Last month, I recorded video orientations for two of my favorite manuscripts from the Schoenberg Collection at Penn.

LJS 445 – Prenosticatio

LJS 497 – Canones vel operationes in operando quadrante

These manuscripts are drawn from my upcoming exhibit on medieval astronomy, which will be displayed at the Medieval Academy of America meeting in 2019. I am also building an online version of this exhibit at aylinmalcolm.com/astro.
