Tapuri or Tapyri (Ancient Greek: Τάπουροι or Τάπυροι or Τάπυρροι)[1][2] were a tribe in the Medes south of the Caspian Sea mentioned by Ptolemy and Arrian.[3] Ctesias refers to the land of Tapuri between the two lands of Cadusii and Hyrcania.[4]
^Of the lands which lie on the sea and of the others which border on these, Ninus subdued Egypt and Phoenicia, then Coele-Syria, Cilicia, Pamphylia, and Lycia, and also Caria, Phrygia, and Lydia; moreover, he brought under his sway the Troad, Phrygia on the Hellespont, Propontis, Bithynia, Cappadocia, and all the barbarian nations who inhabit the shores of the Pontus as far as the Tanais; he also made himself lord of the lands of the Cadusii, Tapyri, Hyrcanii, Drangi, of the Derbici, Carmanii, Choromnaei, and of the Borcanii, and Parthyaei; and he invaded both Persis and Susiana and Caspiana, as it is called, which is entered by exceedingly narrow passes, known for that reason as the Caspian Gates. 4 Many other lesser nations he also brought under his rule, about whom it would be a long task to speak. But since Bactriana was difficult to invade and contained multitudes of warlike men, after much toil and labour in vain he deferred to a later time the war against the Bactriani, and leading his forces back into Assyria selected a place excellently situated for the founding of a great city..
