Иоанн Скилица
Genesius (, "Genesios") is the conventional name given to the anonymous Byzantine author of Armenian origin of the tenth century chronicle, "On the reign of the emperors". His first name is sometimes given as Joseph, combining him with a "Joseph Genesius" quoted in the preamble to John Skylitzes. Traditionally, he has been regarded as the son or grandson of Constantine Maniakes.
