h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Indubitably, old chap!

Took some time to ponder your question about Gallia Comata. (My latin is totally non existent so I need to consult others, dictionaries etc.) http://humanum.arts.cuhk.edu.hk/Lexis/Latin/ is a latin-english dictionary of some quality. There is no entry on "Gallia Comata" or just "Comata", but "Coma" is there and the definition is: coma : hair of the head. Seems to me the translation "long haired Gaul" is a sound one although I can't rule out the possibility that you may still be right. The use of certain words must be seen in their cultural context and may have slightly different meanings when dealing with fixed expressions etc.

From my Collins Latin Dictionary:

comatus a. long-haired; leafy. Gallia _____ Transalpine Gaul

Beyond that, you'll have to make your own assumptions (although the 'leafy' angle is intriguing).

could it really refer to some kind of camouflage....they lived in woods and marshes...........didn't they, the leafy ones?

Sounds like the long-haired translation is the right one, although picturing the leaf clad helmets and leafy branches tucked in their belts makes a more amusing spectacle. Modern armies need that kind of cover, but they do not (!) look intelligent while wearing it. (In Kirkenes some soldiers fed up with frontier service drove into the main street and camouflaged their huge truck with nets, branches and leaves. This happened outside the pub and the soldiers prepared to bivouaq inside the warm and cosy building. They were so well camouflaged I can't imagine how the police found them.) Sorry 'bout the not so ancient digression.....couldn't hep meself...
