The Prose Edda 2.37

"Gold is called Freyja's Tears, as was said before. So sang Skúli Thorsteinsson:

Many a fearless swordsman Received the Tears of Freyja The more the morn when foemen We murdered; we were present.

And as Einarr Skúlason sang:

Where, mounted 'twixt the carvings, The Tear of Mardöll lieth, We bear the axe shield-splitting, Swollen with Serpent's lair-gold.

And here Einarr has further periphrased Freyja so as to call her Mother of Hnoss, or Wife of Ódr, as standeth below:

The shield, tempest's strong roof-ice, With tear-gold is unminished, Eye-rain of Ódr's Bed-Mate: His age the King so useth.

And again thus: :Hörn's Child, the glorious adornment, :I own, gold-wound—a jewel :Most fair—to the shield's rim :Fast is the golden Sea-Flame: :On the gem, Freyr's Niece, the tear-drift :Of the fore-head of her Mother :She bears; the Raven-Feeder :Gave me Fródi's seed-gold's fostering.

It is also recorded here that one may periphrase Freyja by calling her Sister of Freyr.

And thus also:

A defence of songs full goodly He freely gave me, neighbor Of sea-scales: I praise gladly Njördr's Daughter's golden gem-child.

Here she is called Daughter of Njördr.

And again thus:

The awesome Stately Urger Of Odin, he who raises The struggle stern, gave to me The courage-stalwart daughter Of the Vana-Bride, my fair axe; The valorous sword-mote's Ruler Led Gefn's girl to the Skald's bed, Set with the sea-flame's gold-work.

Here she is called Gefn and Bride of the Vanir.—It is proper to join 'tears' with all the names of Freyja, and to call gold by such terms; and in divers ways these periphrases have been varied, so that gold is called Hail, or Rain, or Snow-Storm, or Drops, or Showers, or Water falls, of Freyja's Eyes, or Cheeks, or Brows, or Eyelids.
