Mathematical Treasure: Peuerbach’s and Regiomontanus’s Ptolemy

Author(s): 
Frank J. Swetz (The Pennsylvania State University)

Regiomontanus [Johannes Müller] (1436-1476) was a German mathematician and astronomer. He was a student and friend of the leading European scientist Georg von Peuerbach (1423-1461). Peuerbach began a translation of Ptolemy’s Almagest from Greek into Latin but could not complete the task. Regiomontanus took up the task and published Epytoma Joan[n]is De Mo[n]te Regio in Almagestum Ptolomei [Epitome of the Almagest] in 1496.
