External witness
Who Constantius I Chlorus was
The tetrarch of Gaul and Britain who executed the persecution edicts at their minimum — razing buildings, Lactantius says, but sparing every life — and whose death at York in 306 put the army's purple on his son Constantine. Eusebius made him the persecution's standing counter-example: the one persecutor's colleague whose house God prospered. Distinct from his grandson Constantius II.
