Conversion and Vision
Before his conversion, Placidas served as a Roman general during the reigns of the emperors Titus (79–81) and Trajan (98–117), distinguishing himself in arms and in charitable works on behalf of the poor.
The central episode of his life is the vision granted to him while hunting. As he pursued a stag, a cross is said to have appeared between its antlers, and a voice identified itself as that of Christ. According to the Orthodox life, the stag spoke the words, 'I have appeared here on this creature for your sake, to draw you into the net of my love for mankind.' His wife is reported to have received a prophetic dream the same night.
The family was baptized together by a Christian bishop. Placidas received the name Eustathios; his wife became Theopiste (also called Tatiana in some traditions); and their two sons were named Agapios and Theopistos. After baptism, the life relates that the Lord appeared to Eustathius again, warning him of sufferings to come.
Trials and Separation
Following his conversion, Eustathius lost his estates and wealth; his servants died of plague and his livestock perished. The family departed secretly and set out toward Egypt by sea.
During the voyage the ship's captain demanded to keep Theopiste as payment for passage, and Eustathius was forced ashore with his two sons. While crossing a river, one son was carried off by a lion and the other by a wolf; though Eustathius believed both lost, the life relates that they were rescued by shepherds and farmers nearby.
Eustathius then labored for several years as a field guard in obscurity, by the Orthodox account spending five years in a village (named Badessos in that tradition), believing his family gone.
Reunion and Recall to Command
The emperor Trajan summoned Eustathius back to military command. According to the Orthodox life, two former military acquaintances, Antiochos and Akakios, recognized him by a shoulder scar from a sword wound and restored him to his post.
Unknown to him, his own sons served as officers under his command. The life recounts that the two young men recognized one another while talking in their tent, and that Theopiste, who had been freed when the ship's captain died of disease, overheard and revealed herself. The family was thus reunited.
Martyrdom
After a military victory, the emperor Hadrian (reigned 117–138) demanded that the family offer sacrifice to the pagan gods. They refused, and the Orthodox life records Eustathius declaring, 'I am a Christian and I glorify and give thanks to Christ, and I offer sacrifice to Him.'
By the account of his life, the beasts loosed upon the family lay down at their feet and refused to harm them. Hadrian then ordered them enclosed alive within a heated brazen bull, where they died about the year 118.
The life relates that three days after the execution the bodies were found wholly unburned and their faces radiant, a sign that converted many witnesses. Before his death, Eustathius is said to have prayed for grace upon the relics of his family and for the protection of those who would invoke their names in peril at sea.
Veneration and Legacy
Eustathius is venerated in both the Eastern and Western traditions, with a shared feast on September 20. In the West he is counted among the Fourteen Holy Helpers.
An early medieval church dedicated to him in Rome is mentioned in a letter of Pope Gregory II. Abbot Suger records that the first relics of Eustathius in Europe were placed at an altar in the royal Basilica of Saint-Denis.
