April 22, 1418: The Council of Constance ends, having finally ended the Great Western Schism. When the schism began nearly 40 years earlier, three men had reasonable claims to the papacy. The council deposed all three and elected Martin V. (Martin then turned around and rejected further councils' right to depose a pope.) Though that part of the council is regarded as a triumph, the council also hastily condemned Jan Hus, a Bohemian preacher and forerunner of Protestantism, and sentenced him to execution by burning. And since his teachings were based on those of John Wycliffe (c. 1329-1384), the council had the Bible translator's body dug up, burned, and thrown into the Swift River (see issue 68: Jan Hus).
April 22, 1724: German philosopher Immanuel Kant, a pivotal figure in the history of modern philosophy and theology, is born in Konigsberg, East Prussia.
April 22, 1669: Colonial religious leader Richard Mather (father of Increase, grandfather of Cotton) dies at age 63. He helped author the Bay Psalm Book and the Cambridge Platform, which served for many years as the standard doctrinal statement for New England Congregationalism (see issue 41: American Puritans).
April 22, 1864: The motto "In God We Trust," conceived during the Civil War, first appears on American coinage.
May 16, 583 (traditional date): Brendan the Navigator, founder of a Celtic monastery in Clonfert, Ireland, dies. Some Irish scholars have asserted that Brendan was among the first Europeans to reach America, nine centuries before Columbus (see issue 60: How the Irish Were Saved).
May 16, 1805: Henry Martyn, a well-educated Englishman, arrives in India to aid William Carey with translation work (see issue 36: William Carey).
