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.

Aberdeen Bestiary [c. 1200 CE]: "On a certain mountain in the east, there are fire-bearing stones which are called in Greek terrobolem; they are male and female. When they are far from each other, the fire within them does not ignite. But when by chance the female draws near to the male, the fire is at once kindled, with the result that everything around the mountain burns. For this reason, men of God, you who follow this way of life, stay well clear of women, lest when you and they approach each other, the twin flame be kindled in you both and consume the good that Christ has bestowed upon you. For there are angels of Satan, always on the offensive against the righteous; not only holy men but chaste women too."
Most illustrations show a man and a woman surrounded by flames, sometimes holding the stones; the burning stones alone are sometimes shown.
