In Europe this association of the ram and its spiral horn played an even more obtrusive part.
The octopus as a surrogate of the Great Mother was primarily responsible for the development of the life-giving attributes of the spiral motif. But the close connexion of the Great Mother with the dragon and the thunder-weapon prepared the way for the special association of the spiral with thunder, which was confirmed when the ram with its spiral horn became the God of Thunder.

The Pig.
The relationship of the pig to the dragon is on the whole analogous to that of the cow and the stag, for it can play either a beneficent or a malevolent part. But the nature of the special circumstances which gave the pig a peculiar notoriety as an unclean animal are so intimately associated with the "Birth of Aphrodite" that I shall defer the discussion of them for my lecture on the history of the goddess.
Certain Incidents in the Dragon Myth.
Throughout the greater part of the area which tradition has peopled with dragons, iron is regarded as peculiarly lethal to the monsters. This seems to be due to the part played by the "smiths" who forged iron weapons with which Horus overcame Set and his followers,[231] or in the earlier versions of the legend the metal weapons by means of which the people of Upper Egypt secured their historic victory over the Lower Egyptians. But the association of meteoric iron with the thunderbolt, the traditional weapon for destroying dragons, gave added force to the ancient legend and made it peculiarly apt as an incident in the story.
