Gn. Metius, Q. Trajanus, a native of Pannonia, sent by the emperor Philip to appease a sedition in Moesia. Instead of obeying his master's command, he assumed the imperial purple, and soon after marched against him, and at his death became the only emperor. He signalized himself against the Persians; and, when he marched against the Goths, he pushed his horse into a deep marsh, from which he could not extricate himself, and he perished with all his army by the darts of the barbarians. A. D. 251, after a reign of two years.
