protestations of friendship, Varro appears to have maintained a somewhat cool or distant attitude. At last, however, this reserve was broken through. In 47 B.C. he seems to have promised Cicero to dedicate a work to him, which by its magnitude and interest required careful labour. In the letter prefixed to the posterior _Academica_, 45 B.C., Cicero evinces much impatience at having been kept two years waiting for his promised boon, and inscribes his own treatise with Varro's name as a polite reminder which he hopes his friend will not think immodest. In the opening chapters Cicero extols Varro's learning with that warmth of heart and total absence of jealousy which form so pleasing a trait in his character. Their diffuseness amusingly contrasts with Varro's brevity in his dedication. When it appeared, there occurred not a word of compliment, nothing beyond the bare announcement _In his ad te scribam_. [33] Truly Varro was no "mutual admirationist." C. O. Müller, who has edited this treatise with great care, is of opinion that it was never completely finished. He argues partly from the words _politius a me limantur_, put into Varro's mouth by Cicero, partly from the civil troubles and the perils into which Varro's life was placed, partly from the loose unpolished character of the work, that it represents a first draught intended, but not ready for, publication. For example, the same thing is treated more than once; _Jubar_ is twice illustrated by the same quotation, [34] _Canis_ is twice derived from _canere_; [35] _merces_ is differently explained in two places; [36] _Lympha_ is derived both from _lapsus aquae_, and from _Nympha_; [37] _valicinari_ from _vesanus_ and _versibus viendis_. [38] Again marginal additions or corrections, which have been the means of destroying the syntactical connection, seemed to have been placed in the text by the author. [39] Other insertions of a more important character though they illustrate the point, yet break the thread of thought; and in one book, the seventh, the want of order is so apparent that its finished character could hardly be maintained. These facts lead him to conclude that the book was published without his knowledge, and perhaps against his will, by those who pillaged his library. It is obvious that this is a theory which can neither be proved nor disproved. It is an ingenious excuse for Varro's negligence in not putting his excellent materials together with more care. The plan of the work is as follows:-- Book I.--On the origin of the Latin language.
