Jan Hus is condemned by the assembly of the council in the Konstanz Cathedral as a heretic and sentenced to be burned at the stake.

Jan Hus, sometimes anglicized as John Goose or John Huss, and referred to in historical texts as Iohannes Hvs or Johannes Huss, was a Czech theologian and philosopher who became a Church reformer and the inspiration of Hussitism, a key predecessor to Protestantism, and a seminal figure in the Bohemian Reformation. Hus is considered to be the first Church reformer, even though some designate the theorist John Wycliffe. His teachings had a strong influence, most immediately in the approval of a reformed Bohemian religious denomination and, over a century later, on Martin Luther.

Konstanz Minster or Konstanz Cathedral is a historical building in Konstanz, southern Germany, the proto-cathedral of the former Roman Catholic diocese of Konstanz.
