. From the constancy of the stars, which is contrary to the mobility of the Earth, A. made a brilliant conclusion that they are so far that in comparison with the length of the path of the Earth around its axis no more than a point. Brave's theory Ahead of Copernican picture of the world, found no recognition in the ancient world (she came into conflict with astronomical observations), and Cleanthes even accused the author of impiety.
