Coffee with a Codex: Astronomical Volvelles
An informal lunch or coffee time to meet virtually with Kislak curators and talk about one of the manuscripts from Penn's collections. Each week we'll feature a different manuscript and the expertise of one of our curators. Everyone is welcome to attend.
On February 15, Curator Dot Porter brought out LJS 64, a collection of handmade diagrams, many with moving parts, designed to accompany the work Theoricae novae planetarum by 15th-century Austrian astronomer Georg von Peurbach. The diagrams demonstrate increasingly complex planetary motion. (OPenn, BiblioPhilly, CWAC recording)
