Wülffer, Daniel—1617-1685—born at Nuremburg, a professor and minister in that city. The hymn “O Ewigkeit, O Ewigkeit,” is a serious and pious consideration of, and apostrophe to, Eternity, which in the last verse replies to man. The first seven verses, as far as the words “O lange Freud, O langes Leid,” Wülffer found in an old hymn-book, perhaps the Catholic hymn-book of Cologne; he improved them, and added the spirited conclusion.
