The Aeterna Christi munera is the oldest of the hymns In natali martyrum, and so is the source and inspiration of all other hymns for martyrs. We have set the original verses of this hymn to two Dominican melodies.
From the Liturgical Year, Gueranger
“St Peter Damien has consecrated a hymn to the doctor of the Gentile in strains of energetic piety.”
N.B. We have not found an original melody for this hymn so have set this to an Ambrosian melody.
The following hymns have been found in the Analecta Hymnica,
Georgii militia, Matins Hymn from the Analecta Hymnica Vol.43 Hymn. ms. S. Petri Mart. Utinen. saec. 16. Cod. Civit. Utinen.
Salve festa Dies, Georgi, Processional Hymn for the Feast of St. George, from Analecta Hymnica Vol 43. Process. ms. Londinense ann. 1413-1422. Cod. Oxonien. Lat. Lit. e 7. Abschrift von Rev. H. M. Bannister.
