martyr. His ancient cult is witnessed by a 6th century mosaic representation with the inscription ‘Scs Iustus’. His church was rebuilt in the 11th century and joined onto the adjacent cathedral. His Acts tell us that he was a Christian from childhood, devoted to penance and almsgiving, in the time of Diocletian and Maximian. The local prefect Manaccius told him with a threat of death that he had to obey the imperial edicts. Justus defended his faith with firm serenity. He was then condemned to be thrown into the sea with lead weights tied to his arms and legs. His body was later washed up on the shore and buried by a priest named Sebastian.
A cathedral inventory of 1040 records that his body was still kept there; in 1624 these relics were inspected and approved. Justus is still the patron both of the cathedral and of the city of Trieste. A fine 14th-century statue of him adorns the cathedral campanile. Feast: 2 November.
