Granddaughter of Theoderic  the Great; having been forced into marriage in 536 AD by Vitigis, she tried to betray Ravenna to the Byzantines in 538, supposedly in order to marry Belisarius (?) (Procop. Goth. 2,10,11). In 540 she and Vitigis (d. 542) were brought to Constantinople, and in 549/50 she married Germanus  (d. 550). Birth of a son, Germanus, in 550/1. M. bore the unusual title of a patricia (Iord. Get. 81).
