Dear SunWinkers:
There are two ways of classifying poems: One is by form: haiku, sonnet, villanelle, quatrain, rubaiyat, cubist, concrete, etc. The other is by purpose: elegy, ode, pastoral, epic, love poem, etc. One of the latter is, I suppose, inevitable: sooner or later, a dedicated poet of any accomplishment will feel the impulse to write about the poetic process, what a poem is, or what it should be. Such a poem is referred to as an ars poetica, which is Latin for “the art of poetry.” Possibly the most famous is Archibald MacLeish’s “Ars Poetica” :
(…)
A poem should be equal to:
Not true.
For all the history of grief
An empty doorway and a maple leaf.
For love
The leaning grasses and two lights above the sea—
A poem should not mean
But be.
SunWinks!
