The setting of the manuscript is realistic: first of all, the reader can note the quotation of "the swan's road", because during the Middle Ages most of the trade and naval routs were named like animals or goods; then, the description of cliffs enlighted by the sun, deep crags and large promontories is typical of the coasts of Sweden and Denmark.

Indeed, the Anglo-Saxons took numerous voyages in the North of Europe and knew all the places quote very well.

Analysing "Beowulf", we get also information about voyages in the Middle Ages: the Anglo-Saxons sailed using  wood-weathered ships with vessel and gangplank.
