In Tennyson, a knight who had been suitor of Enide when her family was wealthy.
Geraint and Enide ended up lodging with Limours during their journey. Limours tried to convince Enide to abandon Geraint. Enide pretended to agree and advised Limours to take her by force in the morning. Returning to Geraint, Enide told her husband what had transpired, and the two fled Limours’s house. Limours chased after them but he was knocked unconscious in a fight with Geraint.
This figure appears in the Welsh Geraint as the Brown Earl. An individual named Limors appears later in Geraint. Tennyson seems to have taken the character from the former and the name from the latter.
