[4,68] Τῷ ἀνδρὶ τούτῳ πατὴρ μὲν ἦν Μάρκος Ἰούνιος ἑνὸς τῶν σὺν Αἰνείᾳ τὴν ἀποικίαν στειλάντων ἀπόγονος, ἐν τοῖς ἐπιφανεστάτοις Ῥωμαίων ἀριθμούμενος δι´ ἀρετήν, μήτηρ δὲ Ταρκυνία τοῦ προτέρου βασιλέως Ταρκυνίου θυγάτηρ· αὐτὸς δὲ τροφῆς τε καὶ παιδείας τῆς ἐπιχωρίου πάσης μετέλαβε καὶ φύσιν εἶχε πρὸς οὐδὲν τῶν καλῶν ἀντιπράττουσαν. ἐπεὶ δὲ Τύλλιον ἀποκτείνας Ταρκύνιος σὺν ἄλλοις ἀνδράσι πολλοῖς καὶ ἀγαθοῖς καὶ τὸν ἐκείνου πατέρα διεχρήσατο ἀφανεῖ θανάτῳ δι´ οὐδὲν μὲν ἀδίκημα, τοῦ δὲ πλούτου προαχθεὶς εἰς ἐπιθυμίαν, ὃν ἐκ παλαιᾶς τε καὶ προγονικῆς παραλαβὼν εὐτυχίας ἐκέκτητο, καὶ σὺν αὐτῷ τὸν πρεσβύτερον υἱὸν εὐγενές τι φρόνημα διαφαίνοντα καὶ τὸ μὴ τιμωρῆσαι τῷ θανάτῳ τοῦ πατρὸς οὐκ ἂν ὑπομείναντα, νέος ὢν ὁ Βροῦτος ἔτι καὶ κομιδῇ βοηθείας συγγενικῆς ἔρημος ἔργον ἐπεχείρησε ποιῆσαι πάντων φρονιμώτατον, ἐπίθετον ἑαυτοῦ καταψεύσασθαι μωρίαν· καὶ διέμεινεν ἅπαντα τὸν ἐξ ἐκείνου χρόνον, ἕως {οὗ} τὸν ἐπιτήδειον ἔδοξε καιρὸν ἔχειν, φυλάττων τὸ προσποίημα τῆς ἀνοίας, ἐξ οὗ ταύτης ἔτυχε τῆς ἐπωνυμίας· τοῦτ´ αὐτὸν ἐρρύσατο μηδὲν δεινὸν ὑπὸ τοῦ τυράννου παθεῖν πολλῶν καὶ ἀγαθῶν ἀνδρῶν ἀπολλυμένων.

[4,68] The father of Brutus was Marcus Junius, a descendant of one of the colonists in the company of Aeneas, and a man who for his merits was ranked among the most illustrious of the Romans; his mother was Tarquinia, a daughter of the first King Tarquinius. He himself enjoyed the best upbringing and education that his country afforded and he had a nature not averse to any noble accomplishment. Tarquinius, after he had caused Tullius to be slain, put Junius' father to death secretly, together with many other worthy men, not for any crime, but (p483) because he was in possession of the inheritance of an ancient family enriched by the good fortune of his ancestors, the spoils of which Tarquinius coveted; and together with the father he slew the elder son, who showed indications of a noble spirit unlikely to permit the death of his father to go unavenged. Thereupon Brutus, being still a youth and entirely destitute of all assistance from his family, undertook to follow the most prudent of all courses, which was to feign a stupidity which was not his; and he continued from that time to maintain this pretence of folly from which he acquired his surname, till he thought the proper time had come to throw it off. This saved him from suffering any harm at the hands of the tyrant at a time when many good men were perishing.
