Now the Araxes is said by some to be larger and by others to be smaller than the Ister: and they say that there are many islands in it about equal in size to Lesbos, and in them people dwelling who feed in the summer upon roots of all kinds which they dig up and certain fruits from trees, which have been discovered by them for food, they store up, it is said, in the season when they are ripe and feed upon them in the winter. Moreover it is said that other trees have been discovered by them which yield fruit of such a kind that when they have assembled together in companies in the same place and lighted a fire, they sit round in a circle and throw some of it into the fire, and they smell the fruit which is thrown on, as it burns, and are intoxicated by the scent as the Hellenes are with wine, and when more of the fruit is thrown on they become more intoxicated, until at last they rise up to dance and begin to sing.
