Frederick Cornwallis Conybeare is a somewhat enigmatic figure, both a bishop in the Roman Catholic Order of Corporate Reunion and a member of the Rationalist Press association of Freethinkers. He published widely on many topics, including the historical Jesus of Nazareth, setting himself against both traditionalist Christians and adherents to the Jesus-myth theory. This essay shows his technical mind in an analysis of Armenian translations of Plato's Apology that suggests new readings of the received Greek text. This is a solid piece of manuscript study that will interest philosophers, paleographers, and students of the Classics.
