Composed by Saint Thomas Aquinas for the Office of Corpus Christi (see CORPUS CHRISTI, FEAST OF). Including the last stanza (which borrows the words “Genitori Genitoque”—Procedenti ab utroque, Compar” from the first two strophes of the second sequence of Adam of St. Victor for Pentecost) the hymn comprises six stanzas appearing in the manuscripts
Pange, lingua, gloriosi corporis mysterium,
Sanguinisque pretiosi quem in mundi pretium
Fructus ventris generosi Rex effudit gentium.
Written in accentual rhythm, it imitates the triumphant march of the hymn of Fortunatus, and like it is divided in the Roman Breviary into stanzas of six lines whose alternating triple rhyming is declared by Pimont to be a new feature in medieval hymnody. In the Roman Breviary the hymn is assigned to both Vespers, but of old the Church of Salisbury placed it in Matins, that of Toulouse in First Vespers only, that of Saint-Germain- des-Prés at Second Vespers only, and that of Strasburg at Compline. It is sung in the procession to the repository on Holy Thursday and also in the procession of Corpus Christi and in that of the Forty Hours’ Adoration.
