Lamantia’s first published poem [update 3/21, thanks to commenter Steven Fama: were five poems published in View in 1943: "I'm Coming," Apparition of Charles Baudelaire," "The Ruins," "By The Curtain of Architecture," and "There Are Many Pathways to the Garden."  He then sent some work to Breton, which was published in VVV.  Among these] was “Touch of the Marvelous”—the name already Fortean (or Ripleyan, if that neologism is acceptable).  The first lines are

“The mermaids have come to the desert
They are setting up a boudoir next to the         camel
Who lies at their feet of roses.”

These, too, have a Fortean ring.  But, capturing what Fort mean to Lamantia is not so easy.  The Fortean overtones in his other poems are less obvious; more to the point: as far as I know, he never wrote about Fort.  It’s possible to offer a plausible reconstruction, though.

Let’s start with surrealism.
