The 9th century Codex Sinaiticus gr. 491 transmits a series of homilies on Epiphany. In my paper I'd like to talk about three of them, CPG 4212 by Severian of Gabala, CPG 4882 attributed to Severian by Wenger in his editio princeps, and CPG 4456 by John Chrysostom. I'd like to focus on their transmission, their genre, their connection with the feast and last but not least their exegetical and theological approach.
