His works were first published under the title "Ἰωσὴφ μοναχοῦ τοῦ Βρυεννίου τὰ εὑρεθέντα δἰ ἐπιμελείας Εὐγενίου, Διακόνου τῆς Βουλγαρείας, ἤδη τὸ πρῶτον τύποις εκδόθεντα," three volumes, 8vo. Leipzig, 1768-1784. This edition contains only the Greek text. Eugenius, diaconus in Bulgaria, was in possession of a fine manuscript of the works of Bryennius, and he is the author of a life of Bryennius contained in the preface to the Leipzig edition.

The works of Bryennius were known and published in extracts long before the complete edition of them appeared. Leo Allatius refers to, and gives extracts from, several of his treatises, such as " Orationes II de Futuro Judicio et Sempiterna Beatitudine," in which the author maintained peculiar views respecting purgatory; "Oratio de Sancta Trinitate;" " Oratio de Transfiguratione Domini ;" " Oratio de Domini Crucifixione ;" &c.
