Passage 7.17.4
οὐ μὴν Ἕλλησί γε ἐξεγένετο ὄνασθαι τοῦ δώρου· Οὐεσπασιανοῦ γὰρ μετὰ Νέρωνα ἄρξαντος ἐς ἐμφύλιον στάσιν προήχθησαν, καὶ σφᾶς ὑποτελεῖς τε αὖθις ὁ Οὐεσπασιανὸς εἶναι φόρων καὶ ἀκούειν ἐκέλευσεν ἡγεμόνος, ἀπομεμαθηκέναι φήσας τὴν ἐλευθερίαν τὸ Ἑλληνικόν.
However, it was not granted to the Greeks to benefit from this gift. For after Nero, when Vespasian had become emperor, they fell once more into civil strife, and Vespasian ordered that they again become subjects, paying tribute and obeying a governor, declaring that the Greek people had forgotten how to use their freedom.
