The Prose Edda 2.25

"How should one periphrase the sea? Thus: by calling it Ymir's Blood; Visitor of the Gods; Husband of Rán; Father of Ægir's Daughters, of them who are called Himinglæva, Dúfa, Blódughadda, Hefring, Udr, Hrönn, Bylgja, Bára, Kolga; Land of Rán and of Ægir's Daughters, of Ships and of ships' names, of the Keel, of Beaks, of Planks and Seams, of Fishes, of Ice; Way and Road of Sea-Kings; likewise Encircler of Islands; House of Sands and of Kelp and of Reefs; Land of Fishing-gear, of Sea-Fowls, and of Fair Wind. Even as Ormr Barrey's-Skald sang:

On the gravelly beach of good ships Grates the Blood of Ymir.

As Refr sang:

The mild deer of the masthead beareth O'er the murky water from the westward Her wave-pressed bows; the land I look for Before the beak; the Whale-Home shallows.

Even as Steinn sang:

When the fallow fell-wall's Whirlwinds Wove o'er the waves full fiercely, And Ægir's storm-glad daughters Tore, of grim frost begotten.

And as Refr sang:

Gymir's wet-cold Spae-Wife Wiles the Bear of Twisted Cables Oft into Ægir's wide jaws, Where the angry billow breaketh.

It is said here that Ægir and Gymir are both the same. And he sang further:

And the Sea-Peak's Sleipnir slitteth The stormy breast rain-driven, The wave, with red stain running Out of white Rán's mouth.

As Einarr Skúlason sang:

The stern snow-wind has thrust out With strength, the ship from landward: The Swan-Land's steed sees Iceland Into the surf receding.

And as he sang further:

Many a stiff rowlock straineth, And the noisy Strand of Fish-Gear, The Sea, the lands o'ercometh: Men's hands oft span the stays.

And he sang yet further:

The gray Isle-Fetter urges Heiti's raven-ship onward; Gold beaks the fleet ships carry: Rich that faring to the Chieftain.

And he sang again:

The Isle-Rim autumn chilly Impels the dock's cold snowshoe.

And thus also:

The cool lands' Surging-Girdle Before the beaks springs asunder.

As Snæbjorn sang:

They say nine brides of skerries Swiftly move the Sea-Churn Of Grótti's Island-Flour-Bin Beyond the Earth's last outskirt,— They who long the corny ale ground Of Amlódí; the Giver Of Rings now cuts with ship's beak The Abiding-Place of boat-sides.

Here the sea is called Amlódi's Churn.

As Einarr Skúlason sang:

The sturdy drive-nails weaken In the swift swirl, where paleth Rakni's Heaving Plain: wind Puffs the reefs against the stays.
