Refraction, reflection, refraction again,
light's path through moist droplets is bent.
Prismatic distortion through mist, fog or rain
from here on Earth it seems Heaven sent.
Though Science may understand how rainbows form
their multihued magic transcends
prosaic analysis after each storm,
when Nature is making amends.
Ancient mythologists from Nordic lands
believed they came down from Asgard.
Reaching out multiple polychrome bands,
linking that realm with Midgard.
Bearing the picturesque name "Rainbow Bridge"
this passage twixt Heaven and Earth
permitted the Gods to descend 'cross the ridge,
Loki was one, full of mirth.
Thor followed on with aggressive intent,
wielding his hammer called Mjolnir.
Odin the Archgod his passions gave vent,
riding his brave horse named Sleipnir.
The stout Rainbow Bridge carried traffic both ways
not just from Asgard to Midgard.
When fierce Viking warriors ended their days
Valhalla became their reward.
Their courage in battle would not be ignored,
their place midst the Gods they would claim.
Within the Great Hall their remains would be stored,
The Eddas would trumpet their fame.
