In Drakōn: dragon myth and serpent cult in the Greek and Roman worlds, Daniel Ogden discusses the "radical reinterpretation of Near-Eastern iconography" which may have formed the basis of some Greek myths: for example, images of Marduk vs Tiamat become the story of Perseus vs the sea-monster, Gilgamesh vs Humbaba becomes Perseus slaying Medusa, and the demoness Lamashtu portrayed with animals becomes Medusa "giving birth" to Pegasus. This is an interesting enough idea in itself, but the reason I mention it is Ogden's analogy: "We may invoke the model of the cult British stop-motion television series, The Magic Roundabout. Eric Thompson created this by watching the episodes of the French original, Le Manège enchanté, with the sound down, and spinning his own, whimsical narrations around the characters' ostensible actions, narrations that inevitably has little or no point of contact with the original stories." (A story which appears to be essentially correct. :)
