In the vast army of Tigranes, which was vanquished by Lucullus, seventeen thousand horse only were completely armed. Antiochus brought fifty-four elephants into the field against the Romans: by his frequent wars and negotiations with the princes of India, he had once collected a hundred and fifty of those great animals; but it may be questioned whether the most powerful monarch of Hindostan evci formed a line of battle of seven hundred elephants. Instead of three or four thousand elephants, which the Great Mogul was supposed to possess, Tavernier (Voyages, part ii. l. i. p. 198) discovered, by a more accurate inquiry, that he had only five hundred for his baggage, and eighty or ninety for the service of war. The Greeks have varied with regard to the number which Porus brought into the field; but Quintus Curtius, (viii. 13,) in this instance judicious and moderate, is contented with eighty-five elephants, distinguished by their size and strength. In Siam, where these animals are the most numerous and the most esteemed, eighteen elephants are allowed as a sufficient proportion for each of the nine brigades into which a just army is divided. The whole number, of one hundred and sixty-two elephants of war, may sometimes be doubled. Hist. des Voyages, tom. ix. p. 260. * Note: Compare Gibbon’s note 10 to ch. lvii—M.] 50 (return) [ Hist.
