Okay, 9th century means he's Tang, which means he should be in the Complete Tang Poems, which means if I can figure out how his name is spelled I should be able to find the original text. Or maybe it'd be better to search CTP for 刺猬, or maybe just 猬 since this is Classical Chinese ... :wanders off muttering:

ETA: Okay, found it, in a book of comic poems, under the title "Song of the Hedgehog" -- only in CTP it's credited to 李贞白, Li Zhenbai. Which is not surprising for Rexroth. At a quick glance, though the poem is at least roughly accurate -- here's a version with meanings when you hover over a character. I'll see if I can sot up a rendering. I'm not the poet Rexroth is, but it'll be fun to compare ...

ETA2: I did Rexroth a wrong -- the author is credited, in different texts, as both 李贞白/Li Zhenbai and 朱贞白/Zhu Zhenbai, the latter of which is rendered as Chu Chenpo in Wade-Giles transcription.
