Cluver, Philipp

Petrus Bertius grew up in Beveren in Flanders and as a young man travelled widely in Europe. In company with so many of his compatriots he moved to Amsterdam as a refugee from religious persecution and after completing his studies there he was appointed a professor of mathematics and librarian at Leyden University. As well as being a prolific writer on mathematical, historical and theological subjects he is known as a cartographer for his editions of Ptolemy's Geographia (based on Mercator's edition of 1578) and for the miniature atlases detailed below. In i6i8 he moved to Paris and became Official Cosmographer to Louis XIII. He was related by marriage to Jodocus Hondius and Pieter van den Keere.
