Prior to the revision of the Breviary and liturgical calendar instituted by Pope St. Pius XII, the Octave of Our Holy Father St. Dominic would be celebrated today, August 11. This would be the final act in our long celebration of the feast of St. Dominic. A fitting tribute to the saintly founder of the Order of Preachers, if I do say so myself. When you add up all of the preparation (the 15 Tuesdays, the Novena, the feast itself, the commemoration in the octave, and finally, the octave day itself) it is a sure and salutary means of developing a loving devotion to our holy father through our liturgical celebrations.
In the pre-1962 Breviarium S.O.P.'s, the feast had the rank of "solemne", which would be considered at least a 2nd Class Feast in the ranking system that was adopted with the 1962 breviary. For Lauds, Vespers, and the little hours, the office of the feast was prayed. At Lauds, a commemoration was made of St. Tiburtius. At Matins the office was that of three (3) lessons. For the first nocturn, the responsories are proper, and the lessons from the previous Sunday are used. At the second nocturn, the lessons and the responsories are proper; the lessons being taken from the life of St. Dominic by Theodoric. The third nocturn is like the first, with the responsories being proper, but the Gospel and homily on the Gospel are taken from the previous Sunday.

At Pretiosa, on August 10, the octave was announced thus "The Octave day of our holy Father Dominic. A solemn octave."
I am going to depart from my 1962/1967 calendar today, since it is a ferial day, and pray the office of his feast again, as a way of closing out this wonderful liturgical celebration of St. Dominic.
