The Ingelrii swords, stylised as INGELRII, INGELRD or INGELRILT, were particularly highly prized by the Vikings. Other variations have also been found: INGRLRIIMEFECIT on a sword found ay Sigridsholm, Sweden, and INGELRIH FECIT on a sword found in Flemma, Norway. Probably crafted slightly later than the more frequently found ULFBERHT group of swords, they continued to be made until slightly later, that is, into the 12th century.
