What worried the crows in Callimachus' epigram?

This paper deals with the Callimachus' epigram devoted to Diodorus Cronus and attesting his great popularity as dialectician. New interpretation of the second croak of crows is proposed, according to which the crows worry about their future: "what will be with us further?". Thus both croaks of the crows are connected with the most important part of Diodorus' teaching, i. e. his theory of modality expressed in the so called "Master Argument".
