A conversation with Przemysław Marciniak (University of Silesia) about books of fantasy, science fiction, horror, and alternative history that are either set in Byzantium or have a Byzantine ambiance. We talk about the features that signal a Byzantine setting and what the latter is good. Basically, we chat about books that we liked (or did not like). The conversation is based on Przemek's chapter 'Fantastic(al) Byzantium: The Image of Byzantium in Speculative Fiction,' in M. Kulhánková and P. Marciniak, eds., Byzantium in the Popular Imagination: The Modern Reception of the Byzantine Empire (I.B. Tauris 2023) 249-260.
