Um... "historical rendition depicting Santa's reindeer"? *BG* I assume you mean the history of the rendition and not of the subject matter!

Lemme get this straight: We're talking about flying reindeer – one with a glowing red nose – who live at the North Pole with Santa Claus and his elves at their workshopuntil the reindeer pull Santa's sleigh through the air around the world as they land on the rooftop of every house in the world and wait for Santa to go down the chimney and leave toys and go back up the chimney and do all this in one night...

...and we are trying to determine the gender of the reindeer based on facts about wildlife?
