>This was the pseudonym of Johannes Muller, who was responsible for the revival and advancement of trigonometry. In astrology, his reputation lies in his development of a system of house division. He entered the University of Leipzig at the age of 11 and then in 1452 went to Vienna to study mathematics and astronomy. He was involved with his teacher, Peuerbach, in a new translation of Ptolemy's work from the original Greek as existing versions were riddled with errors which had arisen from Latin translations from the Arabic. After Peuerbach's death, he continued and completed the work in 1463. In 1472, after establishing a workshop in Vienna, he completed the observations of a comet which would be used to identify the comet 200 years later as Halley's Comet. He published several works on trigonometry and algebra. He was summoned to Rome in 1475 to advise on reforms of the Julian calendar. He was appointed Bishop of Regensburg but died before he could take up the position on 6 July 1476.< Source: Bernadette Brady.
