A creature with a known cause
This page is unusual for this site, because the thing it describes is real and the physics are understood.
St Elmo's fire is a corona discharge: in a strongly charged atmosphere, usually during a storm, electricity leaks from a pointed conductor as a glow. A ship's mast is an excellent pointed conductor in the middle of an open sea. Sailors have been watching their rigging glow blue-violet for as long as there have been masts.
The lights seen over fields, paddy and marsh are a different phenomenon and a less settled one, usually explained by gases from decomposing organic matter igniting or glowing above wet ground.
So the santelmo is not an invention. It is an explanation — and the interesting question is not whether people saw something, but what they concluded about it.
What people concluded
That it is a soul.
In the Philippine accounts the fire is the spirit of a person whose death went wrong: the unburied, the drowned, the murdered, someone who died away from home or without rites. The same logic appears on half the pages of this site, from the rusalka to the tiyanak: a death that was not properly completed leaves something that cannot settle.
The fire does what such souls do everywhere. It appears at night, it is seen by people who are alone, it follows, and it draws the walker toward it. In some accounts it is simply there; in others it chases, and those versions are the ones people remember.
The saint in the name
The word is Spanish and the figure behind it is a Christian saint — Erasmus of Formia, San Telmo, patron of sailors. The glow on the mast was his sign, read by crews as protection or warning depending on when it appeared.
That name arrived in the islands on Spanish ships and then did something the sailors did not intend: it came ashore. A term for an electrical display at sea was attached to whatever lights people had already been seeing over their own fields and rivers, and the older local explanations for those lights were overwritten or absorbed.
The kapre page on this site is about a name imported with contempt. This one is about a name imported with a shrug, and it is the more common process of the two. A colonial language does not only bring insults; it brings vocabulary that quietly replaces what was there, and three centuries later the replacement is what everyone says.
Why it warns about water
Strip away the soul and the saint and the practical pattern is the same as the poludnitsa's or La Llorona's.
A light drifting over wet ground at night, seen by someone walking home alone, is a reason to go toward it. Marsh, paddy bunds, river edges and irrigation ditches are exactly where a person should not be walking in the dark, and they are exactly where these lights are reported.
A story that says do not follow the light is doing a job, and it is doing it in the places where following would cost most.
What we illustrate
A ball of light over a field, a light on water, and a moored boat with a bare mast. There is no face in the fire in the better accounts, and we have not put one there.

Frequently asked
What is a santelmo?
A ball of fire or light seen at night over fields, rivers, marshes and sometimes on the masts of boats. In folk accounts it is a soul — of the unburied dead, of someone who died by violence or drowning, or of a person whose death was not properly marked.
Is it a real phenomenon?
Two real phenomena, most likely. St Elmo's fire proper is an electrical discharge from a pointed conductor in a strongly charged atmosphere, which is why it appears on masts. Lights over marsh and paddy are usually attributed to ignited gases from decomposing matter. Neither explanation is folklore's business, and both are worth knowing.
Why does it have a saint's name?
Because sailors gave it one. Erasmus of Formia, San Telmo, is a patron of sailors, and the discharge on a mast was taken as his sign. Spanish ships brought the word to the islands, where it was attached to lights on land as well.
Is it dangerous?
The accounts say it follows people, and that it is drawn to those who are alone and in the dark. The practical danger in the reports is the obvious one: a light that leads a person off a path at night, into water or marsh.
How do you get rid of it?
Reported remedies run to the domestic and the improvised — dousing a lamp, keeping still, turning clothes inside out, prayer. The variation is wide enough that we do not present any single one as standard.
