  “Zeno’s argument is not correct, that any portion of millet  seed whatsoever makes a sound” (Arist. Ph.  7.5, 250a20–1). The version of this argument known to  Simplicius represents Zeno as engaged in a fictional argument with  Protagoras, wherein he makes the point that if a large number of  millet seeds makes a sound (for example, when poured out in a heap),  then one seed or even one ten-thousandth of a seed should also make  its own sound (for example, in that process) (Simp. in Ph.  1108.18–28). Aristotle’s report is too slight a basis for  reconstructing how Zeno may in fact have argued, and Simplicius is  evidently reporting some later reworking. The evidence nonetheless  suggests that Zeno anticipated reasoning related to that of the  sorites paradox, apparently invented more than a century later.
