male-palms, and tie them upon the date-bearing palms, so that their gall-fly may enter into the date and ripen it and that the fruit of the palm may not fall off: for the male-palm produces gall-flies in its fruit just as the wild-fig does. 194. But the greatest marvel of all the things in the land after the city itself, to my mind is this which I am about to tell: Their boats, those I mean which go down the river to Babylon, are round and all of leather: for they make ribs for them of willow which they cut in the land of the Armenians who dwell above the Assyrians, and round these they stretch hides which serve as a covering outside by way of hull, not making broad the stern nor gathering in the prow to a point, but making the boats round like a shield: and after that they stow the whole boat with straw and suffer it to be carried down the stream full of cargo; and for the most part these boats bring down casks of palm-wood 200 filled with wine. The boat is kept straight by two steering-oars and two men standing upright, and the man inside pulls his oar while the man outside pushes. 201 These vessels are made both of very large size and also smaller, the largest of them having a burden of as much as five thousand talents' weight; 202 and in each one there is a live ass, and in those of larger size several. So when they have arrived at Babylon in their voyage and have disposed of their cargo, they sell by auction the ribs of the boat and all the straw, but they pack the hides upon their asses and drive them off to Armenia: for up the stream of the river it is not possible by any means to sail, owing to the swiftness of the current; and for this reason they make their boats not of timber but of hides. Then when they have come back to the land of the Armenians, driving their asses with them, they make other boats in the same manner. 195. Such are their boats; and the following is the manner of dress which they use, namely a linen tunic reaching to the feet, and over this they put on another of wool, and then a white mantle thrown round, while they have shoes of a native fashion rather like the Boeotian slippers. They wear their hair long and bind their heads round with fillets, 203 and they are anointed over the whole of their body with perfumes. Each man has a seal and a staff carved by hand, and on each staff is carved either an apple or a rose or a lily or an eagle or some other device, for it is not their custom to have a staff without a device upon it.
