It appears, from the coins of Aphrodisias, in Caria, that there was a river Corsymus, or Corsynus, there.
In the article APHRODISIAS
the river is named Mosynus.
The name in the editions of Harduin and Sillig (Plin. Nat. 5.29
) is Orsinus. Harduin says that the editions of Pliny have Mossinus.
It seems likely that Corsynus or Corsymus is the true name, and that the other forms are corruptions.
