Oronce Fine's Le Sphere du Monde
Oronce Fine (1494-1555) was a French mathematician and astronomer who served as the Chair of Mathematics at the Collége Royal from 1531 until the time of his death. He revised the classical works of great masters such as Ptolemy, Aristotle and Sorobosco; compiled encyclopedic texts on mathematics; and developed astronomical measuring instruments. This illustration is from page 2 of the 1551 edition of his Le sphere du monde. It shows the interaction between the Four Elements and the Four Humours. It was preceded in 1549 by a royal manuscript edition. Harvard University's Houghton Library has digitized its 1549 manuscript edition of Le sphere du monde: proprement dicte Cosmographie.
This illustration on page 45 of Le sphere shows the division of the earth into its various zones with the boundaries of the zones including the Tropic of Cancer, the Tropic of Capricorn, and the Arctic and Antarctic circles.
