But this is relatively unimportant because Talos isn’t what Childress and von Däniken thought he was.
These authors primarily conceptualize Talos from his depiction in the 1963 Jason and the Argonauts movie, where he is a bronze automaton guarding a golden treasure.
He was of the stock of bronze, of the men sprung from ash-trees, the last left among the sons of the gods; and the son of Cronos gave him to Europa to be the warder of Crete and to stride round the island thrice a day with his feet of bronze. Now in all the rest of his body and limbs was he fashioned of bronze and invulnerable; but beneath the sinew by his ankle was a blood-red vein; and this, with its issues of life and death, was covered by a thin skin.
He had a single vein extending from his neck to his ankles, and a bronze nail was rammed home at the end of the vein. This Talos kept guard, running round the island thrice every day; wherefore, when he saw the Argo standing inshore, he pelted it as usual with stones. His death was brought about by the wiles of Medea, whether, as some say, she drove him mad by drugs, or, as others say, she promised to make him immortal and then drew out the nail, so that all the ichor gushed out and he died. But some say that Poeas shot him dead in the ankle.
On Cretan coins, Talos was neither bull nor robot, but a man with angel wings!
It probably would have been a good idea for alternative writers to check what the Cretans thought of Talos before assigning him the role of Gort from The Day the Earth Stood Still. In Crete, the word talôs meant “the sun,” which Hesychius of Alexandria confirms in his lexicon. On Crete “solar Zeus” was worshipped as Zeus Tallaios, identifying the god with the older Cretan solar figure. His orbit of Crete seems to derive from the sun’s daily transit, with the Greeks somewhat diabolizing the conquered Cretans’ sun god as a monstrous bronze bull—the symbol of the old Minoan gods. (This is little different from Christians turning the Classical gods into demons, or the Jews making the Mesopotamian heroes into giant monsters.)
(For those of you interested in this topic, I've added to my Library A. B. Cook's exhaustive survey of the history and origins of the Talos myth.)
So, in sum, we can see that the ancient texts clearly state that Talos was a living creature, and one that had a father and had children and therefore could not be a robot of any kind. The only way to make Talos into a robot is to declare that some parts of the stories are “true” while others are false, in contradiction to alternative authors’ stated claims that ancient peoples accurately recorded information about the past in their texts.
