(Βῶλος). Under this name Suidas, and Eudocia after him, mention a Pythagorean phiicropher of Mende, to whom they ascribe several works, which are otherwise entirely unknown. From this Pythagorean, Suidas distinguishes a Bolus who was a philosopher of the school of Democritus, who wrote on medicine and also an historical work. But, from a passage of Columella (7.5; comp. Stobaeus, Serm. 51), it appears that Bolus of Mende and the follower of Democritus were one and the same person; and he seems to have lived subsequently to the time of Theophrastus, whose work on plants he appears to have known.
