(Hail, thou Star of Ocean.)
The first verse of an unrhymed, accentual hymn, of seven stropes of four lines each, assigned in Roman Breviary to Vespers in the Common office, the Office of Saturdays, and the Little Office (as well as for Feasts) of the Blessed Virgin. It has been ascribed wrongly to St. Bernard, but antedates him, being found in a St. Gall manuscript of the ninth century; and also, without sufficient authority, to St. Venantius Fortunatus (d. 609). Its frequent occurence in the Divine Office made it most popular in the Middle Ages, many other hymns being founded upon it.
