Book XIV - Chapter IX - How Sir Percivale promised her help, and how he required her of love, and how he was saved from the fiend.
THEN Sir Percivale promised her all the help that he might; and then she thanked him. And at that time the weather was hot. Then she called unto her a gentlewoman and bade her bring forth a pavilion; and so she did, and pight it upon the gravel. Sir, said she, now may ye rest you in this heat of the day.
