Note 92 — Chapter II · THE ROMAN PROVINCE IN SCOTLAND.
Reading edition
Illud tamen sufficiet dici, quod eo tempore Picti in duas gentes divisi, Dicalidonas et Vecturiones, itidemque Attacotti, bellicosa hominum natio, et Scotti, per diversa vagantes, multa populabantur.—Ammian. Mar. xxvii. 8, 9.
The ‘Caledonii’ of Dio we know were the most northerly of the two nations; and the ‘Dicalidonæ’ of Ammianus must have extended along the coast bounded by the Deucaledonian Sea of Ptolemy.
