   • Vǫluspá, verse 8, in 1867, S. Bugge, Norrœn fornkvæði: Sæmundar Edda hins fróða. Christiania, page 2:

     Tefldu í túni, / teitir váru
     var þeim vettugis / vant ór gulli;
     unz þrjár kvámu / þursa meyjar
     ámátkar mjök / ór jötunheimum

     They played games in the yard, / joyous were they
     to them was no / lack of gold;
     until three came / Troll-maidens
     very powerful / from Jotunheim
