You are referring to Aristogoras who made a very good attempt to explain
observations of daily rotation and orbital motion using sunrise/sunset
for the former and seasonal declination for the latter -

"...just as Cleanthes thought it right that the Greeks collectively
should impeach Aristagoras the Stoic, of impiety, for overthrowing the
altar of earth, because the fellow attempted to account for visible
phenomena by supposing that the sky remains fixed, and that the earth
rolls round down an oblique circle, turning at the same time upon its own axis." Plutarch

When Copernicus shifted attention to direct/retrogrades of the slower
moving outer planets, then he converted the illusory loops into the
Earth's orbital motion and the normal temporary falling behind in view
all objects display as they are overtaken -

The perspective for the direct/retrogrades of the faster moving and
smaller circuits of Venus and Mercury originated in this forum as their
loops are actual and dictated by phase and size increases/decreases as
those planets approach and recede from the slower moving Earth -

Who do I give credit to ? - basically everyone from those who created
technological advancements to all the other perspectives that chopped and
changed over the thousands of years astronomers tried to make sense of
observations. That's the secret Collins, there is no need to talk down
human achievements or trying to squeeze observations into a Greek
framework so theorists can promote themselves as 'enlightened' while
ignoring everything else.

You can't explain the direct/retrogrades of Venus so don't give yourself
some status you don't have.


Completely wrong. I’m referring To Aristarchus of Samos the originator of
the heliocentric theory.

I can tell exactly when you changed or rather when you became desperate - it was the proof of the Earth's orbital motion which uses the transition of stars from left to right of the Sun thereby introducing a perspective that has been lost to RA/Dec observing. It must have been 4 or 5 years by now but instead of continuing in the productive direction you went full astern and ended up depending on contributors I wouldn't care to deal with.

By the way, Aristagoras in the passage of Plutarch is Aristarchus but there is an interesting aside to the use of his perspective on the dual motions of the Earth -

" It is a common misconception that the heliocentric view was held as sacrilegious by the contemporaries of Aristarchus. Lucio Russo traces this to Gilles Ménage's printing of a passage from Plutarch's On the Apparent Face in the Orb of the Moon. in which Aristarchus jokes with Cleanthes, who is head of the Stoics, a sun worshipper, and opposed to heliocentrism. In the manuscript of Plutarch's text, Aristarchus says Cleanthes should be charged with impiety. Ménage's version, published shortly after the trials of Galileo and Giordano Bruno, transposes an accusative and nominative so that it is Aristarchus who is purported to be impious. The resulting misconception of an isolated and persecuted Aristarchus is still transmitted today"

This is not trivia insofar as it shows how astronomers tried to put narratives together to account for observations. At least you will die knowing the difference between the illusory loops of the slower moving and greater circumferences of the outer planets are distinguished from the faster moving and smaller orbital circumferences of Venus and Mercury. In between these two perspectives is the orbital motion of the Earth and that is gives satisfaction to those who can appreciate how imaging makes all the difference.
