The mind of Galerius was the most susceptible of the sterner passions, but it was not, however, incapable of a sincere and lasting friendship. Licinius, whose manners as well as character were not unlike his own, seems to have engaged both his affection and esteem. Their intimacy had commenced in the happier period perhaps of their youth and obscurity. It had been cemented by the freedom and dangers of a military life; they had advanced almost by equal steps through the successive honors of the service; and as soon as Galerius was invested with the Imperial dignity, he seems to have conceived the design of raising his companion to the same rank with himself. During the short period of his prosperity, he considered the rank of Cæsar as unworthy of the age and merit of Licinius, and rather chose to reserve for him the place of Constantius, and the empire of the West. While the emperor was employed in the Italian war, he intrusted his friend with the defence of the Danube; and immediately after his return from that unfortunate expedition, he invested Licinius with the vacant purple of Severus, resigning to his immediate command the provinces of Illyricum. 29 The news of his promotion was no sooner carried into the East, than Maximin, who governed, or rather oppressed, the countries of Egypt and Syria, betrayed his envy and discontent, disdained the inferior name of Cæsar, and, notwithstanding the prayers as well as arguments of Galerius, exacted, almost by violence, the equal title of Augustus. 30 For the first, and indeed for the last time, the Roman world was administered by six emperors. In the West, Constantine and Maxentius affected to reverence their father Maximian. In the East, Licinius and Maximin honored with more real consideration their benefactor Galerius. The opposition of interest, and the memory of a recent war, divided the empire into two great hostile powers; but their mutual fears produced an apparent tranquillity, and even a feigned reconciliation, till the death of the elder princes, of Maximian, and more particularly of Galerius, gave a new direction to the views and passions of their surviving associates.

When Galerius declared Licinius Augustus with himself, he tried to satisfy his younger associates, by inventing for Constantine and Maximin (not Maxentius; see Baluze, p. 81) the new title of sons of the Augusti. But when Maximin acquainted him that he had been saluted Augustus by the army, Galerius was obliged to acknowledge him as well as Constantine, as equal associates in the Imperial dignity.]
