The first of these passages suggests that Theodosius pursued the Scots across the sea, or at least made a naval demonstration in the Irish Channel, and this is perhaps supported by the passage in Pacatus, Panegyric, c. 5: attritam pedestribus praeliis Britanniam referam? Saxo consumptus bellis naualibus offeretur. redactum ad paludes suas Scotum loquar?
(2) Troubles brought on Britain through the revolt of Maximus, and pacification by Stilicho. Zosimus (source: doubtless Eunapius), 4, 35: the soldiers, having crowned Maximus, παραχρῆμα τὸν Ὠκεανὸν ναυσὶ διαβάντες landed at the mouth of the Rhine. Cp. Orosius 7, 34, 9. (While Zosimus imputes the blame of the insurrection to Maximus, Orosius says that he was created Emperor inuitus propemodum.) The rebellion was brought to an end by the death of Maximus in A.D. 388 (Idatius and Prosper Tiro, ad ann.), so that it cannot have been before that year that the Britannic legions returned to Britain.
Now the only contemporary evidence as to the fortunes of Britain during the fifteen years which followed the revolt of Maximus consists of two passages of Claudian: (1) In Eutropium, i. 393 (composed A.D. 399, June to Sept.)—
fracto secura Britannia Picto,
where the context implies that this was accomplished during the reign of Honorius (te principe, 391); (2) De Consulatu Stilichonis, ii. 247 sqq. (composed end of A.D. 399):—
Inde Caledonio uelata Britannia monstro,
Ferro picta genas, cuius uestigia uerrit
Caerulus Oceanique aestum mentitur amictus:
“Me quoque uicinis pereuntem gentibus” inquit
“Muniuit Stilicho, totam cum Scottus Hiuernen
