A hermit living near Windsor, he hosted Lancelot when the latter left Arthur's court in London after a quarrel with Guenevere. It was this quarrel that led to the dinner at which Sir Patrise was poisoned, for Guenevere gave the dinner

to show outward that she had as great joy in all other knights of the Round Table as she had in Sir Lancelot.

Brasias probably is to be identified with Sir Brastias.
