The Roman general, Gallicanus, having been in favour with the Emperor, and having lost his wife, was offered Constantia in marriage by his master—not a particularly inviting proposal, and Gallicanus did not, possibly, regret that he was called away by an inroad of the barbarians into Thrace, to defend the Roman frontiers against them. Before engaging in battle he made a vow, in the event of success, that he would believe in Christ and be baptised. He succeeded in repulsing the enemy, and returned to Rome to find that Constantia had been healed of her disorder at the tomb of S. Agnes, and that she had persuaded his three daughters, Augusta, Attica, and Artemia, to live with her, as consecrated virgins, near the shrine of the Virgin Martyr, to whose intercession she attributed her cure. Constantia had two chamberlains, John and Paul, to whom, at her death, she bequeathed much of her possessions. When Julian the Apostate assumed the purple, in 361, he did not openly persecute the Church, but he turned out of their situations such officers of the court and army as refused to renounce Christ. John and Paul he particularly disliked, partly because they were zealous Christians, and had had much to do with the conversion of Gallicanus, but also because they had obtained by bequest so much of Constantia’s estate, which he desired to draw into the imperial treasury. He sent word that they were to be deprived of their offices, and were to be privately put to death in their own house. Accordingly, when they had retired to their residence on the Cœlian Hill, the ministers of Julian pursued them, dismissed the servants, and secretly conveyed them down into the cellar of their palace, and there killed and buried them. Three persons, however, knew of what was going on—Crispinus, Crispinianus, and Benedicta—and, to prevent the matter getting bruited about, these the soldiers also put to death. Gallicanus was living at Ostia, and he was ordered into exile. He withdrew to Alexandria, where the chief magistrate, Baucianus, summoned him before his tribunal, required him to do sacrifice to idols, and, because he refused, had him decapitated. He has found a place in the Roman Martyrology on June 25th. Now the whole series of incidents is full of difficulties. The name of Gallicanus was not uncommon. Vulcatius Gallicanus was prefect of Rome in 317, and Ovius Gallicanus was Consul in 330, but of either of them being engaged against the barbarians in Thrace there is no historical evidence. It is also incredible that the Gallicanus of the legend should have been publicly tried as a Christian and condemned as such under Julian.
