This volume in the ASD series (VIII, 1) publishes texts by Erasmus related to the Fathers of the Church. Erasmus himself considered these among 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 provides portraits of the theologians and his views on them, but also a kind of self-portrait. He even 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’ views on them. Thus, we get a clearer understanding of Erasmus and his theology.
