The Prose Edda 1.14

Then said Gangleri: "What did Allfather then do when Ásgard was made?" Hárr answered: "In the beginning he established rulers, and bade them ordain fates with him, and give counsel concerning the planning of the town; that was in the place which is called Ida-field, in the midst of the town. It was their first work to make that court in which their twelve seats stand, and another, the high-seat which Allfather himself has. That house is the best-made of any on earth, and the greatest; without and within, it is all like one piece of gold; men call it Gladsheim. They made also a second hall: that was a shrine which the goddesses had, and it was a very fair house; men call it Vingólf. Next they fashioned a house, wherein they placed a forge, and made besides a hammer, tongs, and anvil, and by means of these, all other tools. After this they smithied metal and stone and wood, and wrought so abundantly that metal which is called gold, that they had all their household ware and all dishes of gold; and that time is called the Age of Gold, before it was spoiled by the coming of the Women, even those who came out of Jötunheim. Next after this, the gods enthroned themselves in their seats and held judgment, and called to mind whence the dwarves had quickened in the mould and underneath in the earth, even as do maggots in flesh. The dwarves had first received shape and life in the flesh of Ymir, and were then maggots; but by decree of the gods had become conscious with the intelligence of men, and had human shape. And nevertheless they dwell in the earth and in stones. Módsognir was the first, and Durinn the second; so it says in Völuspá.

Then strode all the mighty to the seats of judgment, The gods most holy, and together held counsel, Who should of dwarves shape the peoples From the bloody surge and the Blue One's bones. They made many in man's likeness, Dwarves in the earth, as Durinn said.
