This is the first volume in the Amsterdam edition of the Latin texts of Erasmus of Ordo IV which comprises works on moral issues. It presents the panegyric of Philip the Fair, the father of Charles V, and the Education of Princes. Both works equally instruct princes how to behave morally. The third work in this volume treats language and praises the Word of God. The Latin texts are presented in a critical edition, accompanied by introductions and a commentary, elucidating difficult passages, tracing Erasmus’ sources and offering all linguistic, historical, theological and philological information needed to understand the text. The first two works are introduced and commented in German and the third work in French.
