Vera historia unionis non veroe inter Graecos et Latinos (Hagae Comitis, 1660, in folio),
was first published with a loose and florid version, by Robert Creyghton, chaplain to Charles II. in his exile. The zeal of the editor has prefixed a polemic title, for the beginning of the original is wanting. Syropulus may be ranked with the best of the Byzantine writers for the merit of his narration, and even of his style; but he is excluded from the orthodox collections of the councils.
