Conversion and Monastic Life
According to the synaxarion, Dometius lived in Persia in the fourth century and was converted to the faith by a Christian named Uaros. He afterward left Persia for Nisibis in Mesopotamia, where he received baptism and took monastic vows.
He later joined the monastery of Saints Sergius and Bacchus in Theodosiopolis, governed by the austere archimandrite Urbelos. Ordained a deacon, he fled to a remote Syrian mountain near Cyrrhus rather than accept ordination to the priesthood.
From his mountain refuge he attracted followers and was known for working miracles. Many pagans were brought to faith in Christ through him, and people sought him out for healing and spiritual guidance. He lived with two disciples who shared his ascetic life.
Martyrdom
The martyrdom took place during the Persian campaign of the Emperor Julian the Apostate (361–363). Soldiers discovered Dometius and his companions at prayer in a cave, and by imperial order they were put to death there.
The accounts differ on the precise manner of death. The anchor tradition records that he and his two disciples were stoned to death in the cave, which aligns with the description of his death as lapidation (stoning). The Orthodox synaxarion instead relates that they were walled up alive inside the cave. The two disciples are not named individually in the sources.
Veneration and Legacy
Dometius is commemorated on August 7; some sources also give the date as August 8. He is invoked against sciatica.
The name Dometius (Domitius) appears three times in the Roman Martyrology on different feast days — August 7, March 23, and July 5 — and it is uncertain whether these refer to the same person.
He was depicted in an eighth-century fresco in the Church of Santa Maria Antiqua in Rome, alongside Saints Barachisius, Euthymius, and Sabas of Palestine, evidence that suggests the presence of Greek-speaking monks at Santa Maria Antiqua. He is to be distinguished from the Venerable Dometius of Philotheou on Mount Athos, who is also commemorated on August 7.
