Note {2} — Chapter XXV
Henry Yule translation
Note 2.—Respecting the Iron Gates, see vol. i. p. 53. The Caspian is here called the Sea of Sarain, probably for Sarai, after the great city on the Volga. For we find it in the Catalan Map of 1375 termed the Sea of Sarra. Otherwise Sarain might have been taken for some corruption of Shirwán. (See vol. i. p. 59, note 8.)
