mvp-comment-138-1 255 αὐτῷ διαχαράσσεται is rendered by Hunt 'expresses himself therewith.' But that is hard to justify, and I should prefer to suppose that there is an allusion to the sound of the πλῆκτρον as it scrapes across the strings of the lyre. Cf. Plut. de soll. an. 20 p. 974 Β ὁ δὲ δράκων τῷ μαράθρῳ τὸν ὀφθαλμὸν ἀμβλυώττοντα λεπτύνων καὶ διαχαράττων. We might render: 'who in the world is setting our teeth on edge with it?' Compare the contemptuous use of catgut-scraper and the like in English; for the humour of the situation was enhanced by the satyrs' lack of musical appreciation. Wilamowitz seems to recognize this by the reference to 'Silen, dem sie (Musik) durch Mark und Bein geht' (p. 4511), but refuses to admit that the παρεπιγραφή ( ῥοῖβδος 107) can be used for the sound of the lyre. Rossbach's conjecture αὐτὸ διαχαρίζεται is mistaken.
