Saint Silvan was a Christian martyr who is believed to have lived during the fourth century. While historical details regarding his specific identity remain uncertain, he is associated with a skeleton currently housed in the Church of Saint Blaise in Dubrovnik. Some researchers suggest he might be the same individual as Silvanus, the Bishop of Emesa, who was martyred around 311. His remains have been kept in the Dubrovnik church since the middle of the 19th century.
