GRAVE COINS. Found at graves beneath the church’s bema wall, these coins date to the time of Emperor Valens (364–378) and Emperor Valentinian (378–383). The Valens coin (upper) depicts Valens on its front; its reverse shows the emperor holding a labarum (imperial standard) while dragging a captive. The lower coin depicts Valentinian II on one side and the goddess Roma seated with a globe and spear on the other.
