[1] Danube.
[2] Identified as an extract of the Chronicle of John of Antioch (fr. 237 Roberto = fr. 182 Mariev), who in turn drew on a Greek translation of Eutropius' Breviarium (9.15.1-2).
The extract concerns the decision of Aurelian (270-275) to abandon the three provinces of Dacia, which formed a large salient to the north of the Danube. Dacia had become increasingly isolated and untenable during the 260s owing to the large-scale inroads of the Goths and other Germanic peoples. At an uncertain date, Aurelian evacuated the civil and military administration, and at least part of the populace, south of the river to central Moesia, where he created a new province of Dacia Aureliana, with its capital at Serdica (modern Sofia), which lay between Moesia Superior and Moesia Inferior. The number and fate of the Romanised population remaining north of the Danube are disputed.
For Trajan see generally tau 902; for Aurelian, alpha 4458.
The toponym 'Mysia' correctly belonged to a region of north-western Asia Minor, but some Roman authors also applied this term to 'Moesia', the frontier provinces of the lower Danube. Cf. mu 1472.
