Résumé :
Ms. Paris, BnF, grec 400 is a treasure-trove of little-known texts, including model letters, homilies and poems composed in Cyprus, which has been oddly overlooked in studies of Greek culture and literature under the Lusignans. This paper consists of four parts: (i) the date, provenance and composition of the manuscript; (ii) its poetic contents; (iii) the social function of the paraenetic poems it contains; and (iv) an edition of a hitherto unknown collection of paraenetic poems, Στίχοι τοῦ ἁγίου Γρηγορίου τοῦ Θεολόγου ἐκ τῶν γνωμικῶν, probably dating from the thirteenth century.
