Saint Domnius
Bishop of Salona
Saint Domnius (also known as Saint Dujam or Saint Duje, Saint Domnio, Saint Doimus, or Saint Domninus) was a Bishop of Salona (today's Solin) around the year 300, and is venerated as the patron of the nearby city of Split in modern Croatia.
Traditional narrative
Christian tradition states that he was one of the Seventy Disciples of the 1st century. This tradition holds that Domnio came to Rome with Saint Peter and was then sent by Peter to evangelize Dalmatia, where he was martyred along with eight soldiers he had converted.
He was more likely a martyr of the 4th century. He was born in Antioch, (in modern-day Turkey but historically in Syria), to a prominent and wealthy family. He was educated at the university there. Domnius became bishop of Salona around 284, and was later beheaded 10 April 304 at the amphitheatre in Salona, a large Roman city serving as capital of the Province of Dalmatia. Saint Domnius was martyred with seven other Christians in the persecutions of the Emperor Diocletian, and was buried in the Manastirine cemetery, outside the walls of Salona.
Veneration
When Salona was sacked by the Avars and Slavs in the 6th century, the population eventually moved to the nearby Palace of Diocletian, enlarging the nearby city of Split (Spalatum), and establishing it as the successor to Salona. Saint Domnius became the city's patron saint, and the city's Cathedral of Saint Domnius was built in the mausoleum of Diocletian itself, the emperor who martyred him.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q387986. VIAF identifies the subject as 1736049. The Library of Congress control number is n96057983. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
