collection, the nihilistic Sent på jorden (1932), a work hardly understood by his contemporaries. But Ekelöf moved towards romanticism and with his second poetry collection Dedikationen in 1934 he became appreciated in wider circles. He continued to write until his old age, and was to attain a dominant position in Swedish poetry. His style has been described as heavy with symbolism and enigmatic, while at the same time tormented and ironical. Another important modernist poet was Harry Martinson (1904–1978). Harry Martinson had an unparalleled feeling for nature, in the spirit of Linnaeus. As was typical for his generation, he wrote free verse, not bound by rhyme or syllable-count. He also wrote novels, a classic work being the partly autobiographical Flowering Nettles, in 1935. His most remarkable work was, however, Aniara, 1956, a story of a spaceship drifting through space. Arguably the most famous Swedish poet of the 20th century is Tomas Tranströmer (1931–2015). His poetry is distinguished by a Christian mysticism, moving on the verge between dream and reality, the physical and the metaphysical.

In a reaction against the experimental Sixties one in the Seventies took up the beat-tradition from the US, in a continued avant-garde effort which resulted in little magazines publishing poetry, a stencil movement out of which one of Swedish main poets of today – Bruno K. Öijer – grow, and developed a lyrical performance with inspiration from Antonin Artaud's "Theatre of cruelty", rock'n'roll and the avant-garde performance. Dan Andersson (born 6 April 1888 in Skattlösberg, Grangärde parish (in present-day Ludvika Municipality), Dalarna, Sweden, died 16 September 1920 in Stockholm) was a Swedish author and poet. He also set some of his own poems to music. Andersson married primary school teacher Olga Turesson, the sister of artist Gunnar Turesson, in 1918. A nom de plume he sometimes used was Black Jim. Andersson is counted among the Swedish proletarian authors, but his works are not limited to that genre. Drama Several writers of drama surfaced after World War II. In the
