Justura rubit est prius aut praes Jantius unguam..
|Petrus Apianus (1495 –1552), also known as Peter Apian, was a German humanist, known for his works in mathematics, astronomy and cartography. The lunar crater Apianus and minor planet 19139 Apian are named in his honour. In 1540, Apian printed the Astronomicum Caesareum, dedicated to Charles V. Charles promised him a truly royal, appointed him his court mathematician, and made him a Reichsritter (a Free Imperial Knight) and in 1544 even an Imperial Count Palatine. All this furthered Apian's reputation as an eminent scientist. Apian's work included in mathematics—in 1527 he published a variation of Pascal's triangle, and in 1534 a table of sines— as well as astronomy. In 1531, he observed a comet and discovered that a comet's tail always point away from the sun. (Girolamo Fracastoro also detected this in 1531, but Apian's publication was the first to also include graphics.) He designed sundials, published manuals for astronomical instruments and crafted volvelles (Apian wheels), measuring instruments useful for calculating time and distance for astronomical and astrological applications. Apian was followed by his son Philipp (1531–1589), who, in addition to his own research, preserved the legacy of his father.|
