Note (11) — Chapter I
Reading edition
The earliest instance that I know of the use of the word Englaland is in the Treaty with Olaf and Justin in 991. Its earliest use in the English Chronicles is in 1014. See Norman Conquest, i. 78, 276, 605, 629. The oldest use that I know of the name Yorkshire (Eoforwicscír) is in the Chronicles under 1065. See Norman Conquest, ii. 478. Deira is, of course, as old as Gregory the Great’s pun.
