View of the Tribune

The Tribune was realized between 1581 and 1583 by architect Bernardo Buontalenti “to keep jewels and embellishments of the Grand Duke”, Francesco I de’ Medici. According to the concept of museum in that period, the Tribune did not just display works of art, such as sculptures and paintings, but also extraordinary natural items, including precious stones. It was a cabinet of curios, containing a condensate of knowledge.

The structure is octagonal because according to Christian tradition eight is the number which draws near Heaven. Besides, in ancient times octagonal plans were recurrent in the construction of important buildings as well as of baptisteries and basilicas. The dome, symbol of the Vault of Heaven, has an external lantern with a weathervane whose movements are internally reproduced on a painted wind rose. The lantern also works as a sundial: during both equinoxes and solstices the Sun passing through a hole displays the celestial mechanics also to “those who are inexperienced with planets and the motion of heavenly bodies”. Francesco I conceived the iconography of the Tribune’s decorations and furniture as a full cosmos featuring the four elements.
