In the Canadian Army, a signaller is often referred to as a "Jimmy" in reference to the flag and cap badge feature Mercury (Latin: Mercurius), the winged messenger of the Roman gods, who is referred to by members of the corps as "Jimmy". The origins of this nickname are unclear. According to one explanation, the badge is referred to as "Jimmy" because the image of Mercury was based on the late medieval bronze statue by the Italian sculptor Giambologna, and shortening over time reduced the name Giambologna to "Jimmy". The most widely accepted theory of where the name Jimmy comes from is a Royal Signals boxer, called Jimmy Emblem, who was the British Army Champion in 1924 and represented the Royal Corps of Signals from 1921 to 1924.
