Michael Gabras
Michael Gabras was a Byzantine official and writer. A lowly scribe in the imperial chancery his life is relatively obscure except through his voluminous correspondence. "The most prolific of all Byzantine letter writers", according to Anthony Bryer, Gabras' 462 letters span the period 1305–1341, and his 111 correspondents include most of the major political and literary figures of his day. He also had a brother John, who wrote a theological treatise against the doctrines of Gregory Palamas.
