"Glycerius (fl. 470s) was Roman emperor of the West from 473 to 474. He served as comes domesticorum (commander of the palace guard) during the reign of Olybrius, until Olybrius died in November 472. After a four-month interregnum, Glycerius was proclaimed Western Emperor in March 473 by the magister militum (master of soldiers) and power behind the throne Gundobad. Very few of the events of his reign are known other than that during his reign an attempted invasion of Italy by the Visigoths was repelled, diverting them to Gaul. Glycerius also prevented an invasion by the Ostrogoths through gifts." - (en.wikipedia.org 11.08.2021)
