With the discovery of the New World, geographic publications compiled to update the information furnished by Ptolemy (2nd century) proliferated. The humanists’ libraries abounded in books of geographic interest, and many sumptuous, costly codices were produced by the Florentine workshops in the 15th century. Lorenzo the Magnificent (1449-1492) owned several "pictures" with geographical charts and a superb codex of Geografia ‘painted’ by Piero del Massaio (15th century), which then passed into the hands of Cosimo I (1519-1574), a worthy heir to the Laurentian concept of possessing the universe through knowledge. A splendid volume of nautical charts attributed to Francesco Ghisolfo (16th century) was donated by the Martelli family to Francesco de’ Medici (1541-1587) with an erudite dedication that exalted the name of Cosimo in an elegant intermingling of Greek and Latin: "Te Cosmo Cosmu Cosmon Francisce donamus quia munere dignus es", that is, "We offer you the Cosmos, o Francesco, ornament of the Cosmus (and of Cosimo)".
