The Prose Edda 2.61

"What are the names of fire? Even as is written here:

Not seldom does the fire blaze Which Magnús sets: the stalwart Ruler burns habitations: Houses blow reek before him.

Glow, as Valgardr sang:

Fierce Glow, with red-hot embers, Swiftly from the soot flared, Straight o'er the tottering dwellings Stood up the dense smoke-columns.

Bale, as here:

Haki was burned on Bale, Where the sea's broad wake weltered.

Gledes, as Grani sang:

I think the Gledes diminished . . . Glammi's tracks; thus the king kindled.

Embers, as Atli sang:

With blood the axe is reddened, Embers wax, burn many houses, Halls stand aglow; now rages The Gem; good men are falling.

Here fire is called Gem also.

Vapor, as here:

Half-built, by the Nid's side Burn the All-Ruler's dwellings; I think fire razed the hall's pride: Vapor shot rime on the people.

Hot Ashes, as Arnórr sang:

The Isle-Danes' wrathful Harmer With the Raumar spared not hard counsel: Hot Ashes made them calmer; The Heinir's threatening words hushed.

Flames, as Einarr sang:

Flame soon was alight, And swiftly took flight All Hísing's host: The fight they lost.

Flare, as Valgardr sang:

The sturdy king's bright Flare soared Above the castle's bulwark; The vikings burst in grimly: Grief on the maid descended.

Lowe, as Haldórr sang:

There did ye share their jewels, While o'er the host the Shield's Lowe, The sword, shrieked fiercely: never Wert thou spoiled of conquest.
