Euclid's Optics

Another of the fantastically important science manuscripts of the Vatican Library has just come online: Vat.gr.204 is the oldest and best manuscript of a collection of early Greek astronomical works, mostly elementary, by Autolycus, Euclid, Aristarchus, Hypsicles and Theodosius, as well as mathematical works. While the Vatican's most priceless Euclid volume came online a year ago, this was the supplementary one so many have been waiting for.

Following Rome Reborn, I show above Proposition 13, which is accompanied by many scholia, concerned with the ratio to the diameters of the moon and sun of the line subtending the arc dividing the light and dark portions of the moon in a lunar eclipse. The work is thus a basis for Euclidean optics.

The following list of 64 items comprises new scans at high-resolution, and briefly interrupts the multi-part list of low-res black-and-white scans from the Vat.lat. series that I will continue in the next few days.

This is, by the way, Piggin's Unofficial List number 100. Given the enormous rush of manuscripts recently, I am not sure how to keep up the pace. I can no longer cover every new arrival. But we will find some kind of ad-hoc solution to keep most readers of this blog happy.

We also have several new collections, currently only available in digitized black-and-white microfilms. I will simply list these:
  1. Pap.Vat.gr.11
