This volume in the ASD series (VIII, 1) publishes texts by Erasmus related to the Fathers of the Church. He himself considered this one of his major contributions to Christianity and the Church. He edited many Fathers and wrote Vitae of three theologians: John Chrysostom, Origen and, his most important one, Jerome. He gives a portrait of the theologians and his view on them, but also a kind of self-portrait. He also forged a text himself: ‘Cyprian’s De duplici martyrio’. His many editions of the Church Fathers and other theologians contain prefaces which provide us with information about the theologians, and with remarks on Erasmus’ view on them. Thus, we get a clearer view of Erasmus and his theology.
