Alectorius (or Alectoria)
This stone is about the size of a bean, clear as crystal, sometimes
with veins the color of flesh. It is said to be taken from
the cocks stomach. According to ancient belief, it renders its
owner courageous and invincible, brings him wealth, assuages
thirst, and makes the husband love his wife, or, as another author
has it, makes the woman agreeable to her husband. Its
most wonderful property is that it helps to regain a lost kingdom
and acquire a foreign one.
