LEO Grammaticus, a Byzantine historian of the tenth century, is said to have been governor of Cibyra under Constantine VII. His work, entitled Χρονογραφία τῶν τῶν βασιλέων περιχέων (A Chronography, comprising the Acts of the more recent Emperors), is a continuation of Byzantine history from the accession of Leo V., the Armenian, A.D. 813, to the death of Romanus I. in 948. Published along with Theophanes, under the superintendence of Combéfis, Paris, 1655, in the Parisian edition of the Corpus Historiæ Byzantinæ, it was reprinted at Venice, 1729. Leo probably wrote his History in the time of Romanus II.
