Saint Helen, the mother of Saint Constantine the Great, when she was already advanced in years, undertook, in her great piety, the hardships of a journey to Jerusalem in search of the cross, about the year 325. A temple to Aphrodite had been raised up by the Emperor Hadrian upon Golgotha, to defile and cover with oblivion the place where the saving Passion had been suffered. The venerable Helen had the statue of Aphrodite destroyed, and the earth removed, revealing the Tomb of our Lord, and three crosses. Of these, it was believed that one must be that of our Lord, the other two of the thieves crucified with Him; but Saint Helen was at a loss which one might be the Wood of our salvation. At the inspiration of Saint Macarius, Archbishop of Jerusalem, a lady of Jerusalem, who was already at the point of death from a certain disease, was brought to touch the crosses, and as soon as she came near to the Cross of our Lord, she was made perfectly whole. Consequently, the precious Cross was lifted on high by Archbishop Macarius of Jerusalem; as he stood on the ambo, and when the people beheld it, they cried out, "Lord have mercy." It should be noted that after its discovery, a portion of the venerable Cross was taken to Constantinople as a blessing. The rest was left in Jerusalem in the magnificent church built by Saint Helen, until the year 614. At that time, the Persians plundered Palestine and took the Cross to their own country (see Jan. 22, Saint Anastasius the Persian). Late, in the year 628, Emperor Heraclius set out on a military campaign, retrieved the Cross, and after bringing it to Constantinople, himself escorted it back to Jerusalem, where he restored it to its place.

The holy Martyr Eustathius before his baptism was an illustrious Roman general named Placidas in the days of the Emperor Trajan. While hunting in the country one day, he was converted to the Faith of Christ through the apparition of an uncommonly majestic stag, between whose antlers he saw the Cross of Christ, and through which the Lord spoke to him with a human voice. Upon returning home, he learned that his wife Tatiana had also had a vision in which she was instructed to become a Christian. They sought out the Bishop of the Christians and were baptized, Placidas receiving the name Eustathius, and Tatiana the name Theopiste; their two sons were baptized Agapius and Theopistus. The family was then subjected to such trials as Job endured. Their servants died, all their goods were stolen, and on a pilgrimage to Jerusalem they were scattered abroad, each not even knowing if the others were still alive. By the providence of God, they were united again after many years, and returned to Rome in glory. Nevertheless, when they refused to sacrifice to the idols-a public sacrifice from which no Roman general could be absent-the Emperor Hadrian, who had succeeded Trajan, had them put into a large bronze device in the shape of a bull, which was heated with fire until they died. When their holy bodies were removed, they were found to be without harm. They suffered martyrdom about the year 126.
