Marian

In the Leofric missal, there are four Marian feasts:

• The Purification (Fourth Century)
• The Annunciation (Seventh Century)
• The Assumption (Eighth Century)
• The Nativity (Seventh Century)

For the Purification, the mass is Suscepimus Deus. But for the Annunciation it is Rorate Coeli and the next two are virtually identical:

• Introit: Gaudeamus omnes/Eructavit (Assumption) & Gaudeamus omnes/Exultate iusti (Nativity)
• Gradual: Propter veritatem/Audi filia
• Alleluia: Adducentur
• Offertory: Ave Maria
• Communion: Dilexisti iustitiam

Clear signs of this schema are found in the old Roman mass for the Assumption

but is much less apparent in that for the Nativity.
