Some of the earliest descriptions of the origin of the word 'Denmark', describing a territory, are found in the Chronicon Lethrense (12th century), Svend Aagesen (late 12th century), Saxo Grammaticus (early 13th century) and the Ballad of Eric (mid 15th century).
The Chronicon Lethrense explains how the Roman Emperor Augustus battled Denmark in the time of David,[REF] Denmark consisted of seven territories Jutland, Funen, Zealand, Møn, Falster, Lolland and Skåne which were governed by King Ypper of Uppsala.
