St. Martina

She was a noble Roman virgin, who glorified God, suffering many torments and a cruel death for her faith, in the capital city of the world, in the third century. There stood a chapel consecrated to her memory in Rome, which was frequented with great devotion in the time of St. Gregory the Great. Her relics were discovered in a vault, in the ruins of her old church and translated with great pomp in the year 1634, under the Pope Urban VIII, who built a new church in her honor, and composed himself the hymns used in her office in the Roman Breviary. The city of Rome ranks her among its particular patrons. The history of the discovery of her relics was published by Honoratus of Viterbo, an Oratorian.
