In Praise of Folly (Greek title: Morias Enkomion (?????? ????µ???) Latin: Stultitiae Laus sometimes translated as In Praise of More Dutch title: Lof der Zotheid) is an essay written in 1509 by Desiderius Erasmus of Rotterdam and first printed in 1511. The essay was inspired by De Triumpho Stultitiae written by Italian humanist Faustino Perisauli born at Tredozio near Forlì.
Erasmus revised and extended the work which he originally wrote in the space of a week while sojourning with Sir Thomas More at More's estate in Bucklersbury. In Praise of Folly is considered one of the most notable works of the Renaissance and one of the catalysts of the Protestant Reformation.
It starts off with a satirical learned encomium after the manner of the Greek satirist Lucian whose work Erasmus and Sir Thomas More had recently translated into Latin a piece of virtuoso foolery; it then takes a darker tone in a series of orations as Folly praises self-deception and madness and moves to a satirical examination of pious but superstitious abuses of Catholic doctrine and corrupt practices in parts of the Roman Catholic Church to which Erasmus was ever faithful and the folly of pedants (including Erasmus himself). Erasmus had recently returned disappointed from Rome where he had turned down offers of advancement in the curia and Folly increasingly takes on Erasmus' own chastising voice. The essay ends with a straightforward statement of Christian ideals.
