Who Isaac of Dalmatia was

The monk who, Sozomen relates, seized the bridle of the emperor Valens as he rode out to the Gothic war and foretold his ruin unless he restored the orthodox churches — Valens vowing to deal with him on his return, and burning to death at Adrianople instead. Isaac's cell grew into the first great monastery of the capital, the Dalmatou.

c. AD 445
[First attested ~60 years later.] As Valens marched out to the Gothic war, the monk Isaac cried to him: 'Give back, O emperor, the churches to the orthodox, and victory shall be given thee.' The emperor threatened to deal with him upon his return. 'If thou returnest,' said the monk, 'the Lord hath not spoken by me.' Valens did not return from Adrianople.
