But the favor of enchanters is short-lived and uncertain. Eliaures fell under the influence of a wicked woman, who, to satisfy her pique against Caradoc, persuaded the enchanter to fasten on his arm a serpent, which remained there sucking at his flesh and blood, no human skill sufficing either to remove the reptile or alleviate the torments which Caradoc endured.
Caradoc was betrothed to Guimier, sister to his bosom friend, Cador, and daughter to the king of Cornwall.

The vessels were to be placed three feet apart, and as the serpent crossed from one to the other. a knight was to cut him in two. If he failed in his blow,
