I checked Aristotle's 'On the Heavens' and 'Physics'. Nowhere could I find him saying that a heavy object falls faster than a light one. Aren't it the Aristotelian scholars who said that and who are to blame? Aristotle distinguished relative weight (our mass) and absolute weight (our mass density) and gives practical examples to check that denser objects move faster downwards in water than less dense objects, if the objects have the same shape.
