Cosmological and Philosophical Texts

Ancient and classical works whose primary content is a cosmological or philosophical system with esoteric resonance rather than a ritual or magical practice, Ptolemy's Almagest, Kepler's Harmonices Mundi, Nicomachus's Introduction to Arithmetic, Plotinus's Enneads, the Pythagorean Golden Verses and Plato's Timaeus. These sit apart from the Hermetic Texts grouping nearby, whose works claim a more explicitly revelatory or magical origin rather than a philosophical one.
