Δαφνη Ευτυχια Αρθουρος

I only remembered that it was complex and scary-seeming the last time I'd looked, and had to look it up (http://en.wikipedia.org/wiki/Sestina) again to answer your question. It's six sextuplets and a triplet, and the words that end the lines of the first sextuplet have to be used to end the lines of the other sextuplets, but according to a particular pattern.

I'd feel safer writing a double-dactyl (but those tend to come out as cutesy as limericks, maybe not the right feel for this image).

And a confession: I don't think I've ever intentionally written a sonnet, either.
