In 1530 he took his degree as master of arts.
He went to Cambridge as a sizar of Magdalene College in 1616, migrated to Peterhouse in 1618, was bachelor in 1619 and master of arts in 1623.
Stimulated by the example of Charles IV., who had founded the university of Prague in 1348, Casimir on the 12th of May 1364 established and richly endowed the first university of Cracow, which had five professors of Roman law, three of Canon law, two of physics, and one master of arts.
But at the end of a year he renounced the pursuits of commerce, returned to the university of Basel, and was admitted to the degree of bachelor in philosophy, and a year later, at the age of 18, to that of master of arts.
At, or only a very little beyond, the usual age he entered the recently (1348) founded university of Prague, where he became bachelor of arts in 1393, bachelor of theology in 1394, and master of arts in 1396.
