(Κωνσταντῖνος ὁ Κεφαλᾶς), was the compiler of the most important of the Greek Anthologies, the one which is known by the name of the Palatine Anthology. His personal history is entirely unknown, but in all probability his Anthology was composed at the beginning of the tenth century of our era. An account of the literary history of the Greek Anthology is given under Planudes.
