From the St. Vitus Cathedral#

Jan Cec came from the branched house of the governor of Yichin, holding the courtyard and the fort of Nemyceves. He slaved the reign of Vladislav II. Jagellon in Prague Castle until his death, just like his brother Vaclav. His duty in the Royal Court was not only to pour wine, but also to taste it, if it was not annoyance, and to keep the street and the company on the roads. The coat of graves is similar to a ragged raven.
