A duck swims on the Rhine River. It is said that when Jan Hus was about to expire, he cried out, 'Christ, son of the Living God, have mercy on us!' Hus' ashes were later thrown into the Rhine River. Jan Hus (or John Huss, 1369 - 1415) was a Czech priest, philosopher and one of the first church reformers. Hus attacked moral failings among the clergy and promoted some of the teachings of John Wycliffe (1331 - 1384), an English reformer who had been burned at the stake in 1384. Hus was excommunicated for his views in 1410 and burned at the stake as a heretic in Konstanz on 6 July 1415.
