XI. Besides the large works, we learn from Photius (cod. 93) that Arrian wrote the biographies of the Corinthian Timoleon and of the Syracusan Dion. Lucian (Alex. 2), also states that he wrote the life of Tilliborus, the notorious robber of Asia Minor. XII. A valuable geographical work by Arrian has come down to us, called “Περίπλους πόντου Εὐξείνου”, a description of a voyage round the coasts of the Euxine. This naval expedition was executed by him as Governor of Cappadocia. The Alani, or, Albani of the East, a tribe related to the Massagetae, were threatening to invade his province, and he made this voyage with a view of fortifying the most important strategic points on the coast. From section 26 of the Periplus we find that this voyage must have taken place about the year 131 or 132 A.D.; for the death of King Cotys II., noticed in that passage as just dead, is proved by Böckh’s investigations to have occurred in 131 A.D. Two other geographical works, _The Periplus of the Red Sea_ and _The Periplus of the Euxine_, formerly ascribed to Arrian, are proved to belong to a later date. XIII. A work on _Tactics_, composed 137 A.D. In many parts this book agrees nearly verbally with the larger work of Aelian on the same subject; but Leo Tacticus (vii. 85) expressly mentions the two works as distinct. XIV. _An Array of Battle against the Alani_, is a fragment discovered in the seventeenth century in the Description of his Battles with the Alani, who invaded his province, probably 137 A.D., as Arrian had previously feared.[10] XV. A small work by Arrian on the Chase, forms a supplement to Xenophon’s book on the same subject. It is entitled _Cynegeticus of Arrian or the second Xenophon the Athenian_. The best editions of the Anabasis are the following:—The _editio princeps_ by Trincavelli, Venice, 1535; Gerbel, Strassburg, 1539; Henri Estienne, 1575; N. Blancardus, Amsterdam, 1668; J.
