Венанций Фортунат
In 569, Justin and Sophia together reportedly sent a relic of the True Cross to Radegund. The event was commemorated in Vexilla Regis by Venantius Fortunatus. They also sent relics to Pope John III in an attempt to improve relations: the Cross of Justin II in the Vatican Museums, a crux gemmata, and a reliquary of the True Cross perhaps given at this point, has an inscription recording their donation and apparently their portraits on the ends of the arms on the reverse. This led to creation of poems by Venantius Fortunatus, which referred to Justin and Sophia as the new Constantine and the new Helena, and indicating Sophia's major role in the presentation of the relic.
