John Bostock translation
There are two chief passes over the chain of the Caucasus, both of which were known to the ancients. The first is between the eastern extremity of its chief north-eastern spur and the Caspian sea, near the modern Derbend. This was called “Albaniæ,” and sometimes, “Caspiæ Pylæ,” the “Albanian” or “Caspian Gates.” The other, which was nearly in the centre of the Caspian range, was called “Caucasiæ” or “Sarmaticæ Pylæ,” being the same as the modern pass of Dariyel, and probably the one here referred to.
