), a Greek physician, who is called by Pliny (Plin. Nat. 20.32
) Petronius Diodotus,
though it is not unlikely that (as Fabricius conjectures) we should read Petronius et Diodotus,
as Petronius is distinguished from Diodotus by Dioscorides (De Mat. Med.
praef. p. 2), and S. Epiphanius. (Adv. Haercs.
1.1. 3, p. 3, ed. Colon. 1682.)
He must have lived some time in or before the first century after Christ, and wrote a work on botany.
