Saint Judas Cyriacus [Judah Kyriakos ] of Jerusalem (†d. ca. AD 366) was a Bishop of Jerusalem and a Christian martyr who assisted Saint Helena with the finding of the True Cross. He is said to the last in the desposynic line of Bishops of Jerusalem. After assisting Saint Helena with the finding of the True Cross, Judas Cyriacus was baptized, consecrated as bishop of Jerusalem, and martyred during the persecutions of Julian the Apostate. In the Acts of his martyrdom, he engages in a dialogue with the emperor Julian, and is described as suffering horrible torments. The Empress Galla Placidia is said to have presented Ancona with the relics of Judas Cyriacus. However, the saint's head was situated at Provins, which was brought over from Jerusalem by Henry I of Champagne, who built a church in this town to contain it. His feast is celebrated in the Eastern Orthodox Church on October 24 and in the Roman Catholic church on May 1 and 4.
