San Ciriaco de Camiliano  San Ciriaco de Camiliano was an ancient church of the city of Rome, formerly located on the present site of the Piazza del Collegio Romano near the Via del Corso (the ancient "Via Lata" of the Romans). It was demolished in 1491 during construction on the church of Santa Maria in Via Lata. San Ciriaco was located near the Via Lata, not far from the so-called "arcus Diburi", which was afterwards called the "Camilianum." Mariano Armellini describes the "arcus Diburi" as an ancient arch surmounted by the tower, which was believed to be an entrance to a Roman monument called the "Diribitorium", a large building begun by Agrippa, and finished by Augustus. It was apparently used to count votes and distribute salaries to the Roman militias, and its name derives from the "diribitores," or election officials. It burned under Titus, together with the adjacent Iseum. By the Middle Ages, the old name of the arch had been lost in common parlance, and it was called "arco maggiore" ("large arch") or the "arco di Camillo" (although according to Christian Hülsen that name was more the result of mistaken scholarship in the sixteenth century than an indication that the site was ever associated with someone named Camillus). The arch was eventually named the Camillianum, which was applied to the neighborhood, and by extension, the church of San Ciriaco. Its dedication was to Saint Cyriacus, a Roman martyr of the Diocletianic Persecution, whose relics were kept in the church. The origins of the church are underhood to be quite ancient, although Armellini notes that the tradition of it dating back to the time of Pope Sylvester is not quite worthy of belief. The church had a substantial connection to Cyriacus himself. His bodies, along with those of his two martyred companions, Largus and Smaragdus, were brought to Rome at the beginning of the fourth century. Their original resting place was near the Porta Salaria. From there they were moved to a cemetery near the Via Ostiensis, and finally, in about the tenth century to transferred — not to the church named after him, but to the church of Santa Maria in Via Lata. In 1491, Pope Innocent VIII ordered a complete reconstruction and expansion of the church of Santa Maria in Via Lata, which required the church of San Ciriaco to be demolished.
