A book which provides readers with a critical text of both the ecphrasis of the church of the Holy Apostles by Constantine of Rhodes and his satyrical poems was still needed. De Stefani and Strano offer a new edition of these texts, while correcting several corrupted passages. Particularly, the debts of Constantine with his avowed model in the description of the church of Holy Apostles, Paul the Silentiary, have been highlighted and the imitations of Constantine's poems by later Byzantine poets have been registered. In fact Constantine is the scribe (J) of Paul's poems in the famous Pal. Heid. gr. 23. De Stefani in his edition of Silentiary's text pointed out several imitations of Silentiary by Constantine. Further imitations of Silentiary's poem came out in course of the elaboration of this project and are recorded in the fontes. Constantine's poem is wordly quoted by Georgius Cedrenus. This new very important tool would help to better both the text we are editing and the quotations by Cedrenus listed in the fontes. Finally, the apparatus of the fontes will also mention the most patent imitations of the poem of Constantine by later Byzantine poets. The book will be a useful tool for all students of Byzantine literature.
