Help me, Classical Music!
 

I need to know this answer, it's part of a radio quiz...

Okay, Í am told that a French composer has a last name of 6 characters starting with "R". It is titled something along the lines of "Ana Kreo", some Greek poet. Since I don't know the name of the poet,
I can only guess at the spelling, I can't find this on the net.

Any ideas to the French guys last name or the Greek's name?

Rameau?

Or possibly Gilles Raynal.
