("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. Role in Welsh tradition Culhwch ac Olwen, and Pa Gur yv y Porthaur 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. He arrives at his court at Celliwig but is denied by the Glewlwyd, the chief porter. Culhwch threatens to wreak havoc unless he is granted entry to the court and, eventually, Glewlwyd relents.

Glewlwyd is left with Llaesgymyn, "a man who was no use to anyone" as his sole remaining servant. Other appearances Glewlwyd is named twice in the Welsh Triads. He is listed as one of the twenty-four ordained knights of Arthur's court and is regarded as one of the "Three Offensive Knights of Arthur’s Court", alongside Sanddef and Morfran. They are known as the offensive knights because it is "repugnant to anyone to refuse them anything: Sanddef because of his beauty, Morfran because of his ugliness, and Glewlwyd because of his size and his strength and his ferocity." He is further named as the lover of Dyfyr Golden-Hair, one of the Three Famous Maidens of Arthur's Court. In The Lady of the Fountain, the tale
