Only twenty-three manuscripts were digitized this week. February 11 is the commemoration of the Lateran Treaty, and so the library was closed for several days this week. The collection is mostly from Reg.lat, with three each from Pal.lat and Vat.lat, the later all being 19th Century of antiquarian interest from the circle of Angelo Mai

The manuscript Reg.lat.1262 contains two different works on using a quadrant. To the right is f.7v, part of the explaination of how the quadrant is designed using a compass. According to the flyleaf, it was owned in 1546 by François Rasse des Neux, a Parisian doctor and poet. He inherited the job of Royal doctor from his father and served Catherine de Medicis, before converting to Calvinism.

To the right is f.56r from Reg.lat.1670, a 15th C copy of Ovid's Metamorphoses. Here book six, containing the story of Arachne, begins.
