Title page of Quadrans Apiani by German mathematician and astronomer Peter Apian, 1532. Artist: Unknown
Title page of Quadrans Apiani by German mathematician and astronomer Peter Apian, 1532. The illustration shows his recently invented quadrant. Apian (1495-1552) established his reputation by issuing a world map in 1520, and the 1524 publication of his work of geography Cosmographia. In 1527 he published Rechnung, an arithmetical textbook, which included the first printed account of Pascal's triangle. Apian's most important work in astronomy was his Astronomicum Caesareum of 1540, which contained detailed descriptions of five comets.
