Svalinn heitir, hann stendr sólu fyrir, skjöldr, skínanda goði; björg ok brim, ek veit, at brenna skulu, ef hann fellr í frá. - Grímnismál 38, Guðni Jónsson's edition
Svalinn is his name, he stands a shield before the sun, the shining deity. I know that the hills and the sea would burn, if it were to fall from its place. - Grímnismál 38, William Herbert's translation
