(But all thys tyme kynge Arthure knew nat kynge Lottis wyff was his sister.) But thus
was the dreme of Arthure: hym thought there was com into hys londe gryffens and
serpentes, and hym thought they brent and slowghe all the people in the londe; and
than he thought he fought with them and they dud hym grete harme and wounded hym
full sore, but at the laste he slew hem.
