It's the Feast of Ss. Peter and Paul today, which is a very great thing. Several verses from the Decora Lux, based on Boethius' wife's 5th century poem, are sung today if you have a Schola, I don't, annoyingly. English translation by Dom Gueranger, OSB:
Aurea luce et decore roseo,
Lux lucis, omne perfudisti sæculum:
decorans cælos inclito martyrio.
Hac sacra die, quæ dat reis veniam.
O Light of light (Jesus), thou hast inundated every age with a golden light and with a ruddy beauty, adorning the heavens with a glorious martyrdom, on this sacred day, which gives pardon to the guilty.
Janitor cæli, doctor orbis pariter,
Judices sæcli, vera mundi lumina:
Per crucem alter, alter ense triumphans,
Vitæ senatum laureati possident.
The door-keeper of heaven, as also the teacher of the universe, the judges of the world, the true lights of the earth, the one conquering by the cross, the other by the sword, crowned with laurel, both take their seats in the senate of life.
Peter and Paul, pray for us,
