From The Archives: The Krewe of Mercury 1985-2005 In Roman mythology, Mercury is the god of communication and transportation, and shares these traits with the Egyptian god Thoth, and the Grecian god Hermes, both of which also happen to be parading krewes. The Krewe of Mercury formed in 1985 and quickly became a popular parade in Jefferson Parish. In 2003, Mercury moved itself to what what was then known as Super Parade Sunday in Jefferson Parish (which has since evolved into the amusingly named Family Gras,) and shared the bill with the krewes of Rhea and Centurions. The krewe featured a series of family floats, mini-floats for the ladies of the court and the officers, and a special streetcar float for the ladies-in-waiting. The krewe was also known for attracting some of the more unique guest celebrities to ride with them. After Katrina the membership could no longer hold on and the Krewe of Mercury passed into Our Carnival Heritage.
