In art, he appears with the pontifical tiara and a dove. S. SEBASTIAN, M., AT ROME. (A.D. 303.) [All the ancient Latin Martyrologies. The Greeks commemorate him on December 18th. The original Acts are not in our possession. What is regarded as the Acts appears to be a panegyric, falsely attributed to S. Ambrose, on S. Sebastian's Day. The incidents are no doubt taken from the original Acts, but the long sermons and theological instructions put into the mouths of S. Sebastian and Tranquillinus, are certainly oratorical compositions of the author who passes for S. Ambrose.] S. Sebastian was born at Narbonne, in Gaul, but his parents were of Milan, in Italy, and he was brought up in that city. He was a fervent soldier of Christ at the same time that he served in the army of the Emperor. He was so greatly regarded by the Emperors Diocletian and Maximian, that he was elevated to the command of the first cohort, for he was a man prudent, upright in word and act, faithful in business, fervent in spirit. He was enabled, by his rank and office, to be of service to those who were imprisoned for the faith of Christ. He relieved their sufferings, and urged them to constancy. Two brothers, Marcus and Marcellianus, had been accused of being Christians, and were expecting execution in prison, when their friends, admitted to see them, implored them with tears to save their lives by apostasy. They seemed to waver; they promised to deliberate. Sebastian heard of this, and rushed to save them. He was too well known to be refused admittance, and he entered their gloomy prison as an angel of light. Tranquillinus, the father of the two youths, had obtained from Agrestius Chromatius,[94] prefect of the city, a respite of thirty days for them, to try their constancy; and, to second his efforts, they had been placed in the house of Nicostratus, the keeper of the records (_primiscrinius_). Sebastian's was a bold and perilous office. Besides the two Christian captives, there were gathered in the place sixteen heathen prisoners; there were the parents of the unfortunate youths weeping over them, to allure them from their threatened fate; and there was the magistrate, Nicostratus, with his wife Zoë, drawn thither by the compassionate wish of seeing the youths snatched from their fate. Could Sebastian hope that of this crowd not one would be found whom a sense of official duty, or a hope of pardon, or hatred of Christianity, might impel to betray him, if he avowed himself a Christian?
