How Sir Lamorak visited King Lot’s wife, and how Sir Gaheris slew her which was his own mother.
Now turn we unto Sir Lamorak, that much was there praised. Then, by the mean of Sir Gawaine and his brethren, they sent for their mother there besides, fast by a castle beside Camelot; and all was to that intent to slay Sir Lamorak.
