From the testimonies offered by Aetius there is also an astronomical interest in Alcmaeon, but more than original hypotheses would have welcomed some interpretations of his time, for example by Heraclitus and Antiphon of Athens shared that the lunar eclipse comes from the different inclination of its cavity as the stars [5], [13]. of that metaphor than that his views were typical Greek views on contrary motions, which imitate the contrary motions of the fixed scholarship about his originality.
