Note 534 — Chapter V · THE DANISH CONQUEST OF ENGLAND.[464] 975–1016.
Reading edition
Will. Malms, ii. 166. “Et de hominibus regis vel inimicis suis nullum Ricardus recipiat, neque rex de suis, sine sigillo eorum.” Sigillum does not necessarily imply a seal in the later sense; a signature of any kind is enough.
