Note 782 — Chapter VIII · THE EARLY YEARS OF WILLIAM THE CONQUEROR.[497] A.D. 1028–1051. (continued 2)
Reading edition
Roman de Rou, 9144;
“De ço distrent li païsant,
E dient encore en gabant:
De Costentin iessi la lance
Ki abati le Rei de France.”
I have found the rhyme remembered in a Norman cottage, close by the field of Val-ès-dunes.
