No, Celine didn't write poetry that I know of. That's why I suggested Li Po instead. My list probably would have been something like Li Po, Pound, Jeffers, cummings, Catullus. But Buk knew Lawrence's prose and poetry. For example, Lawrence's poetry book Birds, Beasts and Flowers is echoed by Buk's Flower, Fist and Bestial Wail. And Bukowski wrote ALOT of poems, like Lawrence, about animals and humans' relationship to animals. And I think the long, Whitman-like line lengths in Lawrence influenced Bukowski. And he knew both Artaud's poetry and prose since he reviewed the Artaud Anthology which contains both.
But all this is up to debate. Ambreen, who do you think are Buk's favorite five poets?
