that it was comprised in two books, the first bearing the name of Catulus, the second that of Lucullus. A copy was sent to Atticus; and, soon after it reached him, two new Introductions were composed, the one in praise of Catulus, the other in praise of Lucullus. Scarcely had this been done, when Cicero, from a conviction that Catulus, Lucullus, and Hortensius, although men of highly cultivated minds, and well acquainted with general literature, were known to have been little conversant with the subtle arguments of abstruse philosophy, determined to withdraw them altogether, and accordingly substituted Cato and Brutus in their place. Immediately after this change had been introduced, he received a communication from Atticus, representing that Varro was much offended by being passed over in the discussion of topics in which he was so deeply versed. Thereupon Cicero, catching eagerly at the idea thus suggested, resolved to recast the whole piece, and quickly produced, under the old title, a new and highly improved edition, divided into four books instead of two, dedicating the whole to Varro, to whom was assigned the task of defending the tenets of Antiochus; while Cicero himself undertook to support the views of Philo, Atticus also taking a share in the conversation.
“But, although these alterations had been effected with extreme rapidity, the copy originally sent to Atticus had in the meantime been repeatedly transcribed; hence both editions passed into circulation, and a part of each has been preserved. One section, containing twelve chapters, is a short fragment of the second or Varronian edition. The other, containing forty-nine chapters, is the entire second book of the first edition; to which is prefixed the new introduction, together with the proper title of Lucullus. The scene of the Catulus was the villa of that statesman, at Cumæ; while the Lucullus is supposed to have been held at the mansion of Hortensius, near Bauli.
“The object proposed was to give an account of the rise and progress of the Academic Philosophy, to point out the various modifications introduced by successive professors, and to demonstrate the superiority of the principles of the New Academy, as taught by Philo, over those of the old, as advocated by Antiochus.”
