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 as well!
In 2003, Mercury moved itself to what is now known as Super Parade Sunday in Jefferson Parish.  The krewe features 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 is also known for attracting some of the more unique guest celebrities to the Jefferson parish season.

The Krewe of Mercury shares a link with the krewes of Thoth and Hermes.

This krewe shares a Roman theme with the krewes of Aquila, Bacchus, Caesar, Centurions, Gladiators, and Saturn.

This krewe was stopped from marching in the 149th Carnival celebrations by Hurricane Katrina.  The krewe shares that bond with Adonis, Aphrodite, Arabi, Atlas, Bards, Choctaw, Cleopatra, Gladiators, Grela, Hermes, L'il Rascals,  NOMTOC, Oshun, Pegasus, Pontchartrain, Saturn, du Vieux, and  Crescent City.
