Note 2946 — BOOK IV. AN ACCOUNT OF COUNTRIES, NATIONS, SEAS, TOWNS, HAVENS, MOUNTAINS, RIVERS, DISTANCES, AND PEOPLES WHO NOW EXIST OR FORMERLY EXISTED.
John Bostock translation
Brotier thinks that under this name a part of Cornwall is meant, and that it was erroneously supposed to be an island. Parisot is of opinion that the copyists, or more probably Pliny himself, has made an error in transcribing Mictis for Vectis, the name of the Isle of Wight. It is not improbable however that the island of Mictis had only an imaginary existence.
