The language and treatment, such as they are (and they do not sink to the level of the histories of the African and Spanish wars), are of this, and not of a later age, and quite consonant with the good- natured contempt which Nepos met at the hands of later Roman critics. The chief interest of the work is perhaps the clearness with which it enforces the truth we are too apt to forget, that the great writers were in their own age, as now, unique, and that there is no such thing as a widely diffused level of high literary excellence. As remote from literature in the higher sense were the innumerable writings of the Ciceronian age on science, art, antiquities, grammar, rhetoric, and a hundred miscellaneous subjects, which are, for the most part, known only from notices in the writings of later commentators and encyclopedists. Foremost among the voluminous authors of this class was the celebrated antiquarian, Marcus Terentius Varro, whose long and laborious life, reaching from two years after the death of the elder Cato till the final establishment of the Empire, covers and overlaps the entire Ciceronian age. Of the six or seven hundred volumes which issued from his pen, and which formed an inexhaustible quarry for his successors, nearly all are lost. The most important of them were the one hundred and fifty books of _Saturae Menippeae_, miscellanies in prose and verse in the manner which had been originated by Menippus of Gadara, the master of the poet Meleager, and which had at once obtained an enormous popularity throughout the whole of the Greek-speaking world; the forty- one books of _Antiquitates Rerum Humanarum et Divinarum_, the standard work on the religious and secular antiquities of Rome down to the time of Augustine; the fifteen books of _Imagines_, biographical sketches, with portraits, of celebrated Greeks and Romans, the first certain instance in history of the publication of an illustrated book; the twenty-five books _De Lingua Latina_, of which six are extant in an imperfect condition; and the treatise _De Re Rustica_, which we possess in an almost complete state. This last work was written by him at the age of eighty. It is in the form of a dialogue, and is not without descriptive and dramatic power. The tediousness which characterised all Varro's writing is less felt where the subject is one of which he had a thorough practical knowledge, and which gave ample scope for the vein of rough but not ungenial humour which he inherited from Cato.
