Diogenes Laertius, Chrysippos 7.7.180
“Apollodorus the Athenian in his Summary of Beliefs, because he wants to demonstrate that the works of Epicurus were written with personal force and were prepared with far fewer quotations than the books of Chrysippos, says in this very wording: “if the books of [Chrysippos] were scrubbed of all the superfluous quotations, only empty paper would be left to him.”
So much for Apollodorus. The old women who used to sit next to [Chrysippos], according to Diocles, used to claim that he wrote 500 lines each day. Hekatôn reports that he turned to philosophy because the property left to him by his father was confiscated to the royal treasury.”
Καὶ Ἀπολλόδωρος δ᾿ ὁ Ἀθηναῖος ἐν τῇ Συναγωγῇ τῶν δογμάτων, βουλόμενος παριστάνειν ὅτι τὰ Ἐπικούρου οἰκείᾳ δυνάμει γεγραμμένα καὶ ἀπαράθετα ὄντα μυρίῳ πλείω ἐστὶ τῶν Χρυσίππου βιβλίων, φησὶν οὕτως αὐτῇ τῇ λέξει· “εἰ γάρ τις ἀφέλοι τῶν Χρυσίππου βιβλίων ὅσ᾿ ἀλλότρια παρατέθειται, κενὸς αὐτῷ ὁ χάρτης καταλελείψεται.” καὶ ταῦτα μὲν Ἀπολλόδωρος. ἡ δὲ παρεδρεύουσα πρεσβῦτις αὐτῷ, ὥς φησι Διοκλῆς, ἔλεγεν ὡς πεντακοσίους γράφοι στίχους ἡμερησίους. Ἑκάτων δέ φησιν ἐλθεῖν αὐτὸν ἐπὶ φιλοσοφίαν, τῆς οὐσίας αὐτοῦ τῆς πατρῴας εἰς τὸ βασιλικὸν ἀναληφθείσης.
