Reading edition
Dioscor. iii. 2. It has been conjectured by Prosper Alpinus that the Rha was brought to Pontos from the banks of the Volga, as Ammianus Marcellinus in fact, relates: Rha vicinus est amnis, in cujus superciliis quædam vegetabilis ejusdem nominis gignitur radix, proficiens ad usus multiplices medelarum, l. xxii. c. 8, p. 340.
