The sagacity which every animal exhibits in its own behalf is wonderful, but in these it is remarkably so. The dragon has much difficulty in climbing up to so great a height, and therefore, watching the road, which bears marks of their footsteps when going to feed, it darts down upon them from a lofty tree. The elephant knows that it is quite unable to struggle against the folds of the serpent, and so seeks for trees or rocks against which to rub itself. The dragon is on its guard against this, and tries to prevent it, by first of all confining the legs of the elephant with the folds of its tail; while the elephant, on the other hand, endeavours to disengage itself with its trunk. The dragon, however, thrusts its head into its nostrils, and thus, at the same moment, stops the breath and wounds the most tender parts. When it is met unexpectedly, the dragon raises itself up, faces its opponent, and flies more especially at the eyes; this is the reason why elephants are so often found blind, and worn to a skeleton with hunger and misery. What other cause can one assign for such mighty strifes as these, except that Nature is desirous, as it were, to make an exhibition for herself, in pitting such opponents against each other? There is another story, too, told in relation to these combats—the blood of the elephant, it is said, is remarkably cold; for which reason, in the parching heats of summer,[1644] it is sought by the dragon with remarkable avidity. It lies, therefore, coiled up and concealed in the rivers, in wait for the elephants, when they come to drink; upon which it darts out, fastens itself around the trunk, and then fixes its teeth behind the ear, that being the only place which the elephant cannot protect with the trunk. The dragons, it is said, are of such vast size, that they can swallow the whole of the blood; consequently, the elephant, being thus drained of its blood, falls to the earth exhausted; while the dragon, intoxicated with the draught, is crushed beneath it, and so shares its fate. CHAP. 13. (13.)—DRAGONS. Æthiopia produces dragons, not so large as those of India, but still, twenty cubits in length.[1645] The only thing that surprises me is, how Juba came to believe that they have crests.[1646] The Æthiopians are known as the Asachæi, among whom they most abound; and we are told, that on those coasts four or five of them are found twisted and interlaced together like so many osiers in a hurdle, and thus setting sail, with their heads erect, they are borne along upon the waves, to find better sources of nourishment in Arabia.
