Stephanos of Byzantium - Ethnika
Kanastron: a headland of Thrace and Macedonia. The ethnonym is 'Kanastraios'. Sophokles, in his commentary on the Argonautika, says 'Kanastraion', 'a promontory of Pallene'. But the ethnonyms are at odds, unless we should take this too in a similar way to 'Lechaion' and 'Lechaios', and 'Lykeion', the gymnasion, and 'Lykeios' Apollo, and 'Nymphaion' and 'Nymphaios'.
