Arsenius, Anristobulus archbishop of Monembasia, or Malvasia, in the Morea, was born near the middle of the 15th century. He was the son of Michael Apostolius, and was a distinguished scholar and philologist. Excommunicated by the patriarch of Constantinople for his alliance with Rome, he sought refuge in Venice, where he died in 1535. We are indebted to him for a very rare book, entitled Prceclara Dicta Philosophorum, Imperatorum, Oratorum, et Poetarum (Rome, s. a.). He also wrote Greek scholia on seven tragedies of -Euripides, dedicated to Paul III (Venice, 1534). See Hoefer, Nouv. Biog. Generale, s.v.
