Matasuntha

Matasuentha or Matasuntha (fl. 550) was a daughter of Eutharic and Amalasuntha. She was a sister of Athalaric, King of the Ostrogoths. Their maternal grandparents were Theodoric the Great and Audofleda.

According to the Getica by Jordanes,

"Eutharic, who married Amalasuentha...begat Athalaric and Mathesuentha. Athalaric died in the years of his childhood, and Mathesuentha married Vitiges, to whom she bore no child. Both of them were taken together by Belisarius to Constantinople. When Vitiges passed from human affairs, Germanus the patrician, a cousin of the Emperor Justinian, took Mathesuentha in marriage and made her a Patrician Ordinary. And of her he begat a son, also called Germanus. But upon the death of Germanus, she determined to remain a widow."

Her son Germanus was born following the death of his father (late 550/early 551). Nothing further is known of him with certainty, although he can possibly be identified with the patricius Germanus, a leading senator in the reign of Emperor Maurice (r. 582–602), whose daughter married Maurice's eldest son Theodosius. Michael Whitby identifies the younger Germanus with Germanus, a son-in-law of Tiberius II Constantine and Ino Anastasia.
