Сократ Схоластик
Eudoxia and Valentinian III married on 29 October 437, in Thessalonike, their marriage marking the reunion of the two halves of the House of Theodosius. The marriage was recorded by Socrates of Constantinople, the Chronicon Paschale and Marcellinus Comes. In 439, Eudoxia was granted the title of "Augusta", with the birth of their first daughter Eudocia. They also had a second daughter, Placidia. The births and eventual fates of the two daughters were recorded by Priscus, Procopius, John Malalas and the Chronicon Paschale.
