 The discovery and publication of twelfth-century Byzantine scholia on Aristotle’s Physics and On Generation and Corruption (Rashed 2001, 2014) that preserve an elaborate cosmic time line for Love and Strife’s rule has further divided scholarly opinion. The scholia record an increase of Love’s power for sixty units of time; a perfect Sphere for forty units; and a rule of Strife lasting sixty units. Primavesi (2016) has linked this ratio to Pythagorean number philosophy through the structure of a double tetractys. Nonetheless, the authenticity of the scholia’s time line in relation to Empedocles’ philosophical system remains contested (Osborne 2005).
