anger and one which did not manifest itself so long as
Diocletian remained at the helm. Writers have been very free of their
censure upon this emperor for parcelling, as they call it, the Empire;
but this was the only chance there was of preventing its crumbling to
pieces. Italy, and Rome in particular, lost by the change: they no
longer monopolized the wealth and power of the world, but the other
provinces gained. The Empire was much too large for one single man or
a single central administration, under the dwindled influence of the
Roman name, and amidst the numerous causes of local dissension and
discontent, private ambition, social corruption, and foreign
hostility, that had accumulated for three centuries, since the time of
Augustus.

The new Caesars justified Diocletian's expectations. Constantius
defeated the Franks and the Alemanni, and soon after reconquered
Britain. Galerius subjugated the Carpi, and transported the whole
tribe into Pannonia. In the year 296, the Persians, under their king
Narses, again invaded Mesopotamia and part of Syria. Galerius marched
against them, but being too confident was defeated by superior
numbers, and obliged to retire. On his meeting Diocletian, the emperor
showed his dissatisfaction by letting Galerius walk for a mile, clad
in purple as he was, by the side of his car. The following year
Galerius again attacked the Persians, and completely defeated them,
taking an immense booty. The wives and children of Narses, who were
among the prisoners, were treated by Galerius with humanity and
respect. Narses sued for peace, which was granted by Diocletian on
condition of the Persians giving up all the territory on the right or
western bank of the Tigris. This peace was concluded in 297, and
lasted forty years.
At the same time Diocletian marched into Egypt against Achillaeus, whom
he besieged in Alexandria, which he took after a siege of eight
months, when the usurper and his chief adherents were put to death.
Diocletian is said to have behaved on this occasion with unusual
sternness. Several towns of Egypt, among others Busiris and Coptos,
were destroyed. Constantine, the son of Constantius, who was educated
at Nicomedia, accompanied the emperor in this expedition. Diocletian
fixed the limits of the Empire on that side at the island of
Elephantina, where he built a castle, and made peace with the
neighboring tribes, called by some Nubae and by
