Desiderius Erasmus Roterodamus (/ˌdɛzɪˈdɪəriəs ɪˈræzməs/ DEZ-i-DEER-ee-əs irr-AZ-məs; Dutch: [ˌdeːziˈdeːrijʏs eːˈrɑsmʏs]; 28 October c. 1466 – 12 July 1536), commonly known in English as Erasmus of Rotterdam or simply Erasmus, was a Dutch humanist, Christian theologian, and philosopher. He was, through his writings, one of the most influential scholars of the Northern Renaissance and a major figure of Western culture.
Erasmus was an important figure in classical scholarship who wrote in a spontaneous, copious and natural Latin style. As a Catholic priest developing humanist techniques for working on texts, he prepared pioneering new Latin and Greek scholarly editions of the New Testament and of the Church Fathers, with annotations and commentary that were immediately and vitally influential in both the Protestant Reformation and the Catholic Reformation. He also wrote On Free Will, The Praise of Folly, The Complaint of Peace, Handbook of a Christian Knight, On Civility in Children, Copia: Foundations of the Abundant Style and many other popular and pedagogical works.
