Alectorius is a stone the size of a bean, clear as a crystal, and sometimes has veins the color of flesh. The stone is thought to come from a cock's throat. It renders its owner courageous and invincible, makes him wealthy, assuages thirst, and makes both husband and wife romantically amicable. But the stone's most amazing property is that it helps to regain a lost kingdom and acquire a foreign one. A.G.H.
