division of their reputed relics. Their relics, deemed miraculous, were buried in the city of Cyrrhus in Syria. Churches were built in their honor by Archbishop Proclus and by Emperor Justinian I (527–565), who sumptuously restored the city of Cyrrhus and dedicated it to the twins, but brought their purported relics to Constantinople; there, following his cure, ascribed to the intercession of Cosmas and Damian, Justinian, in gratitude also built and adorned their church at Constantinople, and it became a celebrated place of pilgrimage. At Rome, Pope Felix IV (526–530) rededicated the Library of Peace (Bibliotheca Pacis) as a basilica of Santi Cosma e Damiano in the Forum of Vespasian in their honour. The church is much rebuilt but still famed for its sixth-century mosaics illustrating the saints. What are said to be their skulls are venerated in the Convent of Las Descalzas Reales of the Clares in Madrid, where they have been since 1581, the gift of Maria, daughter of Emperor Charles V. They had previously been removed from Rome to Bremen in the tenth century, and thence to Bamberg. Other skulls said to be theirs were discovered in 1334 by Burchard Grelle, Archbishop of Bremen. He "personally 'miraculously' retrieved the relics of the holy physicians Cosmas and Damian, which were allegedly immured and forgotten in the choir of the Bremen Cathedral. In celebration of the retrieval Archbishop and Chapter arranged a feast at Pentecost 1335, when the relics were translated from the wall to a more dignified place. Grelle claimed the relics were those Archbishop Adaldag brought from Rome in 965. The cathedral master-builder Johann Hemeling made a shrine for the relics, which was finished around 1420. The shrine, made from carved oak wood covered with gilt and rolled silver is considered an important mediaeval gold work. In 1649 Bremen's Chapter, Lutheran by this time, sold the shrine without the heads to Maximilian I of Bavaria. The two heads remained in Bremen and came into the possession of the small Roman Catholic community. They were shown from 1934 to 1968 in the Church of St. Johann and in 1994 they were buried in the crypt. The shrine is now shown in the Jesuit church of St Michael in Munich. At least since 1413 another supposed pair of skulls of the saints has been stored in St Stephens's Cathedral in Vienna. Other relics are claimed by the Church of
