The Prose Edda 2.54

"How are the gods named? They are called Fetters, as Eyjólfr the Valiant Skald sang:

Eiríkr draws the lands beneath him At the pleasure of the Fetters, And fashions the Spear-Battle.

And Bonds, as Thjódólfr of Hvin sang:

The skilful God-Deceiver To the Bonds proved a stern sharer Of bones: the Helmet-Hooded Saw somewhat hindered seething.

Powers, as Einarr Tinkling-Scale sang:

I say, the Mighty Powers Magnify Hákon's empire.

Jólnar, as Eyvindr sang:

We have fashioned The Feast of Jólnar, The Prince's praise-song, Strong as a stone bridge.

Deities, as Kormákr sang:

The Giver of Lands, who bindeth The sail to the top, with gold-lace Honors him who pours Deities' verse-mead; Odin wrought charms on Rindr.
