Who Gallus Caesar was
The orphaned nephew whom Constantius II raised to Caesar in 351 and set over the East at Antioch — a professing Christian who translated the martyr Babylas's relics to Daphne to silence Apollo's oracle, and whose harsh rule ended with his summons west and beheading at Pola. His brother Julian drew from his fate a lifelong lesson in dissembling; the Babylas translation he ordered became Julian's most public humiliation a decade later.
Also listed in non-christian witnesses and roman emperors.
