The application of the name Tanais to the Syr seems to indicate a real confusion with Colchian Caucasus.
Muller, it had its origin in the worship of Zeus Laphystius; the fleece is the pledge of reconciliation; Jason is a propitiating god of health, Medea a goddess akin to Hera; Aeetes is connected with the Colchian sun-worship. Forchhammer saw in it an old nature symbolism; Jason, the god of healing and fruitfulness, brought the fleece - the fertilizing rain-cloud - to the western land that was parched by the heat of the sun.
