of Ptolemy, all measured with perfect accuracy and corrected after the most recent authorities, with exact charts of navigation and their scales for measuring and degrees, done with supreme diligence; and with these are all the names both ancient and modern...The images of plants and animals are exactly in line with the maps...The terrestrial globe is marked distinctly and it is possible to use it for all the operations of the astrolabe perfectly” - Giorgio Vasari - Lives of the Most Excellent Painters, Sculptors, and Architects As well as the maps on the cabinets, other images adorned the room. Up to 300 portraits of famous people of the day hung around highest perimeters of the walls and would be revealed from beneath green cloth curtains. In between the cabinets doors, were to be mounted natural history drawings of flora and fauna that, as Vasari indicated above, would have been in line with its corresponding regions on the maps in a similar fashion to the objects that are revealed from beneath their corresponding region. The collected artifacts were arranged and maintained by curators and conservators known as guardarobiere, in a similar manner to the role of the contemporary museum. The rarer an item, the more attractive it was to the collector and desired for the collection. Objects from the Americas or New World as it was then referred to, were particularly valuable at this time as Italians were not allowed to travel there without permission from Spain or Portugal. Instead, they explored this region vicariously through objects and the Medici possessed a significant collection of artifacts from the Americas, largely collecting featherwork. Vasari intended the worldly representation in the guardaroba to be seen in relation to the larger cosmos, represented by a celestial sphere in the centre of the room and painted constellations on the ceiling. He also had grand visions of two large globes, a terrestrial and celestial hidden behind a false ceiling that could be lowered impressively via a pulley system into the room below. The room was also to display a copy of the 1484 clock made for Lorenzo de Medici by Lorenzo della Volpaia. An Antonio Santucci (b.? d.1613) armillary sphere that is now at the Florence Museum of the History of Science, was also displayed in the guardaroba along with a second, earlier armillary sphere that is now lost. It is the relationships between these objects
