Portuguese Experimental Poetry, claiming to be an avant-garde movement, arose in Lisbon in the mid 60’s. It got its name from the title of a magazine, Cadernos de Poesia Experimental, which became the herald of the movement. Two issues were published, the first in 1964 and the second in 1966, organized by António Aragão and Herberto Hélder. The first issue was presented as anthological, since it included texts not only of Portuguese poets and musicians but also Brazilian, French, Italian and English artists. It also had a section which included poets of several epochs and tendencies, such as Luis de Camões or Quirinus Kuhlmann, representing respectively the mannerist and baroque aesthetics of European poetry.
