Eustathios, the illustrious scholar and clergyman of the 12th century AD, wrote a commentary to Pindar’s epinician odes, from which only the proem survives. Eustathios treatment of the lyric poet, his ideas and criteria of literary criticism have not been re-assessed since Kambylis’ interpretation and text edition (1991). The aim of this paper is to supply this re-evaluation. Besides, a new Homeric allusion and some evidence for Eustathios’ productive imitation of Pindar’s style are dealt with.
