This mural shows what Emperor Diocletain’s retirement home looked like when it was built in the 4th century on ten acres in Spalato, now called Split. Surprising, many of the original walls surrounding the opulent Roman palace are still standing. The figure wearing the mitre is Saint Domnius. He was the Bishop of Salona until he was martyred by the emperor in 304 AD. In his left hand is the city of Split.
