After study in Moscow, Berlin and Leeds, Boris Kayachev went on to held research fellowships in Trondheim, Dublin, Moscow, Oxford and Basel. Boris has published on a wide array of Greek and Latin poetry, but the main focus of his research has been on the Appendix Vergiliana. The present commentary on the Lydia follows on his earlier work on the Ciris (Allusion and Allegory: Studies in the Ciris, 2016; Ciris, a Poem from the Appendix Vergiliana, 2020), and will in turn be followed by a commentary on the Dirae.
