THE SCENE: Behold, a vision of Asgard, where Odin rules with his wife and also begets children with his daughter-wife.
THE TEXT: Then the sons of Bor built in the middle of the universe the city called Asgard, where dwell the gods and their kindred, and from that abode work out so many wondrous things, both on the earth and in the heavens above it. There is in that city a place called Hlidskjalf, and when Odin is seated there on his lofty throne he sees over the whole world, discerns all the actions of men, and comprehends whatever he contemplates. His wife is Frigga, the daughter of Fjorgyn, and they and their offspring form the race that we call Æsir, a race that dwells in Asgard the old, and the regions around it, and that we know to be entirely divine. Wherefore Odin may justly be called All-father, for he is verily the father of all, of gods as well as of men, and to his power all things owe their existence. Earth is his daughter and his wife, and with her he had his first-born son, Asa-Thor, who is endowed with strength and valour, and therefore quelleth he everything that hath life.”
