The son of a humble schoolmaster, he displayed a marked inaptitude for literary pursuits; but, having entered the army, gradually rose to high military rank, land was indebted for much of his success in life to the singular faculty which he possessed of being able to drink to excess (bibit quantum hominum nemo

How the husband-spy discharged his task we are not told; but we find him at a subsequent period in the command of troops upon the Rhaetian frontier, and afterwards stationed on the Rhine. The Germans having succeeded in destroying certain Roman vessels in consequence of some carelessness or breach of duty on his part, in order to avoid immediate punishment, lie prevailed upon his soldiers to proclaim him emperor.
