lemmatizing: ἔσπετε νῦν μοι Μοῦσαι Ὀλύμπια δώματ' ἔχουσαι
It has already been noted in the comment on I.02.484 that the Master Narrator tends to re-invoke the Muse or the Muses at special moments of poetic self-awareness about the need for high fidelity to tradition (see also Martin 1989:238). Such a moment is now at hand as Agamemnon the over-king is about to have his own moment of experiencing an ‘epic high point’. At such a moment, the Narrator must be ready to do his very best in recapturing that heroic experience. And, to express his readiness, the Narrator in all his self-awareness will now re-invoke the Muse or the Muses. In this context, the ‘I’ who is re-invoking the Muse(s) is meant to be seen as a re-enactment of ‘Homer’ himself, as originally enacted by the speaker who invokes the Muse at I.01.001 and at O.01.001.
