Recently came across a John Michael Godier video that contains an account of Aristotle observing a green star. My first thought was back to a radiolab episode that postulated that Homer had no word for the color blue, which is why he described the sea as 'wine colored.' I know a considerable amount of time exists between Homer and Aristotle, but would the latter have a word to describe the light of a blue star? Would blue have been recognized as a separate color in Aristotle's time?
