Reading edition
Like many other geographical names of ancient and modern times, this was used in both a wider and a narrower sense. It is applied by Herodotus in some passages to the whole region from the Pontus to the Hellespont; in others to the immediate neighbourhood of the Hellespont. It is used here in the wider sense.
