Ariston of *Ceos, *Peripatetic, probably succeeded *Lyco as head of the Lyceum c.225 bce. *Diogenes (6) Laertius appears to have derived from him the wills of *Aristotle and his successors, and a bibliography of *Straton (1). Gercke and Moraux assign to him Diogenes' bibliography of Aristotle, traditionally attributed to *Hermippus (2). Some reports may relate to him or to his Stoic namesake *Ariston (1) of Chios; a distinction between rational and non-rational soul seems to be his.
