The Ave Maria (Hail Mary) is one of the oldest and most popular Catholic prayers. Of unknown origin, it was not officially incorporated into the liturgy (as part of the Rosary) until the 15th Century.
AVE Maria, gratia plena, Dominus tecum. Benedicta tu in mulieribus, et benedictus fructus ventris tui, Iesus. Sancta Maria, Mater Dei, ora pro nobis peccatoribus, nunc, et in hora mortis nostrae. Amen.
HAIL Mary, full of grace, the Lord is with thee. Blessed art thou amongst women and blessed is the fruit of thy womb, Jesus. Holy Mary, Mother of God, pray for us sinners, now, and in the hour of our death. Amen.
