"At Rome, at Aquae Salviae, St. Anastasius, a Persian monk, who, after suffering much at Caesarea, in Palestine, from imprisonment, stripes and fetters, had to bear many afflictions from Chosroes, king of Persia, who caused him to be beheaded. He had sent before him to martyrdom seventy of his companions, who were precipitated into rivers. His head was brought to Rome, together with his venerable likeness, by the sight of which the demons are expelled, and diseases cured, as is attested by the Acts of the second council of Nicaea."[7]
"AT Valencia, in Spain, while the wicked Dacian was governor, St. Vincent, deacon and martyr, who, after suffering imprisonment, hunger, the torture, the disjointing of his limbs; after being burned with plates of heated metal and on the gridiron, and tormented in other ways, took his flight to heaven, there to receive the reward of martyrdom. His noble triumph over his sufferings has been elegantly set forth in verse by Prudentius, and highly eulogized by St. Augustine and pope St. Leo."[7]
"St. Gregory of Peć (17th-18th C.) was a young monk of the monastery of the Patriarchate of Peć. He was martyred after refusing to convert to Islam. Miracles began to take place at the place where he was secretly buried by faithful Christians and a small church was later built on the site. Atheist authorities demolished the church and built an institute in the mid-20th century, although the martyr’s incorrupt relics were discovered during the demolishing of the church. His memory will be celebrated on January 22/February 7."[22]
