Passage 1.21.1
εἰσὶ δὲ Ἀθηναίοις εἰκόνες ἐν τῷ θεάτρῳ καὶ τραγῳδίας καὶ κωμῳδίας ποιητῶν, αἱ πολλαὶ τῶν ἀφανεστέρων· ὅτι μὴ γὰρ Μένανδρος, οὐδεὶς ἦν ποιητὴς κωμῳδίας τῶν ἐς δόξαν ἡκόντων. τραγῳδίας δὲ κεῖνται τῶν φανερῶν Εὐριπίδης καὶ Σοφοκλῆς. λέγεται δὲ Σοφοκλέους τελευτήσαντος ἐσβαλεῖν ἐς τὴν Ἀττικὴν Λακεδαιμονίους, καὶ σφῶν τὸν ἡγούμενον ἰδεῖν ἐπιστάντα οἱ Διόνυσον κελεύειν τιμαῖς, ὅσαι καθεστήκασιν ἐπὶ τοῖς τεθνεῶσι, τὴν Σειρῆνα τὴν νέαν τιμᾶν· καί οἱ τὸ ὄναρ ἐς Σοφοκλέα καὶ τὴν Σοφοκλέους ποίησιν ἐφαίνετο ἔχειν, εἰώθασι δὲ καὶ νῦν ἔτι ποιημάτων καὶ λόγων τὸ ἐπαγωγὸν Σειρῆνι εἰκάζειν.
The Athenians have statues in their theatre of poets both of tragedy and comedy, most of whom are relatively obscure. For aside from Menander, there was no comic poet worthy of notable fame. Among the famous tragedians represented there are Euripides and Sophocles. They say that upon Sophocles' death the Lacedaemonians invaded Attica, and their commander had a vision of Dionysus standing over him and commanding him to honor with customary funeral rites the new Siren; and this dream seemed clearly to refer to Sophocles and his poetry, for even now it remains customary to liken the charm of poetry and eloquence to a Siren.
