Happened to be reading Kalevala one day and noted that there is a full rune (poem) about history of technology - namely, the origin of iron. In it, the sage Väinämöinen sings how iron came to be, and why it broke its solemn oath to its "founder," blacksmith Ilmarinen, not to harm people or serve as a tool of war: (hint: it was the bees' fault, and serves also as a first lesson why you want to have quality control protocols with your suppliers and subcontractors.)

By the furnace, by the anvil,

By the tongs, and by the hammer,

These the words he vowed and uttered:

'Many trees that I shall injure,

Shall devour the hearts of mountains,

Shall not slay my nearest kindred,

Shall not kill the best of heroes,

Shall not wound my dearest brother;

Better live in civil freedom,

Happier would be my life-time,

Should I serve my fellow-beings,

Serve as tools for their convenience,

Than as implements of warfare,

Slay my friends and nearest. kindred,

Wound the children of my mother.

You can read the entire poem here; the 1888 translation is fairly decent here and actually easier to follow than the original Finnish, even for a native Finn...

Now, the question: As a sort-of historian of technology in a need for morale boost every now and then, I'm obviously tempted to drop this example of "Väinämöinen, the first (Finnish) historian of technology" in some future lecture or somesuch. But since my grasp of world's mythology, lore and legends is quite spotty at best, and since this is an interesting topic to me, I thought to query the fount of knowledge here about what do other mythologies have to say about history or origin of technology or of particular technologies, like iron, farming, etc.?

Edited for clarity.
