Johannes Mathesius

In 1540 a lucky speculation in mines let him realize his ambition of a clerical calling, and he became a theological student at Wittenberg.

The recommendations of Justus Jonas and Georg Rörer got him the prized honor of a seat at Luther's table.

It is not known exactly how long Mathesius was Luther's guest, but it was probably no longer than the period of May to November 1540 covered by his notes of the Table Talk.

Mathesius took the degree of master in September 1540, spent nineteen months more in study, and then returned to Joachimsthal as deacon.

In 2013, a newly discovered mineral from Jáchymov (St Joachimsthal) was named mathesiusite in his honor and a detailed description was published in 2014.
