Epicycles is what Copernicus fought against. Have he also have some I am not aware of ?!
Epicircle come about if one consider earth is the Center and some planets sometimes move backwards and then start to move forward again. You do not have that issues with Copernicus.
But he made a mistake of using circle. The observation guy using everything rotate around the sun and sun around the earth … a wrong model but the key is not the model but the observation he made. His record keeper Kepler finally found some other patterns and Newton get the … the rest is history.
I do not go to wiki or internet to check out the phrase. But epicircle …not of Copernicus.
