5 Hymnes - III. Auctor Beate

Jean-Yves Daniel-Lesur, known often simply as Daniel-Lesur (November 19, 1908 – July 2, 2002) was a French organist and composer.

A student of Tournemire, in 1935 he became professor of counterpoint at the Schola Cantorum under its new director, Nestor Lejeune.

The following year he co-founded the group La Jeune France along with composers Olivier Messiaen (with whom he would remain a lifelong friend), André Jolivet and Yves Baudrier, who were attempting to re-establish a more human and less abstract form of composition. La Jeune France developed from the avant-garde chamber music society La spirale, formed by Jolivet, Messiaen, and Daniel-Lesur the previous year.

That same year he, together with Jean Langlais and Jean-Jacques Grunenwald, gave the first performance of Olivier Messiaen's La Nativité du Seigneur.

Daniel-Lesur also served as director of the Opéra National de Paris from 1971 to 1973.

Auctor Beate - This hymn is of unknown authorship and date. It is for the Feast of the Sacred Heart of Jesus; for which Feast in some editions of the Roman Breviary later than 1735 there are two distinct offices with different hymns; the day of observance being that following the Octave of Corpus Christi (viz. Friday before the 3rd Sunday after Whitsunday). Auctor beate saeculi is the hymn at second Vespers in the first office when the Feast is kept on its own day, and with the rank of a greater double; and at both Vespers when the Feast is transferred, or kept with the rank of a double of the first or second class, the reason being that in the former case the first Vespers are superseded by the second Vespers of the Octave of Corpus Christi. In England the first office is appointed to be said on the Sunday after the Octave of Corpus Christi, with the rank of a double of the second class; religious orders, as a rule, observing it on the Friday succeeding that Octave, thus the hymn occurs at both Vespers.
