§1.5.1Ὑποθησόμεθα δὲ ταύτης ἀρχὴν τῆς βύβλου τὴν πρώτην διάβασιν ἐξ Ἰταλίας Ῥωμαίων.
We shall set as the beginning of this book the first crossing of the Romans out of Italy.
αὕτη δʼ ἔστιν συνεχὴς μὲν τοῖς ἀφʼ ὧν Τίμαιος ἀπέλιπεν, πίπτει δὲ κατὰ τὴν ἐνάτην καὶ εἰκοστὴν πρὸς ταῖς ἑκατὸν ὀλυμπιάδα.
This is continuous with the events from where Timaeus left off, and it falls in the one hundred and twenty-ninth Olympiad.
§1.5.2διὸ καὶ ῥητέον ἂν εἴη πῶς καὶ πότε συστησάμενοι τὰ κατὰ τὴν Ἰταλίαν καὶ τίσιν ἀφορμαῖς μετὰ ταῦτα χρησάμενοι διαβαίνειν ὥρμησαν εἰς Σικελίαν· ταύτῃ γὰρ τῇ γῇ πρῶτον ἐπέβησαν τῶν ἐκτὸς τόπων τῆς Ἰταλίας.
Therefore, it must be told how and when they settled their affairs in Italy, and with what resources after this they set out to cross over into Sicily; for this was the first land outside Italy they set foot on.
§1.5.3καὶ ῥητέον αὐτὴν τὴν τῆς διαβάσεως αἰτίαν ψιλῶς, ἵνα μὴ τῆς αἰτίας αἰτίαν ἐπιζητούσης ἀνυπόστατος ἡ τῆς ὅλης ὑποθέσεως ἀρχὴ γένηται καὶ θεωρία.
And we must state the cause itself of the crossing simply, lest, with cause seeking cause, the starting point and study of our entire undertaking should become without foundation.
§1.5.4ληπτέον δὲ καὶ τοῖς καιροῖς ὁμολογουμένην καὶ γνωριζομένην ἀρχὴν παρʼ ἅπασι καὶ τοῖς πράγμασι δυναμένην αὐτὴν ἐξ αὑτῆς θεωρεῖσθαι, κἂν δέῃ τοῖς χρόνοις βραχὺ προσαναδραμόντας κεφαλαιώδη τῶν μεταξὺ πράξεων ποιήσασθαι τὴν ἀνάμνησιν.
And we must take a starting point that is agreed upon and recognized by all in terms of its dates, and capable of being examined by itself in terms of its events, even if we must run back a little in time to make a summary recollection of the transactions in the interval.
§1.5.5τῆς γὰρ ἀρχῆς ἀγνοουμένης ἢ καὶ νὴ Δίʼ ἀμφισβητουμένης οὐδὲ τῶν ἑξῆς οὐδὲν οἷόν τε παραδοχῆς ἀξιωθῆναι καὶ πίστεως· ὅταν δʼ ἡ περὶ ταύτης ὁμολογουμένη παρασκευασθῇ δόξα, τότʼ ἤδη καὶ πᾶς ὁ συνεχὴς λόγος ἀποδοχῆς τυγχάνει παρὰ τοῖς ἀκούουσιν.
For if the starting point is unknown, or indeed, by Zeus, disputed, none of the subsequent parts can be deemed worthy of acceptance and belief; but when an agreed opinion concerning this is established, then at once the entire continuous narrative also wins acceptance among the audience.
