Passage 1.25.8
Λαχάρην μὲν οὖν τούτων ἕνεκα κτείνουσιν ἄνδρες Κορωναῖοι· Δημήτριος δὲ ὁ Ἀντιγόνου τυράννων ἐλευθερώσας Ἀθηναίους τό τε παραυτίκα μετὰ τὴν Λαχάρους φυγὴν οὐκ ἀπέδωκέ σφισι τὸν Πειραιᾶ καὶ ὕστερον πολέμῳ κρατήσας ἐσήγαγεν ἐς αὐτὸ φρουρὰν τὸ ἄστυ, τὸ Μουσεῖον καλούμενον τειχίσας. ἔστι δὲ ἐντὸς τοῦ περιβόλου τοῦ ἀρχαίου τὸ Μουσεῖον ἀπαντικρὺ τῆς ἀκροπόλεως λόφος, ἔνθα Μουσαῖον ᾄδειν καὶ ἀποθανόντα γήρᾳ ταφῆναι λέγουσιν· ὕστερον δὲ καὶ μνῆμα αὐτόθι ἀνδρὶ ᾠκοδομήθη Σύρῳ. τότε δὲ Δημήτριος τειχίσας εἶχε·
For these reasons, Lachares was killed by men from Coronea. Demetrius, the son of Antigonus, after liberating the Athenians from tyranny, did not immediately restore to them the Piraeus following the flight of Lachares; later, after prevailing in war, he introduced a garrison into the city itself, fortifying the place called the Museum. Within the ancient enclosure, opposite the Acropolis, there is a hill called the Museum, where they say Musaeus used to sing and, when he died of old age, was buried. Later, a memorial was also erected there to a certain Syrian. At that time, Demetrius fortified it and held it.
