§3.21.1τὸ δὲ τεῖχος ἦν τῶν Πελοποννησίων τοιόνδε τῇ οἰκοδομήσει.
The wall of the Peloponnesians was of the following construction.
εἶχε μὲν δύο τοὺς περιβόλους, πρός τε Πλαταιῶν καὶ εἴ τις ἔξωθεν ἀπ’ Ἀθηνῶν ἐπίοι, διεῖχον δὲ οἱ περίβολοι ἑκκαίδεκα πόδας μάλιστα ἀπ’ ἀλλήλων.
It had two lines of fortifications, one facing Plataea and the other facing outwards in case anyone should attack from Athens; and these fortifications were about sixteen feet apart from each other.
§3.21.2τὸ οὖν μεταξὺ τοῦτο [οἱ ἑκκαίδεκα πόδες ] τοῖς φύλαξιν οἰκήματα διανενεμημένα ᾠκοδόμητο, καὶ ἦν ξυνεχῆ ὥστε ἓν φαίνεσθαι τεῖχος παχὺ ἐπάλξεις ἔχον ἀμφοτέρωθεν.
Therefore, this intervening space [the sixteen feet] had been built as quarters partitioned out for the guards, and these were continuous, so that it appeared to be a single thick wall, having battlements on both sides.
§3.21.3διὰ δέκα δὲ ἐπάλξεων πύργοι ἦσαν μεγάλοι καὶ ἰσοπλατεῖς τῷ τείχει, διήκοντες ἔς τε τὸ ἔσω μέτωπον αὐτοῦ καὶ οἱ αὐτοὶ καὶ τὸ ἔξω, ὥστε πάροδον μὴ εἶναι παρὰ πύργον, ἀλλὰ δι’ αὐτῶν μέσων διῇσαν.
At intervals of ten battlements there were large towers, of equal width with the wall, extending to both its inner face and, the very same towers, to its outer face, so that there was no passage along the side of a tower, but they had to go through the middle of them.
§3.21.4τὰς οὖν νύκτας, ὁπότε χειμὼν εἴη νοτερός, τὰς μὲν ἐπάλξεις ἀπέλειπον, ἐκ δὲ τῶν πύργων ὄντων δι’ ὀλίγου καὶ ἄνωθεν στεγανῶν τὴν φυλακὴν ἐποιοῦντο.
Therefore, at night, whenever there was stormy and wet weather, they would leave the battlements, and keep watch from the towers, which were at short intervals and roofed over at the top.
τὸ μὲν οὖν τεῖχος ᾧ περιεφρουροῦντο οἱ Πλαταιῆς τοιοῦτον ἦν.
Such, then, was the wall by which the Plataeans were blockaded.
