The Poet, Adelaide Crapsey, is best remembered for creating the cinquain. Crapsey (perhaps unfortunately named) was heavily inspired by the Japanese forms of poetry: haiku and tanka.
Much like the haiku, cinquains usually contain vivid imagery and are used to convey a certain emotion to the reader.
In 1915, Crapsey published a collection of poems called Verse. The book contained twenty-eight Cinquains, some of which are considered some of Adelaide Crapsey’s best work. If you want to see those, here’s a link for ya!
The cinquain has a relatively simple structure which, much like a haiku, relies on a number of syllables and lines.
