The Medici collection of scientific instruments, assembled by Cosimo I, was installed toward the mid-sixteenth century in the Map Room of the Palazzo Vecchio. At the end of the century, Grand Duke Ferdinand I moved the collection to the Uffizi in a purpose-built locale: the Stanzino delle Matematiche, or Small Mathematics Room. The collection expanded considerably between the late sixteenth and early seventeenth centuries. It was successively placed in the adjoining Camera delle Matematiche, or Mathematics room, which also housed the instruments gathered by Ferdinand I, the ones purchased in Germany by Prince Mathias, and those formerly owned by Sir Robert Dudley. The Medici collection also included globes, telescopes, and optical devices, most of which were stored at the Pitti Palace. In 1775, these substantial holdings were transferred to the Physics and Natural History Museum, located in the Palazzo Torrigiani in Florence. The Physics Museum also received the Galilean relics, which in 1841 were installed in the Tribuna di Galileo designed by the architect Giuseppe Martelli.
