§7.189.1λέγεται δὲ λόγος ὡς Ἀθηναῖοι τὸν Βορέην ἐκ θεοπροπίου ἐπεκαλέσαντο, ἐλθόντος σφι ἄλλου χρηστηρίου τὸν γαμβρὸν ἐπίκουρον καλέσασθαι. Βορέης δὲ κατὰ τὸν Ἑλλήνων λόγον ἔχει γυναῖκα Ἀττικήν, Ὠρειθυίην τὴν Ἐρεχθέος.
A story is told that the Athenians, in consequence of an oracle, called upon Boreas to help them, another oracle having come to them to "call upon their son-in-law as an ally." Now Boreas, according to the account of the Greeks, has an Attic wife, Orithyia, the daughter of Erechtheus.
§7.189.2κατὰ δὴ τὸ κῆδος τοῦτο οἱ Ἀθηναῖοι, ὡς φάτις ὅρμηται, συμβαλλόμενοι σφίσι τὸν Βορέην γαμβρὸν εἶναι, ναυλοχέοντες τῆς Εὐβοίης ἐν Χαλκίδι ὡς ἔμαθον αὐξόμενον τὸν χειμῶνα ἢ καὶ πρὸ τούτου, ἐθύοντό τε καὶ ἐπεκαλέοντο τόν τε Βορέην καὶ τὴν Ὠρειθυίην τιμωρῆσαι σφίσι καὶ διαφθεῖραι τῶν βαρβάρων τὰς νέας, ὡς καὶ πρότερον περὶ Ἄθων.
It was indeed by virtue of this kinship that the Athenians, as the rumor went, concluding that Boreas was their son-in-law, while they were lying in wait with their ships at Chalcis in Euboea, as soon as they perceived that the storm was rising, or even before this, offered sacrifices and called upon both Boreas and Orithyia to help them and to destroy the ships of the barbarians, just as had happened before around Athos.
§7.189.3εἰ μέν νυν διὰ ταῦτα τοῖσι βαρβάροισι ὁρμέουσι Βορέης ἐπέπεσε, οὐκ ἔχω εἰπεῖν· οἱ δʼ ὦν Ἀθηναῖοι σφίσι λέγουσι βοηθήσαντα τὸν Βορέην πρότερον καὶ τότε ἐκεῖνα κατεργάσασθαι, καὶ ἱρὸν ἀπελθόντες Βορέω ἱδρύσαντο παρὰ ποταμὸν Ἰλισσόν.
Now, whether it was for this reason that Boreas fell upon the barbarians as they lay at anchor, I cannot say; but the Athenians, at any rate, say that Boreas had helped them before and then also accomplished those things, and when they returned, they founded a sanctuary of Boreas by the river Ilissus.
