Erevantsi, Melkhiseth (i.e., Melchisedech of Erivan), an Armenian doctor, was born in 1559 at Vejan. He early devoted himself to monastical life, and after studying under the famous doctor Nerses Peghlow about fifteen years, left his monastery, which was situated in the isle of Lim, in the centre of the lake of Van, in order to visit Armenia. He planted a great number of institutions of education, and returned to his monastery. The patriarch, Moses III, sent him out again as director of the patriarchal school of Echmiadzin. He died at Erivan in 1631, leaving several MSS. on grammatical, rhetorical, and philosophical subjects. See Hoefer, Nouv. Biog. Generale, s.v.
