Seppo Ilmarinen, the Eternal Hammerer, blacksmith and inventor in the Kalevala, is an archetypal artificer from Finnish mythology. ("Seppo" is a popular boy's name and the Finnish word for smith "seppä" is derived from it, or vice versa.) Immortal, he is capable of creating practically anything, but is notoriously unlucky in love. He is described as working the known metals of the time, including brass, copper, iron, gold and silver. The great works of Ilmarinen include the crafting of the dome of the sky and the forging of the Sampo.
When the old sage, Väinämöinen, was traveling wide in the search of a wife, he was captured by the old mistress of Pohjola, the land of the North. In return for giving him safe passage from the land of Pohjola back to his native country, the enchantress Louhi of Pohjola wanted to have made the Sampo, a magic artifact. Väinämöinen replied that he could not make her one, but that Ilmarinen could, and promised to send the great smith to Pohjola to do just that. In return for this wondrous device, Louhi would also give Ilmarinen her daughter's hand in marriage.
On having returned home, Väinämöinen tries to awe Ilmarinen with tales of the maiden's beauty and so lure him to Pohjola. Ilmarinen sees through the ruse, however, and refuses. Not to be outdone, Väinämöinen tricks the smith into climbing a fir tree trying to bring down moonlight that is glimmering on the branches. Conjuring a storm-wind with his magical song, Väinämöinen then blows Ilmarinen away to Pohjola.
Once there, Ilmarinen is approached by the toothless hag, Louhi, and her daughter, the Maiden of Pohjola, and having seen the maiden's beauty, consents to build a Sampo. For three days, he sought a place to build a great forge. In that forge he placed metals and started working, tending the magic fire with help of the slaves of Pohjola.
On the first day, Ilmarinen looked down into the flames and saw that the metal had taken the form of a crossbow with a golden arch, a copper shaft and quarrel-tips of silver. But the bow had an evil spirit, asking for a new victim each day, and so Ilmarinen broke it and cast the pieces back into the fire.
On the second day, there came a metal ship from the fire, with ribs of gold and copper oars. Though beautiful to behold, it too was evil at heart, being too eager to rush towards battle, and so, Ilmarinen broke the magic boat apart and cast back the pieces once more.
On the third day, a metal cow emerged, with golden horns and the sun and the stars on its brow. But alas, it was ill-tempered, and so the magical heifer was broken into pieces and melted down.
On the fourth day, a golden plow is pulled from the forge, with a golden plowshare, a copper beam and silver handles. But it too is flawed, plowing up planted fields and furrowing meadows. In despair, Ilmarinen destroys his creation once more.
Angered at his lack of success, Ilmarinen conjures the four winds to fan the flames. The winds blow for three days, until finally, the Sampo is born, taking the shape of a magic mill that produces grain, salt and gold. Pleased with his creation at last, Ilmarinen presents it to Louhi, who promptly locks it in a vault deep underground.
Returning triumphant to the Maiden of Pohjola, Ilmarinen bids her to become his wife. To his dismay, she refuses to leave her native land, forcing him to return home alone and dejected.
After the loss of his first wife to Kullervo's curse, the disheartened Ilmarinen attempts to craft a new one from gold and silver, but finds the golden wife hard and cold. Dismayed, he attempts to wed her to his brother Väinämöinen instead, but the old sage rejects her, saying that the golden wife ought to be cast back into the furnace and tells Ilmarinen to "forge from her a thousand trinkets". Speaking to all of his people, he further adds:
"Every child of Northland, listen,
Whether poor, or fortune-favored:
Never bow before an image
Born of molten gold and silver:
Never while the sunlight brightens,
Never while the moonlight glimmers,
Choose a maiden of the metals,
Choose a bride from gold created
Cold the lips of golden maiden,
Silver breathes the breath of sorrow."
The tale of the Golden Wife can be seen as a cautionary tale based on the theme of "money cannot buy happiness". To a contemporary reader, there is also a similarity to the hubristic nature of the Golem legend, or to Frankenstein, in that even the most skilled of mortals cannot rival divine perfection when creating life.
