Hellespontus
(
Ἑλλήσποντος).
1.
Now the Dardanelles, the long narrow strait which joins the Propontis (Sea of Marmora) with
the Aegean Sea. Its length is some fifty miles, and its width varies from six at the upper
end to one or less. The narrowest part is between the ancient cities of Sestus and
Abydus, where Leander is said to have swum across to visit Hero. (See
Leander.) Here, also,
Xerxes
(q.v.) crossed on his bridge of boats. The name
Ἑλλήσποντος (Sea of Hellé) was derived from the myth of
Hellé; on which see the article
Phrixus.

Under the Roman Empire, the name Hellespontus was given to a province in the northern part
of Mysia, with Cyzicus for its capital.
