Arthorius?
The early mediaeval legend of King Arthur most likely originates from the life of one Roman from Podstrana, an eminent military commander and governor of the province of Liburnia, buried in a lavish grave in the Roman Pituntium, today the village of St Martin. The original tombstone bearing the name of Lucius Artorius Castus and a list of his important military and political functions is today kept in the Church of St Martin.
