Cf. Sir Gareth = "Beaumains"
Cf. Beren in The Silmarillion: as they escaped from Angband, the great wolf Carcharoth, whom Morgoth had personally bred, awoke. Beren held out the Silmaril, hoping that its radiance would avert the beast, but he was mistaken. Carcharoth bit off his hand, swallowing it along with the Silmaril, and proceeded to run rampant through Doriath. Thus Beren was called Erchamion, "One-handed".
