Note 39 — Chapter II · THE SEVEN PROVINCES OF SCOTLAND.
Reading edition
Bede tells us (B. i. c. 12) that the Picts and Scots were termed transmarine nations, not because they came from beyond Britain, but because they belonged to that remote part of Britain beyond the two firths. The word Transmarine Scotland is adopted as a convenient term for Scotland beyond the Firths of Forth and Clyde.
