The frightful ugliness of the Gwrach y Rhibyn is a consistent feature of the superstition, in both its forms; it recalls the Black Maiden who came to Caerleon and liberated Peredur:[97] 'Blacker were her face and her two hands than the blackest iron covered with pitch; and her hue was not more frightful than her form. High cheeks had she, and a face lengthened downwards, and a short nose with distended nostrils. And one eye was of a piercing mottled gray, and the other was as black as jet, deep-sunk in her head. And her teeth were long and yellow, more yellow were they than the flower of the broom. And her stomach rose from the breast-bone, higher than her chin. And her back was in the shape of a crook, and her legs were large and bony. And her figure was very thin and spare, except her feet and legs, which were of huge size.' The Welsh word 'gwrach' means a hag or witch, and it has been fancied that there is a connection between this word and the mythical Avagddu,[98] whose wife the gwrach was.
