St. Elmo is the patron saint of which of the following?

I have actually seen St. Elmo's fire going up and down electrical power lines on a hot summer night. I woke up to the air crackling around my apartment and looked out to see what looked like glowing inch worms on the powerlines and the air was shimmering. Really eerie and beautiful.

Callie Rose, sounds fascinating. I'd very much like to see it, too.

Music muses are familiar with "St.Elmos' Fire"... The Band

if saint Elmo is patron Saint of sailors why there's Elmo as horror movie
