Each in his own right a truly great poet, Tu Fu and
Li Po were also the best of friends: spending time together, writing poems to each other, and generally greatly enjoying each others company. Both are remembered as wonderful Taoist poet-sages, still here sharing, through their written words, their intimate playful wisdom. Enjoy!
One contemporary example of a similar poetic collaboration is that between Ted Kooser and Jim Harrison -- as recorded in their co-authored collection Braided Creek: A Conversation In Poetry. The two poets intentionally keep us guessing, in this collection, about which poems were written by whom -- which I found to be a lovely gesture. I mean, sure -- it's nice to have ones work acknowledged, for emotional as well as, every now and again, financial reasons. But ultimately, does it really matter whose mouth the words happen to flow out of?
