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. Here the prince tinkered with alchemy and fingered his collection of small, precious, unusual or rare objects, under the organizing vista of thematic canvases, which are rather larger than most cabinet paintings.
