[350] κεφαλῆφιν here seems to be a locative, and to shew that the common gen. after verbs of aiming is also to be regarded as local. χαλκόφι in the next line is clearly used as an ablative; but it is a question if this use does not also go back to a locative sense; compare Arkadian “ἐξ” and “ἀπό” with dat. The forms in “-φι”(“ν”) may then all be reduced to either a local or an instrumental sense, with the exception of a few false archaisms (see H. G. §§ 154-8).
