Histories

It is for this sand that the Indians set forth into the desert. They harness three camels apiece, males on either side sharing the drawing, and a female in the middle: the man himself rides on the female, that when harnessed has been taken away from as young an offspring as may be. Their camels are as swift as horses, and much better able to bear burdens besides.

I do not describe the camel's appearance to Greeks, for they know it; but I shall tell them something that they do not know concerning it: the hindlegs of the camel have four thighbones and four knee-joints; its genitals are turned towards the tail between the hindlegs.
