Eagle

Odin sought lodging for the night with a giant
called Baugi, Suttung’s brother. Baugi reckoned his economic
affairs were going badly, and said his nine slaves had killed each
other, and declared he did not know where he was going to get
workmen from. Odin told him his name was Bolverk; he offered
to take over the work of nine men for Baugi, and stipulated as his
payment one drink of Suttung’s mead.

[...]

Bolverk went to where Gunnlod was
and lay with her for three nights and then she let him drink three
draughts of the mead. In the first draught he drank everything out
of Odrerir, and in the second out of Bodn, in the third out of Son,
and then he had all the mead. Then he turned himself into the
form of an eagle and flew as hard as he could. And when Suttung
saw the eagle’s flight he got his own eagle shape and flew after
him. And when the Æsir saw Odin flying they put their containers
out in the courtyard, and when Odin came in over Asgard he spat
out the mead into the containers, but it was such a close thing for
him that Suttung might have caught him that he sent some of the
mead out backwards, and this was disregarded. Anyone took it
that wanted it, and it is what we call the rhymester’s share. But
Odin gave Suttung’s mead to the Æsir and to those people who
are skilled at composing poetry. Thus we call poetry Odin’s booty
and find, and his drink and his gift and the Æsir’s drink.’
