What reading level is Essays in Astronomy book?
To quickly assess the difficulty of the text, read a short excerpt:
It must have been known to the Egyptians and Chaldeans still earlier, if Pythagoras really acquired his knowledge of astronomy from them, as is affirmed by some of the ancient writers, but on that point there is no certainty. In public Pythagoras seemingly ac- cepted the current belief of his time, which made the earth the centre of the universe, but to his own chosen disciples he communicated the true doctrine that the sun occupies the centre of the solar system and that the earth is only one ...of the planets revolving around it. Like all the world's greatest sages, he seems to have taught only orally. A century elapsed before his doctrines were reduced to writ- ing by Philolaus of Crotona, and it was still later before they were taught in public for the first time by Hicetas, or as he is sometimes called Nicetas, of Syracuse. Then the familiar cry of impiety was raised, and the Pythagorean system was eventually suppressed by that now called the Ptolemaic, which held the field until it was overthrown by Copernicus almost two thousand years later.
