Pange Lingua

Pange Lingua is a hymn written by St. Thomas Aquinas (1225-1274) for the Feast of Corpus Christi (now called the Solemnity of the Holy Body and Blood of Christ). Some writers feel that the rhythm was based on the marching song of Caesar's Legions: "Ecce, Caesar nunc triumphat qui subegit Gallias." It is also used on Holy Thursday when the last two stanzas, called separately Tantum Ergo, are sung at Benediction of the Blessed Sacrament. Both the hymn and liturgical observances celebrate a transubstantiation where the bread and wine is believed in faith to be changed into the Body and Blood of Christ.

In supremae nocte coenae	On the night of that Last Supper,
recumbens cum fratribus		seated with His chosen band,
