Alshain: <interesting "Dog Star" info snipped> The astronomer Manilus,
in the first century CE, said about it that:
 
"Sirius (the Dog) will fashion unbridled spirits and impetuous 
hearts; it will bestow on its sons billows of anger, and draw upon 
them the hatred and fear of the whole populace... Their hearts start 
throbbing at the slightest cause, and when speech comes their tongues 
rave and bark, and constant gnashing imparts the sound of teeth to 
their utterance. Their failings are intensified by alcohol, which 
gives them strength and fans their savage wrath to flame." 
 
Does it sound like anyone in the HP-verse?
 
Kneasy: 
Good stuff. <snip> I've been patching together a not so serious post
on names which I must finish <snip>. One of those that I list is
Regulus, brother of Sirius. Regulus (trans. little king), brightest
star in the constellation Leo. 
Now I'd be interested in seeing how you could twist(!) the facts and 
mythology to suit a character that doen't seem very regal or
lion-like. Not trying to lure you into a pitfall, my post concentrates
on a different theme, but I would be entertained if you could do it.

Great post, Alshain! I'd be "entertained" (enlightened) if you'd do
one for Bellatrix (woman warrior?), which of course you know is a
bright star in the constellation Orion. (I'll bet Bella's Patronus is
an Amazon.)

Carol, with apologies for the short post
