Cymochles.
A man of prodigious might, brother of Pyrochls, son of Malice (Acrats) and Despite, and husband of Acrasia, the enchantress. He sets out to encounter Sir Guyon, but is ferried over the idle lake by Wantonness (Phædria), and forgets himself; he is slain by King Arthur (canto viii.). The word means, one who seeks glory in troubles. (Spenser: Faërie Queene, ii. 5.)
