John of Ephesus
In September 578, Justin II appointed Tiberius as his co-emperor, and on 5 October 578, Justin died and Tiberius became sole emperor. According to John of Ephesus, Sophia sent Patriarch Eutychius of Constantinople to Tiberius to convince him to divorce Ino, offering both herself and her adult daughter Arabia as prospective brides for the new Emperor. Tiberius refused.
