Baring-Gould’s sources: Greek Menaea and Menology, and Roman Martyrology. Authority: — The Ancient Greek Acts, when written is not very clear. They are probably based on the records of the notaries who took down the words used at the trial and the sentence. That Julian should have executed ambassadors is more than improbable, and this almost wholly discredits the Acts.] The king of Persia sent three Christian young men named Manuel, Sabiel, and Ismael, sons of a favourite Magian, to Julian the Apostate, with a letter, shortly before the great Persian war broke out, in which Julian lost his life. They were received with courtesy by Julian, and he bade them attend him in his course through Bithynia. At Chalcedon the arrival of the emperor was the signal for a great Pagan demonstration When the three Persian ambassadors saw the stream of people flowing into the temple, they beat their breasts with grief. The chamberlain of the king, an Indian, invited them to enter and assist at the sacrifice, but they indignantly refused. Julian was greatly exasperated at their conduct, when it was reported to him, and ordered their execution, and that their bodies should be burnt. When the Persian king heard of the death of his ambassadors he was highly incensed, and this was one of the causes of the war breaking out which terminated fatally to Julian.
