   • 9th century, First Merseburg charm:

     Eiris sazun idisi / sazun hera duoder;
     suma hapt heptidun / suma heri lezidun,
     suma clubodun / umbi cuoniouuidi:
     insprinc haptbandun / inuar uigandun.

     Once sat women,
     They sat here, then there.
     Some fastened bonds,
     Some impeded an army,
     Some unraveled fetters:
     Escape the bonds,
     flee the enemy!

The term's context in the Merseburg charm and its cognates suggest that the term may initially have had magical and/or poetic connotations.
