Caption: Ptolemy (c.100--c.170 CE) with an armillary sphere.
Ptolemy is arguably the greatest of the ancient Greek astronomers.
The crude sketch in the image is based on a wood scuplture by Joerg Syrlin the Elder (c.1425--1491) that was made circa 1469--1474. The wood scuplture is in the choir stalls of Ulm Minster, Ulm, Germany. An image of the original and better description can be found at the Ptolemy iconography site of Robert Derome, University de Quebec a Montreal.
