Now, observe how this dragon was pieced together mythologically. He is a storm cloud. He begins smaller than a man's hand and swells to huge dimensions; that characteristic of the howling storm was represented in the howling wolf Fenris of Norse Mythology, who was a little pet, a sort of lapdog for the gods at first, but when full grown broke the chains that tied him to mountains, and was only fettered at last by the thread finer than cobweb, which was really the sunbeam conquering winter. Then, when this worm was cut in two, the parts came together again. This feature of recurrence is especially characteristic of Hydras. In the Egyptian 'Tale of Setnau,' Ptah-nefer-ka saw the river-snake twice resume its form after he had killed it with his sword,--he succeeded the third time by placing sand between the two parts; and what returning floods taught the ancient scribe remained to characterise the dragon encountered by Guy of Warwick, which recovered from every wound by dipping its tail in the well it had guarded. The Lernean Hydra had nine heads, the Lambton Worm nine eyes and nine folds, and drank nine cows' milk. His fondness for the milk of cows connects him straightly with the dragon Vritra, whom Indra slew because he stole Indra's cows (that is, the good clouds, whose milk is gentle rain, and do no harm), and shut them up in a cavern to enjoy their milk himself. That is the oldest Dragon fable on record, and it is said in the Rig-Veda that beneath Indra's thunderbolt the monster broke up into pieces, and was washed away in a current of water. Finally, in being destroyed at last by razor blades, the dragon is connected with that slain by Ragnar, in whose armour the sun-darts of Apollo had turned to icicles. In the 'Death-Song of Ragnar Lodbrach,' preserved by Olaus Wormius, it is said that King Ella of Northumberland having captured that terror of the North (8th cent.), ordered him to be thrown into a pit of serpents. His surname, Lodbrach, or Hair Breeches, had been given because of his method of slaying a Worm which devastated Gothland, whose king had promised his daughter to the man who should slay the same. Ragnar dressed himself in hairy skins, and threw water over the hair, which, freezing, encased him in an armour of ice. The Worm, unable to bite through this, was impaled by Ragnar. Another version is that Ragnar killed two serpents which the King of Gothland had set to guard his daughter, but which had grown to such size that they terrified the country. It may be observed that the Lambton story christianises the Ragnar legend, showing that to be done in atonement for sin which in the other was done for love. The Cornish legend of St. Petrox has also taken a hint from Ragnar, and announces the rescue of christians from the serpent-pit in which the pagan hero perished. The icicles reappear on the slayer of the dragon of Wantley, represented by long spikes bristling from his armour.
