Marcus Sedatius Severianus

Marcus Sedatius Severianus (Latin: Marcus Sedatius C. f. Severianus Iulius Acer Metillius Nepos Rufinus Ti. Rutilianus Censor;Ancient Greek: Μ. Σηδάτιος Σεουηριανὸς; ca. 105-161/162) was a senator, consul, and Roman general during the 2nd-century AD, originally from Gaul. Sedatius was a provincial governor and later a provincial consul. His career led up to consul suffect in 153. However brilliant, his career did not progress quickly through the cursus honorum. He had to earn his way from patrician to the more prestigious senatorial order. It is distinguished through his link with the oracle of Glycon (Alexander of Abonoteichus) while it's end shows the military difficulties of the Empire during the reign of Marcus Aurelius. He was governor of Cappadocia at the start of the Roman war with Parthia during which he was convinced by the untrustworthy oracle to invade Armenia in 161, although Parthia had been making trouble in Armenia since the death of the emperor Antoninus Pius (died 7 March 161). Sedatius committed suicide while under siege in the Armenian city of Elegeia, on the upper Euphrates. He was replaced as governor of Cappadocia by Marcus Statius Priscus.

The origin of Severianus is fixed to the city of Lemonum (modern Poitiers) in the area inhabited by the Pictones, since the discovery from that city of an inscription concerning Severianus. Thus he's also found briefly mentioned by Lucian of Samosata who remembered his Gallic origins.
