholars Giovanni Batista Adriani and Vincenzo Borghini. This small room was part-office, part-laboratory, part-hiding place, and part-cabinet of curiosities.
