Last update December 14, 2014

From this page you can download diagrams of several Greek mathematical works reproduced from the manuscripts: Euclid's Elements, Books 2-4, 6, 11-13, Phaenomena, Optics, as well Arabic translation of Menelaus' Spherics.

Elements III.13: diagram in Heiberg's edition and in codex P

Example
In proposition III.13 of the Elements, Euclid proves (by contradiction) that two circles cannot touch at two points either internally or externally. All the modern editions have a diagram similar to the one in the left, which appears in Heiberg's edition. However, the diagram found in the manuscripts is like the one in the right, which is a faithful reproduction from Vatican manuscript of the ninth century. Here, the second circle ΑΚΓ touching externally at two points to the first circle ΑΒΓΔ is represented by a lunule, which Heiberg (more precisely August, whose diagrams were copied by Heiberg) has changed into a circle.
