There’s a new translation of Cyril of Alexandria’s Festal Letters 1-12, by Philip R. Amidon, S.J., in The Fathers of the Church series (Vol. 118). See here. This look at his pastoral side will be interesting.
There is also a proposed re-translation of Cyril’s majesterial commentary on John–it runs some 1300 pages if I remember correctly–as part of the Ancient Christian Texts series by IVP.
I’m thinking about proposing to do some translation for a post doc here at Durham since we’re staying longer, so it’s good to see other work being done on him.
