Note 254 — Chapter IV · ETHNOLOGY OF BRITAIN.
Reading edition
Bede mentions that the ‘Sinus Orientalis (Firth of Forth) habet in medio sui urbem Giudi.’ It is not impossible that this town may have taken its name from this Guidid or Giudid Gaethbrechach, and if it was on Inchkeith, the island may have taken its name from Gaeth. He must therefore have belonged to the British people of the Ottadeni, whose frontier city this was.
