constellation Draco
Nope; unrelated. "Caput Draconis" and "Cauda Draconis" are the old astronomical/astrological names for the "ascending" and "descending" nodes of the Moon, which of course move against the background of the fixed stars and thus cannot have anything to do with any constellation: their precession is in fact fairly heavily used and commented on in astrology.
So how exactly did "Draco" get into the nomenclature here? I don't know. -- Bill Thayer 41N53 87W38 col cuore a 42N59.5 12E42.4 alt.313m http://www.ukans.edu/history/index/europe/ancient_rome/I/home.html -
