The Siuru literary movement, named after a fire-bird in Finnic mythology, was founded in 1917 in Estonia.
Along with the founder August Gailit, the movement included the following young poets and writers: Marie Under, Henrik Visnapuu, Johannes Semper, Friedebert Tuglas, Peet Aren, Otto Krusten, and Artur Adson.
Mottos of the group included Carpe diem!, and May the joy of creation be our only moving force, the latter suggested by Friedebert Tuglas.
While her expressions of nature found a wide audience, her frank eroticism shocked conservatives, a motif she carried on in her subsequent works.
Adson went on to widely expand his genre, including dealing with social issues in a classical form.
