Pange lingua may refer to either of two Mediaeval Latin hymns of the Roman Catholic Church: one by St. Thomas Aquinas and one by Venantius Fortunatus (530-609), which extols the triumph of the Cross. He wrote it for a procession that brought a part of the true Cross to Queen Radegunda in 570. This hymn is used on Good Friday during the Adoration of the Cross and in the Liturgy of the Hours during Holy Week and on feasts of the Cross. The concluding stanza was not written by Fortunatus, but was added later.When used in the Liturgy the hymn is often broken into smaller hymns such as: Lustra sex qui iam peregit, En acetum, fel, arundo, and Crux fidelis inter omnes.
