The Prose Edda 1.32

"Forseti is the name of the son of Baldr and Nanna daughter of Nep: he has that hall in heaven which is called Glitnir. All that come to him with such quarrels as arise out of law-suits, all these return thence reconciled. That is the best seat of judgment among gods and men; thus it is said here:

A hall is called Glitnir, with gold 't is pillared, And with silver thatched the same; There Forseti bides the full day through, And puts to sleep all suits.
