3. Imagines in 15 books. This consisted of 700 biographies of famous Greeks and Romans, each biography being accompanied by a portrait of the subject and an explanatory metrical elogium. This was probably the first Latin illustrated book, but Cratenas, the medical attendant of Mithridates VI. (12o-63 B.c.) had shown the way by an illustrated book on plants. The number of biographies, 700, is explained by Varro's curious affection for the number 7 (hebdomas),: cf. Aul. Gell., iii. ro. "M. Varro in the first of the books entitled Hebdomades or De Imaginibus says that the virtues and powers of the number 7, which the Greeks call gi3So,ults are many and various": cf. M. Varro in primo de Imaginibus, titer (Homer or Hesiod) prior sit natus, parum constare dicit; ibid. 6. M. Varro in the first book, de Imaginibus, placed beside the portrait of Homer this epigram : Capella Homeri candida haec tumulum in dicat Quod hac Ietae mortuo faciunt sacra (This shining she goat indicates the tomb of Homer, because it is with a she-goat that the Ietae sacrifice to the dead).
4. On literature and the history of literature he wrote a series of treatises, e.g., De poematis, De compositione saturarum, De Poetis (Aul. Gell., i. 24.3; xvii. 21, 43 and 45), De originibus scaenicis, De comoediis Plautinis (Aul. Gell., iii. 3. 9 seq.), Quaes tionum Plautinarum libri V. In this connection it is to be noted that Varro established the canon of the genuine plays of Plautus, the 21 so-called Fabulae Varronianae, i.e., the 21 plays now extant (the Vidularia only partially).
S. Antiquitatum rerun humanarum et divinarum libri XLI. Of this work the first 25 books dealt with res humane, the second part in 16 books, dedicated to Caesar, dealt with the gods. For the first part, cf. Aul. Gell., i.16, i.25, iii.2, v.4, xi. I, xiii.I2, xiii.I3, xiii.I7, xvii.3; for the second part cf. Aul. Gell., i.18, iii.16, x.15, xv.3o, xviii.i 2. Other works in this sphere written by Varro were De gente populi Romani libri IV, De vita populi Romani, De familiis Troianis, Tribuum liber, Rerum urbancrum libri III, Aetia (so called after the Airca of Callimachus).
6. Historical works: De Pompeio libri III., Annalium libri De sua vita, Legationum libri III.
books were dedicated to P. Septimius, the rest to Cicero; cf. Aul. Gell., ii.25, vi.i 1, X.2I, xvi.8. Bks. 5–lo are extant in a somewhat mutilated condition. The work was divided into three parts, the first dealing with the etymology of Latin words, the second with inflexion, the third with syntax. Other works in this sphere by Varro were De sermone Latino ad Marcellum libri V. (cf. Aul. Gell., xii.6, xii.io, xvi.I2, xviii.I2); De similitudine verborum; De utilitate sermonis ; rEpl De anti quitate litterarum; De origine linguae Latinae.
II. Epistolicae Quaestiones (Aul. Gell., vi.io, xiv.7, xiv.8) dealing with a variety of subjects.
I2. Rerum rusticarum libri III., written when Varro was in his Both year. (Cf. the opening words, "If I had leisure, Fundania, I would have written for you more conveniently what I will now set forth as best I can, considering that I must make haste, since, as the saying goes, if man is a bubble, still more so is an old man. My Both year warns me that I must collect my baggage before I depart from life.") This work (for which cf. Aul. Gell, ii. 2o) is extant practically entire.
