Gabriel (surnamed Severus)
a Greek prelate, born in Monembasia in 1577, was ordained bishop of Philadelphia, at Constantinople, by the patriarch Jeremiah. Seeing that his church containedt few Greeks, he withdrew to Venice, where he was bishop of the Greeks living there. His writings were published by Simon, under the title, Fides Ecclesiae Orientalis (in Greek, and Latin, 1671). They comprise two treatises, one relating to the sacraments, the other entitled Apologia, published for the first time at Venice in 1600. See Hoefer, Nouv. Biog. Generale, s.v.
