hereditary customs: Ar. and P. τὰ πάτρια.

Alas! How bad the custom that prevails in Greece: οἴμοι καθ' Ἑλλάδ' ὡς κακῶς νομίζεται (Euripides, Andromache 693).
we will say it is not the custom in Greece to bury on land such as die at sea: V. ἀλλ' οὐ νομίζειν φήσομεν καθ' Ἑλλάδα χέρσῳ καλύπτειν τοὺς θανόντας ἐναλίους (Euripides, Helen 1065).
it is a custom: P. and V. νομίζεται.
