A close reprint of Landsberg's edition of ca 1497, the first to be published with commentary by Wenzel Faber von Budweis (1455-1518), an astronomer, astrologer and theologian from Bohemia. Sacrobosco's Sphaera Mundi, in which he sets out the basic principles of spherical astronomy, was widely commented upon, corrected and republished across Europe. First written in about 1220, the Sphaera Mundi is "a small work based on Ptolemy and his Arabic commentators antedating the De sphaera of Grosseteste. It was quite generally adopted as the fundamental astronomy text, for often it was so clear that it needed little or no explanation. It was first used at the University of Paris and from the middle of the thirteenth century it was taught in all the schools of Europe. In the sixteenth century it gained the attention of mathematicians, including Clavius. As late as the seventeenth century it was used as a basic astronomy text" (DSB XII, p. 61).
