Into the cave

The legend of the cave revolves around its namesake, St. Beatus, a monk living around 100 AD, who chose the cave in which to spend his pious hermitage. To his annoyance, however, he discovered someone was already living there; a horrible dragon, who shot lasers of fire from his blazing eyes. St. Beatus, however, would not be run out of his cave so easily, and held his cross up to the beast, invoking the Holy Trinity. Thrown into a hysteric fit, the dragon ran down the cliff and threw himself into Lake Thun below, causing the placid clear water to rise and boil.
