Sphaera mundi is a 1635 Latin cosmography and astronomy treatise by the Jesuit mathematician Giuseppe Biancani, printed at Modena by Giuliano Cassiani for scholars and students. Its pages show geometric diagrams of circles, the Earth and Sun with lines of construction, and a carved ornamental headpiece with interlaced scrollwork, grotesque animals and a central shield, offering designers diagrammatic linework and dense decorative border patterns.
