sentences:  There are two extant books named "De Placita Philosophorum" (Περὶ τῶν ἀρεσκόντων φιλοσόφοις φυσικῶν δογμάτων, "Opinions of the Philosophers") and "Eclogae Physicae" (Ἐκλογαὶ φυσικαὶ καὶ ἠθικαί, "Physical and Moral Extracts").The first of these is Pseudo-Plutarch and the second is by Stobaeus.They are clearly both abridgements of a larger work.
