The Roman History · Amm. 20.1.1

These were the events which took place in Illyricum and in the East. But the next year, that of Constantius's tenth and Julian's third consulship, the affairs of Britain became troubled, in consequence of the incursions of the savage nations of Picts and Scots, who breaking the peace to which they had agreed, were plundering the districts on their borders, and keeping in constant alarm the provinces exhausted by former disasters, Cæsar, who was wintering at Paris, having his mind divided by various cares, feared to go to the aid of his subjects across the channel (as we have related Constans to have done), lest he should leave the Gauls without a governor, while the Allemanni were still full of fierce and warlike inclinations.
