Reading edition
“Nimia tempestate acti ad insulam quæ Gersus vocatur,” says William of Jumièges. “Gersus” is a singular form for an island which is also called Cæsarea, but whose last syllable, like that of its neighbours, has a very Teutonic sound. Sir F. Palgrave (iii. 176) remarks that this is the first time that Jersey is spoken of in mediæval history. Wace (7937) seems to have thought that a special description of the position of his native island was needed;
“Gersui est prez de Costentin,
Là ù Normendie prent fin;
En mer est devers occident,
Al fiè de Normendie appent.”
