Colour enhanced illustration from Petrus Apianus', La cosmographie (1551) showing proof for the sphericity of the earth by observing the shape of the shadow cast on the moon during a lunar eclipse. Petrus Apianus (1495-1552) was a German humanist, known for his works in mathematics, astronomy and cartography. In 1524 he produced his Cosmographicus liber, a respected work on astronomy and navigation that was to see at least 30 reprints in 14 languages. In 1527 he published a variation of Pascal's triangle, and in 1534 a table of sines. In 1531, he observed a comet and discovered that a comet's tail always point away from the sun. In 1540, he printed the Astronomicum Caesareum, dedicated to Charles V who appointed him his court mathematician. | |
