Firedrake

The term appears in Old English poetry as fyrdraca (attested in Beowulf) where it names a dragon-like monster; in later centuries the same compound vocabulary continued in English as "firedrake" and was applied both to dragons in poetic usage and to observed fiery aerial phenomena. Renaissance writers such as William Fulke (1563) record popular sightings treated as either supernatural (the Devil in dragon form) or explain them as natural vapors and meteors, showing the term's survival from medieval dragon-poetry into early modern attempts at meteorological explanation.

In the sky firedrakes are described as sparking streaks or shafts of fire, a golden stripe that sweeps across the evening sky, a flaming broom or sheaf, a fiery steelyard balance, or a glowing ball of blue fire releasing sparks. Swedish accounts emphasize a wingless 'worm-dragon' with no visible limbs; East Slavic descriptions include a long flaming shaft (Russian коромысло, 'fiery carrying pole') or a flaming broom. In Slavic narratives the same being may also appear on the ground in human shape and is said in some stories to enter houses through chimneys.

As aerial phenomena they display flight as streaks, brooms, shafts or balls of fire emitting sparks (often read as meteors or ignes fatui). In Slavic traditions the firedrake is agentive: it can shapeshift (air-serpent in flight; human guise on the ground), enter homes through chimneys, visit and seduce women at night—sometimes taking the form of a dead or absent husband—bring ephemeral gifts (reported to turn to horse manure at sunrise), inseminate women leading in stories to abnormal pregnancies and monstrous births, and cause wasting illness, mental disturbance, hallucination, and death. In Swedish and English contexts the phenomenon is more often ambiguous or interpreted as omen-like (devil or sign of Last Judgment) rather than consistently anthropophagous or vampiric.
