Eysteinn (Swedish:
Östen; died ca 600) was the son of
Eadgils and
Yrsa of
Saxony. He was the father of
Ingvar. The Eysteinn tumulus
(Östens hög) in
Västerås near Östanbro has been linked to King Eysteinn by some popular historians. The term Hög is derived from the
Old Norse word
haugr meaning mound or barrow.
