Antioch (Antalaya), Syria — 353
Amazing luminous cross
As Constantius the Victorious, proclaimed Gallus as Caesar, he saw a cross in the form of a column of light appear in the western sky over Antioch. “After these things, the Emperor Constantius having created Gallus his kinsman Caesar, and given him his own name, sent him to Antioch in Syria, providing thus for the guarding of the eastern parts. When Gallus was entering this city, the Savior’s sign appeared in the East: for a pillar in the form of a cross seen in the heavens gave occasion of great amazement to the spectators.” (Ecc. Hist. 2.28.2)
