International audience In a seminar on new thinking in school mathematics, held in Royaumont, France, in 1959, one of the main speakers, Jean Dieudonné, summarized the new school-mathematics programme he had in mind in the sentence: Down with Euclid. The purpose of the article is to analyse the context in which this quote was expressed and connect it to geometry teaching in Iceland where Euclidean geometry instruction seldom had a firm ground. Euclidean geometry in an amended version gained new interest in Iceland by the introduction of the New Math in the 1960s.
