The relics of the Palestinian
martyr, who died during the reign of the Emperor Diocletian, had been kept in the
Episcopal Church of St. Procopius all the time until 1072. That year, in one of their
military campaigns, the Hungarian army took the arm of the Saint to the Church of St.
Dimitrios in Sremska Mitrovica. Upon the order of the Emperor Manuel I Comnenus, the arm
was returned to Niš and attached to the rest of the relics. The relics of St. Procopius
had stayed in Niš, as he was the patron saint of the city, until the invasion of Turks,
when they were transferred to Prokuplje, the town that was named after him.
