Prosdocimus_de_Beldemandis Knowpia

Prosdocimus de Beldemandis (or Prosdocimo de' Beldomandi) (died 1428) was an Italian mathematician, music theorist, and physician.

He studied at the University of Padua and the University of Bologna. The earliest works by him date from the early 15th century. He took the doctorate in arts at Padua on 15 May 1409, and received a physician's license on 15 April 1411. In 1412 he stayed in Montagnana, where he wrote a number of treatises. From c. 1420/22 to 1428, the year of his death, Prosdocimus taught a wide variety of subjects at Padua. His was interested in, among other things, arithmetic, music, astronomy, and astrology; this range of interests, however, was common for a Paduan doctor of his day. He wrote the last significant treatise on the art of musical notation as practiced by the Italians. He was held in high regard long after his death: some of the non-musical treatises were reprinted in the 16th century, and Luca Pacioli ranked him alongside Euclid and Boethius.
