Passage 1.22.4
ἐς δὲ τὴν ἀκρόπολίν ἐστιν ἔσοδος μία· ἑτέραν δὲ οὐ παρέχεται, πᾶσα ἀπότομος οὖσα καὶ τεῖχος ἔχουσα ἐχυρόν. τὰ δὲ προπύλαια λίθου λευκοῦ τὴν ὀροφὴν ἔχει καὶ κόσμῳ καὶ μεγέθει τῶν λίθων μέχρι γε καὶ ἐμοῦ προεῖχε. τὰς μὲν οὖν εἰκόνας τῶν ἱππέων οὐκ ἔχω σαφῶς εἰπεῖν, εἴτε οἱ παῖδές εἰσιν οἱ Ξενοφῶντος εἴτε ἄλλως ἐς εὐπρέπειαν πεποιημέναι· τῶν δὲ προπυλαίων ἐν δεξιᾷ Νίκης ἐστὶν Ἀπτέρου ναός. ἐντεῦθεν ἡ θάλασσά ἐστι σύνοπτος, καὶ ταύτῃ ῥίψας Αἰγεὺς ἑαυτὸν ὡς λέγουσιν ἐτελεύτησεν.
There is only one way leading up into the acropolis; no other approach is possible, as it is steep on all sides and has a strong wall. The entrance gate (Propylaea) has a roof built of white stone, and down to my day surpassed all others both in the beauty and the size of its stones. As for the statues of horsemen, I cannot say exactly whether they are meant to represent the sons of Xenophon or were created simply as decorative figures. On the right-hand side of the Propylaea is the temple of Wingless Victory (Nike Apteros). From there the sea is clearly visible, and it is from that place, they say, that Aegeus threw himself down and died.
