Henry Adams Bellows translation:

Then Heimdall spake, whitest of the gods,
Like the Wanes he knew the future well:

Makes it especially strange he's the only black norse god.

Which matters completely not because Heimdall from the mythology is not the same as the Marvel universe. I don't remember a alien being a ally with any norse gods.
