Marcin Kober, of Polish descent, was born in
Wrocław, Poland. Trained as a
guild painter, he traveled through Germany for three years as a wandering
journeyman to gain experience in different workshops. In 1583 he came to the
Polish–Lithuanian Commonwealth from
Magdeburg and become court painter of King Stephen Báthory and Queen Anna Jagiellon. He was appointed the royal
servitor and at the court he met his wife Dorothea, also a painter specializing in painting crests. After the King's death he returned to Wrocław, from where he joined the Imperial court of
Rudolf II in
Prague as a portrait painter, due to the conflict with other guild painters in the city. The emperor released him from the guild laws in 1587. After his return to
Poland in 1590 he was employed by King Sigismund III Vasa and worked in
Kraków and
Warsaw. He also traveled to
Graz in 1595 to paint portraits of the family of
Archduke Charles II for Queen
Anne of Austria. Kober died in Kraków or Warsaw. ==Work==
