I too love riddles and kennings, and I've written about them on this blog before. The Vikings thought more of a man if he could weave words: some of their most renowned warriors were also poets, like Iceland's Egil Skallagrimsson, and Grettir the Strong. The murderous Harald Silkenhair in 'West of the Moon' is a warrior poet from this tradition, and keeps his men happy by asking them riddles (here are two I made up for him):
“I know a stranger, a bright gold-giver
He strides in splendour over the world’s walls.
All day he hurries between two bonfires.
“I know another, high in the heavens
Two horns he wears on his hallowed head
A wandering wizard, a wild night-farer,Sometimes he feasts, sometimes he fasts.”
