Plato, Laws 924e

δʼ εἶναι τῇ θυγατρί, τοῦτο δὲ παραλείπῃ διὰ τὴν ἀδύνατον σκέψιν. νόμος τοίνυν εἰς δύναμιν ὅδε περὶ τῶν τοιούτων κείσθω· ἐὰν ὁ μὴ διαθέμενος θυγατέρας λείπῃ, τοῦδε ἀποθανόντος, ἀδελφὸς ὁμοπάτωρ ἢ ἄκληρος ὁμομήτριος ἐχέτω τὴν θυγατέρα καὶ τὸν κλῆρον τοῦ τελευτήσαντος· ἐὰν δὲ μὴ ᾖ ἀδελφός, ἀδελφοῦ δὲ παῖς, ὡσαύτως, ἐὰν ἐν ἡλικίᾳ πρὸς ἀλλήλους ὦσιν· ἐὰν δὲ μηδὲ εἷς τούτων, ἀδελφῆς δὲ παῖς ᾖ, κατὰ ταὐτά· τέταρτος δὲ πατρὸς ἀδελφός, πέμπτος δὲ τούτου παῖς, ἕκτος δὲ ἀδελφῆς πατρὸς ἔκγονος. ὡσαύτως δὲ τὸ γένος ἀεὶ πορευέσθω κατʼ ἀγχιστείαν, ἐάν τις παῖδας θηλείας καταλείπῃ,

Accordingly, the law that we shall enact, as the best in our power touching such matters, will be this:—If a man dies intestate and leaves daughters, that brother who is born of the same father or of the same mother and who is without a lot shall take the daughter and the lot of the deceased; failing a brother, if there be a brother’s son, the procedure shall be the same, provided that the parties be of an age suited the one to the other; failing one of these, the same rule shall hold for a sister’s son; then, fourthly, for a father’s brother; and, fifthly, for his son; and, sixthly, for the son of a father’s sister.
