30'.

The exact site of the city of Rhages within this territory is somewhat doubtful.

All accounts place it near the eastern extremity; and as there are in this direction ruins of a town called Rhei or Rhey, it has been usual to assume that they positively fix the locality.

But similarity, or even identity, of name is an insufficient proof of a site; and, in the present instance, there are grounds for placing Rhages very much nearer to the Caspian Gates than the position of Rhei.

Arrian, whose accuracy is notorious, distinctly states that from the Gates to Rhages was only a single day's march, and that Alexander accomplished the distance in that time.
