What are the longest words of Greek?

Everyone knows (or should know) about the longest word of Greek ever—the word that broke the title bar of Wikipedia, Aristophanes' fantastical dish of 17 ingredients at the end of the Ecclesiazusae, that lopado-temacho-thing:

λοπαδοτεμαχοσελαχογαλεοκρανιολειψανοδριμυποτριμματοσιλφιολιπαρομελιτοκατακεχυμενοκιχλεπικοσσυφοφαττοπεριστεραλεκτρυονοπτοπιφαλλιδοκιγκλοπελειολαγῳοσιραιοβαφητραγανοπτερυγών (172 chars)

Ah. It breaks blogspot too. :-)

λοπαδοτεμαχοσελαχογαλεοκρανιολειψανοδριμυποτριμματοσιλφιο­λιπαρομελιτοκατακεχυμενοκιχλεπικοσσυφοφαττοπεριστεραλεκτρυονοπτο­πιφαλλιδοκιγκλοπελειολαγῳοσιραιοβαφητραγανοπτερυγών (172 chars)

Have you ever wondered what the next longest words of Greek are? No? Well, you'll find out anyway. With the necessary provisos as usual:

• I'm basing this on the word forms in the current TLG, and the lexica I have access to—LSJ, LSJ Supplement, Lampe, Trapp, Kriaras.
  
• This doesn't prove much of anything, since the point is that Greek compounding is agglutinative and productive, so you can keep stringing words up. We're just happening to go through the long words turning up in Ancient and Mediaeval Greek literature.
  
• Do not even think of coming away with the impression that Greek literature makes the longest words in the world—although few if any seem to get anywhere near Aristophanes' monster. The Guinness Book of Records did unearth a word in the Varadambika Parinaya by Tirumalamba in Sanskrit adding up to 428 letters in Roman transliteration. I can't find it (I think this is the Google Books snippet); which is a shame, I wanted to break Blogspot some more...
  
• For other languages, have a Facebook thread and a Wikipedia laundry list.
  
• I'm sure there's plenty of compounding happening in Modern Greek; I cited in the Quadrupeds (p. 150) the Hellas-L coinage πολυμαθουφοχριστιανοπεοκρουστόπαιδο "polymath UFO Christian penis-stroking lad" (35 chars), which maker poster Constantine Thomas coiner of the sixth longest real Greek word I know of. That… doesn't prove that much either.

What it shows is, there was a Byzantine fad for long compounds, in a couple of genres, though possibly ultimately indebted to Aristophanes; and Aristophanes himself went there more than once.

I'm going to count down the top 40-odd words in length I can find, down to a length of 29 characters, and I'll give their dictionary definitions (where available) and who has used them.

The longest words in English, long enough to be cheating, are protein names. The longest words in Greek outside of Aristophanes, long enough to be cheating, are fractions. They're so boring, dictionaries don't bother to list them at all. So I'm putting them separately:

And now, the "real" words. Words not (yet) in the TLG are asterisked.

1. κεραυνομεγακλονοζηνπερατοκοσμολαμπροβελοπλουτοδότα (50 chars), (Luis Muñoz Delgado, Léxico de Magia y Religiòn en los Papiros Mágicos Griegos, 2001) "making great noise with a thunderclap, bounded by the sky, shining rays in the cosmos, and giver of wealth", Magical Papyri 12. The magical papyri have even longer strings of nonsense characters, but this really does count as a word. It's worth taking it apart:
   
   • κεραυνο "thunder"
   • μεγα "big"
   • κλονο "turmoil"
   • ζην "Zeus"
   • περατο "boundary"

   • ἀκτινο "ray"
   • χρυσο "gold"
   • φαιδρο "beaming"
   • βροντο "thunder"
