Res Gestae

Now Licinius was a native of New Dacia, and was of somewhat common origin. He was made emperor[*](I.e., Augustus; see Introd. to Vol. I, p. xxv. He seems never to have been a Caesar.) by Galerius, in order that he might take the field against Maxentius. But when Maxentius was overthrown and Constantine had recovered Italy, he made Licinius his colleague on condition that he should marry Constantine’s sister Constantia at Mediolanum. After the celebration of the wedding Constantine went to Gaul, and Licinius returned to Illyricum.

Some time after that Constantine sent Constantius[*](His son, the future emperor, Constantius II.) to Licinius, to persuade him to confer the rank of Caesar on Bassianus, who was married to a second sister of Constantine (named Anastasia), to the end that, after the manner of Maximianus, Bassianus might hold Italy and thus stand as a buffer between Constantine and Licinius.

But Licinius thwarted such an arrangement, and influenced by Bassianus’ brother Senicio, who was loyal to Licinius, Bassianus took up arms against Constantine. But he was arrested in the act of accomplishing his purpose, and by order of Constantine was condemned and executed. When the punishment of Senicio was demanded as the instigator of

Their armies were led to the plain of Cibalae.[*](Cf. Amm. xxx. 7, 2.) Licinius had 35,000 infantry and cavalry; Constantine commanded 20,000. After an indecisive contest, in which 20,000 of Licinius’ foot soldiers and a part of his mail-clad horsemen were slain, he himself with a great part of his other cavalry made his escape under cover of night to Sirmium.
