of India. Six chapters of the eighth Book bring the reader through the country west of the Indus to the bank of that river, its passage, and the ensuing battle on the eastern bank, with the defeat of the army of Porus; whilst the ninth Book embraces Alexander's advance through the Punjab, his operations in descending the Jhelam and Chenab, his descent of the Indus, and exploration of its mouth, with an account also of the homeward march; and the least that can be said of Messrs. Heitland and Raven's editorial work, whether critical or explanatory, is, that no difficulty of text is overlooked or imperfectly handled, no discrepancy, as comparing Curtius with parallel authorities, ignored. A test-passage, wherein to prove this statement, may be taken in the fourteenth chapter of the eighth Book, the battle between Alexander and Porus, which is described with unflagging care and zeal from first to last, the situations and details being compared, and, where possible, reconciled with Arrian, the poetical phrases characteristic of Curtius pointed out and illustrated, and the unusual words, _e.g., copidas_ ("choppers" like a Goorka knife, the κοπὶς from the same root as κόπτω), clearly though succinctly explained. On Alexander's order to Cœnus in §§ 15 of the battle chapter, "ipse dextrum move et turbatis signa infer" (advance the right wing, &c.), an excellent note, for which Mr. Heitland undertakes the sole responsibility, accredits him, in our judgment, as a most sound historical commentator, by the exhaustiveness wherewith he reconciles Arrian and Curtius's view of Alexander's position and movements, and those of Cœnus. The former with the main body took the Indian horse in flank, before they could change their front, and enabled Cœnus to fall on what had been their front but was now their disordered flank: and as to the difficulty in the way of this explanation, that according to Arrian the war-chariots were in front of the Indian horse, it is justly deemed easier to conceive Cœnus eluding these clumsy adversaries, than Alexander expecting him to see from the Macedonian left the right moment for his own charge, and then wheel round the whole Indian army, and execute his orders opportunely. With the same lucidity is the whole narrative commented on: and every geographical, historical, or military difficulty investigated, with a commendable eye both to ancient and modern references and authorities. Equally interesting, too, will be found the elucidations of questions of style, such as in viii. §§ 10, where "igni _alita_ sepulchra" reveals a certainly post-Augustan but doubtfully Ciceronian form; or as in viii. 14 §§ 41 the use of "malum" (plague take you) borrowed interjectionally from the comic poets and, as is shown in the notes ad loc., from Cicero De Off. ii. §§ 53. Students, however, must search this volume minutely to understand aright the helps it affords to their just estimate of Quintus Curtius Rufus as a
