Fire stones

Latin name: Lapides igniferi

Other names: Cheroboli, Deus perres, Douze pierres, Lapides piroboli, Piroboli, Terrebolen, Terroboli, Turrobolen

Stones that burst into flames when brought close together

Found in the East, fire stones are either male or female. As long as they are kept apart, they are safe, but if a male and female stone are brought together, they ignite a fire that burns everything.

Men and women, particularly those in celibate monastic orders, should be kept separate, because lust burns when they are brought together.

Most illustrations show a man and a woman surrounded by flames, sometimes holding the stones; the burning stones alone are sometimes shown.
