BE GRATEFUL AND GIVE THANKS FOR THE PRIEST

If a drought lasts for a long time and by now their seed in the ground and their trees are dying up, in such circumstances the priest of Zeus Lykaios prays at the water [of Hagno, a spring on the mountain] and makes all the sacrifices that custom requires; he then lowers an oak branch to the surface - not deep into the spring - and as the water is stirred water vapor rises from it, like mist, and after a short while the vapor becomes cloud and draws other clouds to it until it makes rain fall on the land of the Arcadians.
