Bidental

In ancient Roman religion, a Bidental was a sacred spot erected on the location where lightning had struck. Any remains and scorched earth were to be burned in a hole at the location by priests called bidentales. Any person killed was to be buried in the earth where the lightning hit, as opposed to traditional cremation. A puteal (wellhead), or sometimes more than one, was then placed on the spot of burned earth. In order to further consecrate the spot, the head officiator would sacrifice a two-year-old sheep (called bidens). Finally, an altar was built, surrounded by a wall or fence to keep any trespassers away. Considered sacred, it was not to be touched, tread on, or even looked at after completion. Occasionally when falling into a state of decay, Bidentals would be repaired or reconstructed.

A Bacchic Roman puteal (wellhead) of the Neo-Attic style, inspired by Hellenistic art. Relief shows figures a Bacchic procession, with Hercules (in image), who, inebriated, wears the skin of the Nemean Lion and carries his olivewood club.

Places being struck by lightning were regarded as a terrifying example of godly wrath, and not to be taken lightly. Had any person committed sacrilege, they were punished severely with frenzy. Primarily it was believed that these shows of divine power were displayed specifically by Jupiter, King of the gods.
