Svalinn

In Norse mythology, Svalinn is a shield which stands before the sun. It is attested in Grímnismál:

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
Svalin the shield is called,
which stands before the sun,
the refulgent deity:
rocks and ocean must, I ween,
be burnt,
fell it from its place. Grímnismál 38, Thorpe's translation
