and in Ed. Rom. (1471); the others have labefacta.  Orelli’s statement (note to his separate text of the Academica 1827) that Cic. commonly uses the perfect labefeci and the part, labefactus is quite wrong.  The former is indeed the vulg. reading in Pro Sestio 101, the latter in De Haruspicum Responsis 60, but the last of these two passages is doubtful.  Cic. as a rule prefers long forms like sustentatus, which occurs with labefactatus in Cat.  Mai. 20.  For the perfect labefactavit cf.  I. 33. Agam igitur:  Cic. rather overdoes the attempt to force on his readers a belief in the learning of Lucullus.

Sec.11. Pro quaestore:  cf. 4. Essem:  MSS. issem, whence Goer. conj. Alexandriam issem. Heraclitus Tyrius:  scarcely known except from this passage. Clitomachum:  for this philosopher see Zeller 532. Quae nunc prope dimissa revocatur:  sc. a Cicerone.  Philo’s only notable pupils had combined to form the so called “Old Academy,” and when Cic. wrote the Academica the New Academic dialectic had been without a representative for many years.  Cf.  Introd. p. 21. Libri duo:  cf.  I. 13. Heri for this indication of the contents of the lost Catulus, see Introd. p. 50. Implorans:  “appealing to,” the true meaning being “to appeal to with tears,” see Corss.  I. 361. Philonis:  sc. esse. Scriptum agnoscebat:  i.e. it was an actual work of Ph. Tetrilius:  some MSS. are said to have Tetrinius, and the name Tertinius is found on Inscr.  One good MS. has Tretilius, which may be a mistake for Tertilius, a name formed like Pompilius, Quintilius, Sextilius.  Qy, should Petrilius, a derivative from the word for four, be read? Petrilius and Pompilius would then agree like Petronius and Pomponius, Petreius and Pompeius.  For the formation of these names see Corss.  I. 116. Rogus:  an ill omened and unknown name. Rocus, as Ursinus pointed out, occurs on denarii of the gens Creperia. De Philone ... ab eo ipso:  note the change of prep. “from Philo’s lips,” “from his copy.” De and ex are common in Cic. after audire, while ab is rather rarer.  See M.D.F. I. 39, and for describere ab aliquo cf. a te in Ad Att. XIII. 22, 3.

Sec.12. Dicta Philoni:  for this see Introd. p. 50.  It cannot mean what Goer. makes it mean, “coram Philone.”  I think it probable that Philoni is a marginal explanation foisted on the text.  As to the statements of Catulus the elder, they are made clear by 18. Academicos:  i.e. novos, who are here treated as the true Academics, though Antiochus himself claimed the title. Aristo:  see Introd. p. 11. Aristone:  Diog.  VII. 164 mentions an Aristo of Alexandria, a Peripatetic, who may be the same.  Dio seems unknown. Negat:  see n. on 18. Lenior:  some MSS. levior, as is usual with these two words.  In 11 one of the earliest editions has leviter for leniter.
