    • Saint Elmo's fire a luminous, flamelike appearance, sometimes seen in dark, tempestuous nights, at some prominent point on a ship, particularly at the masthead and the yardarms. It has also been observed on land, and is due to the discharge of electricity from elevated or pointed objects. A single flame is called a Helena, or a Corposant; a double, or twin, flame is called a Castor and Pollux, or a double Corposant. It takes its name from St. Elmo, the patron saint of sailors.
