REGIOMONTANUS (1436-1476)

This article appears in Volume V23, Page 40 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: RAY-RHU
REGIOMONTANUS (1436-1476) , German astronomer, was born at Konigsberg in Franconia on the 6th of June 1436. The son of a miller, his name originally was Johann Muller, but he called himself, from his birthplace, Joh. de Monteregio, an appellation which became gradually modified into Regiomont anus. At Vienna, from 1452, he was the pupil and associate of George Purbach (14231461), and they jointly undertook a reform of astronomy rendered necessary by the errors they detected in the Alphonsine Tables. In this they were much hindered by the lack of correct translations of
Ptolemy
 's works; and in 1462 Regiomontanus accompanied Cardinal Bessarion to Italy in search of authentic manuscripts. He rapidly mastered Greek at Rome and Ferrara, lectured on Alfraganus at Padua, and completed at Venice in 1463 Purbach's Epitome in Cl. Ptolemaei magnam compositionem (printed at Venice in 1496), and his own De Triangulis (Nuremberg, 1533), the earliest
work
  treating of trigonometry as a substantive science. A quarrel with George of
Trebizond
 , the blunders in whose translation of the Almagest he had pointed out, obliged him to quit Rome precipitately in 1468. He repaired to Vienna, and was thence summoned to Buda by Matthias Corvinus, king of
Hungary
 , for the purpose of collating Greek manuscripts at a handsome salary. He also finished his Tabulae Directionum (Nuremberg, 1475), essentially an astrological
work
 , but containing a valuable table of tangents. An outbreak of war, meanwhile, diverted
the king's attention from learning, and in 1471 Regiomontanus settled at Nuremberg. Bernhard Walther, a rich patrician, became his pupil and patron; and they together equipped the first European observatory, for which Regiomontanus himself constructed
instruments
  of an improved type (described in his posthumous Scripta, Nuremberg, 1544). His observations of the
great
  comet of January 1672 supplied the basis of modern cometary astronomy. At a printing-press established in Walther's
house
  by Regiomontanus, Purbach's Theoricae planetarum novae was published in 1472 or 1473; a
series
  of popular calendars issued from it, and in 1474 a volume of Ephemerides calculated by Regiomontanus for thirty-two years (14741506), in which the method of " lunar distances," for determining the longitude at sea, was recommended and explained. In 1472 Regiomontanus was summoned to Rome by Pope Sixtus IV. to aid in the reform of the calendar; . and there he died, most likely of the plague, on the 6th of July 1476.
