Erycius Puteanus

[1] He was born in Venlo and studied at the schools of Dordrecht and Cologne (College of the Three Crowns), where he took the degree of Master of Arts, 28 February 1595.

In 1597, he travelled to Italy and met scholars, especially Cardinal Federigo Borromeo, through whom he was appointed professor of Latin at the Palatine School of Milan from 1600 to 1606.

He was loaded with favours by reigning princes: the Archduke Albert appointed him his honorary counsellor (1612), and increased his annual pension by 200 ducats (1614), adding the reversion of Château-César.

One distinctive feature is his extension of the Guidonian hexachord (ut, re, mi, fa, sol, la) with a seventh note bi, accompanied by a justifying cosmological and numerological emphasis on the number seven.

[1] Puteanus provided advice about naming features on the first telescopic lunar map produced by his friend Michael van Langren (1598–1675).
