In Spain, several prominent poets experimented with haiku, including Joan Alcover, Antonio Machado, Juan Ramón Jiménez and Luis Cernuda. Federico García Lorca also experimented with and learned conciseness from the form while still a student in 1921. The most persistent, however, was Isaac del Vando, whose "La Sombrilla Japonesa" (1924) went through several editions. The form was also used in Catalan by the avant-garde writers Josep Maria Junoy (1885–1955) and Joan Salvat-Papasseit, by the latter notably in his sequence "Vibracions" (1921).
