Wycliffe's Ashes

From Wikipedia:

The Council of Constance declared Wycliffe a heretic on 4 May 1415, and banned his writings, effectively both excommunicating him retroactively and making him an early forerunner of Protestantism. The Council decreed that Wycliffe’s works should be burned and his bodily remains removed from consecrated ground. This order, confirmed by Pope Martin V, was carried out in 1428.^[7] Wycliffe’s corpse was exhumed and burned and the ashes cast into the River Swift, which flows through Lutterworth.
