Feast of the Dedication of St Mary ad Martyres in Rome

Better known as the Pantheon, the ancient temple to the gods,  was purged by Pope St Boniface IV and consecrated in honour of Our Lady and all Holy Martyrs in the reign of the Emperor Phocas.

The Benedictines keep this Feast as the Commemoration of All Holy Martyrs and other Saints whose relics are conserved in their Churches. The Feast of All Saints became eventually to be celebrated on November 1st.
