Note 003
The Bosphorus has been very minutely described by Dionysius of Byzantium, who lived in the time of Domitian (Hudson, Geograph. Minor. tom. iii.), and by Gilles or Gyllius, a French traveller of the sixteenth century. Tournefort (Lettre XV.) seems to have used his own eyes, and the learning of Gyllius.
