I wouldn't rule out that any individual might not see something in a moment of vision which spoke to them, and would be grounded in what they knew about, and that must have happened in the past as much as it happens now with ley lines and zodiacs. And visionaries may have recorded what they saw by markers in the landscape. But there's little proof of anything, more's the pity.

There was a very convincing television program recently about a valley in South America and representations of their star figures in the landscape. Or at least, it was convincing until they found an image representing Saturn as an old Eurpean type of man with a long beard. I wouldn't rule out that the odd European might not have washed up there before anyone recorded in history, but I find it unlikely that he would have influenced their astronomy so greatly.
