PTOLEMAEUS, Claudius; THEON of Alexandria.

Inquire · Offered by Peter Harrington

Theonis Alexandrini in Claudii Ptolemaei magnam construction nem commentariorum lib. XI. Editio princeps. Theon, father of the celebrated female mathematician and philosopher Hypatia, composed his commentary on the Almagest as a redaction of his lectures, said to have been given at the Museum in Alexandria. Edited by Joachim Camerarius (1500-1574), the commentary is of particular value to modern scholars because it preserves information about now-lost mathematical and astronomical treatises. The book was issued as a companion volume to the editio princeps of the Almagest, published the same year by Walder.
