the approximate date of the "O Sacrum Convivium" chant
  • Has anyone on this list researched the origin of the chant antiphon for the Magnificat for Second Vespers of the Solemnity of the Body and Blood of Christ? It would have to be thirteen century but does anyone have any details of the first MSS of the antiphon?

    As the Office of Corpus Christi was composed by St Thomas Aquinas, most likely the first MS of this antiphon was St Thomas' sketch block.
