Note 90 — Chapter LXXVI · FROM THE PEACE OF ANTALKIDAS DOWN TO THE SUBJUGATION OF OLYNTHUS BY SPARTA.

In 1627, during the Thirty years’ War, the German town of Wolfenbüttel was constrained to surrender in the same manner, by damming up the river Ocker which flowed through it; a contrivance of General Count Pappenheim, the Austrian besieging commander. See Colonel Mitchell’s Life of Wallenstein, p. 107.

The description given by Xenophon of Mantinea as it stood in 385 B.C., with the river Ophis, a considerable stream, passing through the middle of it, is perfectly clear. When the city, after having been now broken up, was rebuilt in 370 B.C., the site was so far changed that the river no longer ran through it. But the present course of the river Ophis, as given by excellent modern topographical examiners, Colonel Leake and Kiepert, is at a very considerable distance from the Mantinea rebuilt in 370 B.C.; the situation of which is accurately known, since the circuit of its walls still remains distinctly marked. The Mantinea of 370 B.C., therefore, as compared with the Mantinea in 385 B.C., must have been removed to a considerable distance—or else the river Ophis must have altered its course. Colonel Leake supposes that the Ophis had been artificially diverted from its course, in order that it might be brought through the town of Mantinea; a supposition, which he founds on the words of Xenophon,—σοφωτέρων γενομένων ταύτῃ γε τῶν ἀνθρώπων, τὸ μὴ διὰ τειχῶν ποταμὸν ποιεῖσθαι (Hellen. v, 2, 7). But it is very difficult to agree with him on this point, when we look at his own map (annexed to the Peloponnesiaca) of the Mantinice and Tegeatis, and observe the great distance between the river Ophis and Mantinea; nor do the words of Xenophon seem necessarily to imply any artificial diversion of the river. It appears easier to believe that the river has changed its course. See Leake, Travels in Morea, vol. iii, ch. xxiv, p. 71; and Peloponnesiaca, p. 380; and Ernst Curtius, Peloponnesos, p. 239—who still, however, leaves the point obscure.
