I found this article in a history note and thought I would share, "Although he was the second president of the United States, John Adams was the first to (briefly) live in the presidential residence now known as the White House. That means he and his wife, Abigail, inaugurated such White House traditions as the selection of furnishings, the hosting of official gatherings, and the introduction of presidential pets — one of whom answered to the moniker of Satan. Despite the copious surviving correspondence between John and Abigail Adams, there exist few juicy details about this devilishly named dog for historians to sink their canines into. We do know that the pup shared the White House grounds with another mixed-breed named Juno (and possibly a third dog, named Mark). We can also deduce that Satan had to compete for the divided attention of the horse-loving president, who built the White House stables to house his carriage horses Cleopatra and Caesar. " I wonder if the pet dog's name refer to Saturn, Jupiter and Mars? and or Saturday, Thursday and Monday?
