Libellus de sphaera

Also known as John of Holywood; author's name appears as Joannis de Sacro Busto on title page. He is believed to have been born circa 1200, educated at Oxford, and was probably of Scottish origin. He took holy orders and spent most of his life in Paris, where he was an outstanding scholar in mathematics and astronomy; he died in Paris in the mid-13th c. De Sphaera is one of three extant works and is an elementary treatise on astronomy. It was used widely throughout Europe beginning in the mid-13th century. The first publication occurred in Ferrara in 1472. Caltech's copy is a German one, with imprint Wittenberg, 1561. [See DSB (1981)12:60-63.]

Bound with Latin MS pages (3 leaves, front). Additional notes in similar hand within textblock. Evidence of many owners in title page inscriptions (mostly crossed out).
