Penn Library's LJS 64 - Novae theoricae planetarum (Video Orientation)

Video orientation to the University of Pennsylvania Library's LJS 64 - Illustrations to Georg von Peurbach's Novae theoricae planetarum. Diagrams, many with moving parts, designed to accompany the work Theoricae novae planetarum by 15th-century Austrian astronomer Georg von Peurbach, who taught at the universities in Padua and Ferrara. The diagrams demonstrate increasingly complex planetary motion. An early 17th-century inscription on the first flyleaf refers to an edition of Peurbach published in Venice in 1616.
