Upon assuming the title of Grand Duke, Ferdinando I (1549-1609) immediately resumed his father’s cosmographic project, which his brother Francesco had only partially continued. He did not finish the "Guardaroba" in Palazzo Vecchio but had a new "Room of Cosmography" set up in the Uffizi Gallery, which he had frescoed with the two domains united by his father with the annexation of Siena - the Florentine Domain and the Sienese Domain - and in which he placed the great terrestrial globe made by Egnazio Danti (1536-1586) for Cosimo I (1519-1574) and a monumental armillary sphere specially built by the cosmographer Antonio Santucci (?-1613). The room emblematically exalted the name of Cosimo by evoking the three forms of representation of Ptolemaic cosmography, namely, "cosmography" proper, that is, the image of the sky, represented by Santucci’s armillary sphere; "geography", represented by Danti’s terrestrial globe; and "corography", represented by the regional maps of grand-ducal Tuscany. The corographies of Tuscany were painted by Ludovico Buti (1560-1611) on the basis of the two maps drawn by Stefano Buonsignori (?-1589) to illustrate the Vita di Cosimo I (Life of Cosimo I), published by Aldo Manuzio the Younger in 1586.
