Ptolemy’s Cosmography was rediscovered in the Humanist period in a Greek codex brought to Florence at the end of the 14th century, translated into Latin by Iacopo Angeli da Scarperia, and accompanied by accurate cartographic tables, in manuscripts and in the first incunabula. Leonardo records the book in his lists of books, and above all uses it as a model for the editorial project of the treatise on anatomy: the tables of the human body (the “minor world”) were to have resembled those of Ptolemy’s Cosmography.
