and retire to his cabbage-garden at Dyrrhachium.
Maximian found himself unwillingly obliged to retire likewise; and the
two Caesars, Galerius and Constantius, became, by the operation of the
new constitution, _ipso facto_ Augusti.

A. 13.--But already the mutual jealousy and distrust in which that
constitution was so soon to perish began to manifest themselves.
Galerius, though properly only Emperor of the East, seized on Rome,
and with it on the person of the young Constantine, whom he hoped
to keep as hostage for his father's submission. The youth, however,
contrived to flee, and post down to join Constantius in Gaul,
slaughtering every stud of relays along the entire road to delay his
pursuers. Both father and son at once sailed for Britain, where the
former shortly died, like Severus, at York. With their arrival the
persecution promptly ceased;[332] for Helena, at least, was an ardent
Christian, and her husband well-affected to the Faith. Yet, on his
death, he was, like his predecessors, proclaimed _Divus_; the last
formal bestowal of that title being thus, like the first,[333]
specially connected with Britain. Constantius was buried, according
to Nennius,[334] at Segontium, wherever that may have been; and
Constantine, though not yet even a Caesar, was at once proclaimed by
the soldiers (at his native York) Augustus in his father's room.

A. 14.--This was the signal for a whole outburst of similar
proclamations all over the Roman world, Licinius, Constantine's
brother-in-law, declared himself Emperor at Carnutum, Maxentius,
son of Maximian and son-in-law of Galerius, in Rome, Severus in the
Illyrian provinces, and Maximin (who had been a Caesar) in Syria.
Galerius still reigned, and even Maximian revoked his resignation
and appeared once more as Augustus. But one by one this medley of
Pretenders swept each other away, and the survival of the fittest was
exemplified by the final victory of Constantine over them all. For
a few years he bided his time, and then, at the head of the British
army, marched on Rome. Clear-sighted enough to perceive that events
were irresistibly tending to the triumph of Christianity, he declared
himself the champion of the Faith; and it was not under the Roman
Eagle, but the Banner of Christ,[335] that his soldiers fought and
won. Coins of his found in Britain, bearing the Sacred Monogram which
led his men to the crowning victory of 312 at the Milvian Bridge (the
intertwined letters [Gre
