In the course of editing and annotating Erasmus’ The Praise of Folly for the forthcoming Amsterdam edition of his complete works, I have come to believe that the 461 years since its first publication have produced only two original commentaries on the Moria. In 1515 a fairly thorough commentary, almost as long as the work itself and of a sort usually reserved for ancient works, was published with The Praise ofFolly. Reprinted eleven times during Erasmus’ lifetime, it has retained some currency, though not much, because it was reprinted in the Leyden Opera omnia of 1703-06. Though it goes under the name of Girardus Listrius, we know from one of Erasmus’ letters that he himself wrote part of it—how much we do not know. The second major commentary was that by I. B. Kan, published at The Hague in 1898. In our own century some useful information and suggestions have been provided by Maurice Rat and Hoyt Hudson. The rest, alas, is not silence, but (as Douglas Bush once said about Shakespearean criticism) fearless repetition.
