Eudemus of Rhodes (c. 370 BC - c. 300 BC) was an ancient Greek philosopher, considered the first historian of science. He was one of Aristotle's most important pupils, editing his teacher's work and making it more easily accessible. Eudemus' nephew, Pasicles, was also credited with editing Aristotle's works.

According to Damascius. Dubitationes et Solutiones de Principiis

125, V:

The Magi and the whole Iranian race call by the name Space or Time that which forms an intelligible and integrated whole from which a Good God and an Evil Demon were separated out, or as some say, light and darkness before these.
