Old Norse þula (pl. þulur) = 'a rote, old name for a kind of harp'
Þulur is now used for strings of rhymes running on without strophic division and of rhymed or alliterative formulas. The Þulur include wide areas of poetic vocabulary and give the names of gods, dwarfs, giants, valkyries, sea kings as well as synonyms for man, woman, weapons, battle, sea, ship etc. [1]
