Glewlwyd Gafaelfawr

Glewlwyd Gafaelfawr ("Brave Grey Mighty Grasp") is a hero, warrior, and porter in tradition and Arthurian mythology, in which he appears as a knight in Arthur's retinue and chief gatekeeper of his court.

He is one of the earliest characters to be associated with Arthur and appears in a number of texts, including Culhwch ac Olwen, Geraint fab Erbin, Iarlles y Ffynnon, Pa Gur yv y Porthur and the Welsh Triads.

After being cursed by his stepmother such that he may marry no one but Olwen, daughter of the giant Ysbaddaden, Culhwch ap Cilydd seeks assistance from his cousin Arthur to win her hand in marriage.

Later on in Culhwch ac Olwen, Glewlwyd leads his servants during the hunt for the man-turned-boar, Twrch Trwyth, and three of them, Huandaw, Gogigwr and Penpingion, are killed in the process, mortally wounded by the quarry.

Glewlwyd is further mentioned in satirical fifteenth or sixteenth parody, Araith Iolo Goch, in which a certain "amorous-mannered, grief-pallored, pale-cheeked youth" from Gwynedd seeks the heart of a maiden from Powys.
