In November 1881 Jacques Perk (born 1860) died. He was no sooner dead, however, than his posthumous poems, and in particular a cycle of sonnets called "Mathilde", were published (1882) and awakened extraordinary emotion. Perk had rejected all the formulas of rhetorical poetry, and had broken up the conventional rhythms. There had been heard no music like his in the Netherlands for two hundred years. A group of young men collected around his name and were joined by the poet-novelist-dramatist Marcellus Emants (1848–1923). Emants had written a symbolical poem called "Lilith" in 1879 that had been stigmatised as audacious and meaningless; encouraged by the admiration of his juniors, Emants published in 1881 a treatise in which the first open attack was made on the old school.
