Contemporary satellite observations, free from daily rotational influences with the ability to see planets as they actually exist within the framework of a Sun-centred system, obviate the need to appeal to the Ptolemaic framework which the first Sun-centred researchers were obligated to-
". . . the ancient hypotheses clearly fail to account for certain important matters. For example, they do not comprehend the causes of the numbers, extents and durations of the retrogradations and of their agreeing so well with the position and mean motion of the sun. Copernicus alone gives an explanation to those things that provoke astonishment among other astronomers, thus destroying the source of astonishment, which lies in the ignorance of the causes." 1596, Mysterium Cosmographicum

The appearance of the Pleiades is the 21st century version of Sirius as a dawn appearance for our ancestors as they are so recognisable.
Priority issues are silly, satellites are new and I have little regard for who is the first to promote the observations and conclusions - too busy looking for new angles and sharing information for others to join in. I would make the concession that I am a Christian as the more I look, the more I love-
" I answer, that a man should so stand free, being quit of himself, that is, of his I, and Me, and Self, and Mine, and the like, that in all things, he should no more seek or regard himself, than if he did not exist, and should take as little account of himself as if he were not, and another had done all his works."
