The only unidentified poem in Kenneth Rexroth, Poems from the Greek Anthology.
Expanded Edition...Introduction by David Mulroy (Ann Arbor: University of Michigan Press, 1999; rpt. 2002), is the following (p. 10):
I know I am poor,
Neither do I have to be reminded
Of my own name or
the day of the week.
All your bitterness will get us nowhere.
Wash the anchovies
While I pour the wine.
Naked and drunk, we'll find riches in bed.
Neither Mulroy in his Index (pp. 113-114) nor Otto Steinmayer, Bryn Mawr Classical Review 2000.11.06
, was able to track down the original. I can't either.
