Gloria, Laus et Honor is a Christian hymn composed and written by Theodulf of Orléans between 810 and 817, and sung as a processional for Palm Sunday, based on the story of Jesus's arrival in Jerusalem before his passion and death. It was most likely composed by Theodulph of Orléans in the early ninth century.[1] The modern English hymn "All Glory, Laud and Honour" is based on a translation of this text.
