or to serve as a legitimate ground for retreat, to one who prided himself on a full measure of Spartan courage. [257] Xenoph. Hellen. i, 6, 32; Diodor. xiii, 97, 98; the latter reports terrific omens beforehand for the generals. The answer has been a memorable one, more than once adverted to, Plutarch, Laconic. Apophthegm. p. 832; Cicero, De Offic. i, 24. The Athenian fleet was so marshalled, that its great strength was placed in the two wings; in each of which there were sixty Athenian ships, divided into four equal divisions, each division commanded by a general. Of the four squadrons of fifteen ships each, two were placed in front, two to support them in the rear. Aristokratês and Diomedon commanded the two front squadrons of the left division, Periklês and Erasinidês the two squadrons in the rear: on the right division, Protomachus and Thrasyllus commanded the two in front, Lysias and Aristogenês the two in the rear. The centre, wherein were the Samians and other allies, was left weak, and all in single line: it appears to have been exactly in front of one of the isles of Arginusæ, while the two other divisions were to the right and left of that isle. We read with some surprise that the whole Lacedæmonian fleet was arranged by single ships, because it sailed better and manœuvred better than the Athenians; who formed their right and left divisions in deep order, for the express purpose of hindering the enemy from performing the nautical manœuvres of the diekplus and the periplus.[258] It would seem that the Athenian centre, having the land immediately in its rear, was supposed to be better protected against an enemy “sailing through the line out to the rear, and sailing round about,” than the other divisions, which were in the open waters; for which reason it was left weak, with the ships in single line. But the fact which strikes us the most is, that, if we turn back to the beginning of the war, we shall find that this diekplus and periplus were the special manœuvres of the Athenian navy, and continued to be so even down to the siege of Syracuse; the Lacedæmonians being at first absolutely unable to perform them at all, and continuing for a long time to perform them far less skilfully than the Athenians. Now, the comparative value of both parties is reversed: the superiority of nautical skill has passed to the Peloponnesians and their allies: the precautions whereby that superiority is neutralized or evaded, are forced as a necessity on the Athenians. How astonished would the Athenian admiral Phormion have been, if he could have witnessed the fleets and the order of battle at Arginusæ! [258] Xenoph. Hellen. i, 6, 31. Οὕτω δ᾽ ἐτάχθησαν (οἱ Ἀθηναῖοι) ἵνα μὴ διέκπλουν διδοῖεν· χεῖρον γὰρ ἔπλεον. Αἱ δὲ τῶν Λακεδαιμονίων ἀντιτεταγμέναι ἦσαν ἅπασαι ἐπὶ μιᾶς, ὡς πρὸς διέκπλουν καὶ περίπλουν παρεσκευασμέναι, διὰ τὸ βέλτιον πλεῖν. Contrast this with Thucyd. ii, 84-89 (the speech of Phormion), iv, 12; vii, 36.
