Students of the Grail romances will remember that in many of the versions the hero—sometimes it is a heroine—meets with a strange and terrifying adventure in a mysterious Chapel, an adventure which, we are given to understand, is fraught with extreme peril to life. The details vary: sometimes there is a Dead Body laid on the altar; sometimes a Black Hand extinguishes the tapers; there are strange and threatening voices, and the general impression is that this is an adventure in which supernatural, and evil, forces are engaged.

enchantment can only be put an end to if a valiant knight will fight the Black Hand, and, taking a veil kept in the Chapel, will dip it in holy water, and sprinkle the walls, after which the enchantment will cease.
