Today's Ave Maria for peace is by Josquin Desprez (1440-1521). It's one of my favorite Ave Marias to sing and to listen to.
I think the last line is especially well done. The words , O Mater Dei, memento mei. Amen translate to, "Oh Mother of God, remember me. Amen." Listen to the way the music comes out like a prayer.
Indeed, he who sings, prays twice.
