What do you mean by “available”?
Eg., I’m not interested in hearing that medieval philosophers ignored the idea that the motion of the planets are governed by the same laws that govern the motion of bodies on earth.
So, are we looking for something which is:
Simple,
True,
Not obvious,
Was claimed as true by someone or other,
But mostly ignored?
Perhaps Aristarchus and his heliocentrism would fit the bill (while not strictly true, it was truer than the alternative).
