Although the sequence had apparently occupied the center of attention, the writing of office and festival hymns had never been interrupted and certainly had never ceased. Gathering up the sources after the period of ninth century influence described in Chapter Three, one pauses at the verse of Peter Damian, (988-1072), Cardinal Bishop of Ostia and Superior of the monks of the Holy Cross. His theme was the joys of paradise in the hymn _Ad perennis vitae fontem_, “To the fount of life eternal,” a topic about which a distinguished hymnody was ultimately created. (See Illustrative Hymns, XIV. _Ad perennis vitae fontem_, “To the fount of life eternal.”) Fulbert, Bishop of Chartres (d. 1028), is best known for his Easter hymn, _Chorus novae Ierusalem_, “The chorus of the New Jerusalem,”[5] in which the militant ideal in its knightly form finds expression as the warriors of the faith acclaim the victory of their royal and divine leader. In the twelfth century, a complete new hymnary in all its parts was written by Abelard, (1079-1142), for the Convent of the Paraclete of which Heloise was the abbess.[6] A collection of 91 hymns, it has never been highly praised by critics, yet it has provided the hymn, _O quanta qualia_, “How mighty are the Sabbaths,” in praise of the Sabbath and the Good Friday hymn, _Solus ad victimam procedis, Domine_, “Alone to sacrifice Thou goest, Lord,” both of which have found a place in recent hymnals. Helen Waddell’s translations of the two illustrate modern renderings at their best. The same century saw the achievement of Bernard of Cluny or Morlaix, (fl. 1122), whose long poem, _De contemptu mundi_ furnished the selections on the heavenly country, _Hora novissima_, popularized by the translations of John Mason Neale. Perhaps the best-known of these, _Urbs Sion aurea_, “Jerusalem the Golden,” in its English rendering has attained a vernacular status independently of its Latin original. The great anonymous hymn, _Jesu dulcis memoria_, “Jesu, the very thought of Thee,” is also of the twelfth century. Its authorship has been variously ascribed but never certainly determined.
