Jan Tęczyński (1581–1637)

Jan Tęczyński (1581–1637), of the Topór coat-of-arms, was governor of Kraków (1620–37), Crown Cupbearer (czesnik koronny) from 1618, starosta of Płock, and owner of Tenczyn and Rytwiany.

In his youth Jan Tęczyński traveled throughout Europe and studied under Galileo.

He expanded the palace at Rytwiany, and his court was always open to writers and philosophers, such as Jan Andrzej Morsztyn, one of the most celebrated poets of the Polish Baroque.

Piotr Kochanowski dedicated to Tęczyński his translation of Torquato Tasso's Jerusalem Delivered.

His library and much of his wealth were inherited by the son-in-law of his brother Andrzej Tęczyński, Łukasz Opaliński, husband of Izabela, who was also a famous writer and patron of the arts and sciences.
