Adon Olam is a piyyut that became popular in the 15th century and is often attributed to Solomon ibn Gabirol (1021–1058) and less often to Sherira Gaon (900-1001), or his son, Hai ben Sherira Gaon (939-1038). The variation of the piyyut appearing here is the 12 line version familiar to Sepharadi congregations. (There are also fifteen and sixteen line variants found in Sepharadi siddurim. The Ashkenazi version has ten lines.) The rhyming translation here by Jacob Waley was transcribed from the prayerbook of his daughter Julia M. Cohen’s The Children’s Psalm-Book (1907), pp. 298-299. . . .
