Note 47 — CANTO XII. LOK PROCURES THINGS OF VALUE FROM THE DWARFS.
William Edward Frye translation
The new hair made for Sif may possibly represent a meteor, comet, or shooting star, or perhaps lightning, as connected with thunder (Thor). Finn Magnussen thinks that, in this mythe, Sif typifies the earth, and her hair the corn, which is cut down by Lok (time), and reproduced and gilded by him at the instigation of Thor; i.e. the electrical heat of summer ripening the corn.
