[118] _Transactions of American Philol. Assoc._ XXVIII. pp. 82-83. [119] Simplicius copies the same error in line 78, probably finding it in his copy of Empedokles. [120] Diels, _Doxographi Graeci_, p. 112, shows that Simplicius used the work of Alexander of Aphrodisias. [121] Cf. the correct form Simp. _Phys._ 159, 15; it is not unlikely that lines 52, 53 _ap._ 135, 21, and 132 _ap._ 39, 18 were also taken from Plato. [122] Four out of the six quotations from Herakleitos are given either in Plato or Aristotle, or both; Frag. 20 comes directly or indirectly from a Stoic source.
