There is no evidence in the Bucolics that Virgil ever had any practical knowledge of agriculture before he undertook to write the Georgics. His father was, it is true, a farmer, but apparently in a small way and unsuccessful, for he had to eke out a frugal livelihood by keeping bees and serving as the hireling deputy of a viator or constable. This type of farmer persists and may be recognized in any rural community: but the agricultural colleges do not enlist such men into their faculties. So it is possible that Virgil owed little agricultural knowledge to his father's precepts or example. Virgil perhaps had tended his father's flock, as he pictures himself doing under the guise of Tityrus; certainly he spent many hours of youth "patulae recubans sub tegmine fagi" steeping his Celtic soul with the beauty and the melancholy poetry of the Lombard landscape: and so he came to know and to love bird and flower and the external aspects of
wheat and woodland tilth and vineyard, hive and horse and herd,
but it does not appear that he ever followed the plough, or, what is more important, ever laid off a ploughgate. As a poet of nature no one was ever better equipped (the highest testimony is that of Tennyson), but when it came to writing poetry around the art of farm management it was necessary for him to turn to books for his facts. He acknowledges (Geo. I, 176) his obligation only to veterum praecepta without naming them, but as M. Gaston Boissier says he was evidently referring to Varro "le plus moderne de tous les anciens."[7] Virgil evidently regarded Varro's treatise as a solid foundation for his poem and he used it freely, just as he drew on Hesiod for literary inspiration, on Lucretius for imaginative philosophy, and on Mago and Cato and the two Sasernas for local colour.
Virgil probably had also the advantage of personal contact with Varro during the seven years he was composing and polishing the Georgics. He spent them largely at Naples (Geo. IV, 563) and Varro was then established in retirement at Cumae: thus they were neighbours, and, although they belonged to different political parties, the young poet must have known and visited the old polymath; there was every reason for him to have taken advantage of the opportunity. Whatever justification there may be for this conjecture, the fact remains that Varro is in the background every where throughout the Georgics, as the "deadly parallel" in the appended note will indicate. This is perhaps the most interesting thing about Varro's treatise: instructive and entertaining as it is to the farmer, in the large sense of the effect of literature on mankind, Virgil gave it wings—the useful cart horse became Pegasus.
As a consequence of the chorus of praise of the Georgics, there have been those, in all ages, who have sneered at Virgil's farming. The first such advocatus diaboli was Seneca, who, writing to Lucilius (Ep. 86) from the farm house of Scipio Africanus, fell foul of the advice (Geo, I, 216) to plant both beans and millet in the spring, saying that he had just seen at the end of June beans gathered and millet sowed on the same day: from which he generalized that Virgil disregarded the truth to turn a graceful verse, and sought rather to delight his reader than to instruct the husbandman. This kind of cheap criticism does not increase our respect for Nero's philosophic minister.[8] Whatever may have been Virgil's mistakes, every farmer of sentiment should thank God that one of the greatest poems in any language contains as much as it does of a sound tradition of the practical side of his art, and here is where Varro is entitled to the appreciation which is always due the schoolmaster of a genius.
NOTE ON THE OBLIGATION OF VIRGIL TO VARRO
At the beginning of the first Georgic (1-5) Virgil lays out the scope of the poem as dealing with three subjects, agriculture, the care of live stock and the husbandry of bees. This was Varro's plan (R.R. I, I, 2, and I, 2 passim) except that under the third head Varro included, with bees, all the other kinds of stock which were usually kept at a Roman steading. Varro asserts that his was the first scientific classification of the subject ever made. Virgil (G. I, 5-13) begins too with the invocation of the Sun and the Moon and certain rural deities, as did Varro (R.R. I, I, 4). The passages should be compared for, as M. Gaston Boissier has pointed out, the difference in the point of view of the two men is here illustrated by the fact that Varro appeals to purely Roman deities, while Virgil invokes the literary gods of Greece. Following the Georgics through, one who has studied Varro will note other passages for which a suggestion may be found in Varro, usually in facts, but some times in thought and even in words, viz: Before beginning his agricultural operations a farmer should study the character of the country (G. I, 50: R.R. I, 6), the prevailing winds and the climate (G. I, 51: R.R. I, 2, 3), the farming practice of the neighbourhood (G. I, 52: R.R. I, 18, 7), "this land is fit for corn, that for vines, and the other for trees," (G. I, 54: R.R. I, 6, 5). He should practise fallow and rotation (G. I, 71: R.R. I, 44, 2), and compensate the land by planting legumes (G. I, 74: R.R. I, 23); he should irrigate his meadows in summer (G. I, 104: R.R. I, 31, 5), and drain off surface water in winter (G. I, 113: R.R. I, 36). Man has progressed from a primitive state, when he subsisted on nuts and berries, to the domestication of animals and to agriculture (G. I, 121-159: R.R. II, 1, 3). The threshing floor must be protected from pests (G. I, 178: R.R. I, 51). Seed should be carefully selected (G. I, 197: R.R. 40, 2); the time for sowing grain is the autumn (G. I, 219: R.R. I, 34). "Everlasting night" prevails in the Arctic regions (G. I, 247: R.R. I, 2, 5); the importance to the farmer of the four seasons (G.I. 258; R.R. I, 27) and the influence of the Moon (G.I. 276: R.R. I, 37).
The several methods of propagating plants described (G. II, 9-34: R.R. I, 39), but here Varro follows Theophrastus (H.P. II, 1); trees grow slowly from seed (G. II, 57; R.R. I, 41, 4); olives are propagated from truncheons (G. II, 63; R.R. I, 41, 6). "The praise of Italy" (G. II, 136-176: R.R. I, 2, 6), where trees bear twice a year (G. II, 150: R.R. I, 7, 6). Certain plants affect certain soils (G. II, 177: R.R. I, 9). A physical experiment (G. II, 230; R.R. I, 7); the advantage of the quincunx in planting (G. II, 286: R.R. I, 7). Fence the vineyard to keep out live stock (G. II, 371: R.R. I, 14); the goat a proper sacrifice to Bacchus (G. II, 380: R.R. I, 2, 19). Be the first to put your vine props under cover (G. II, 409: R.R. I, 8, 6).
The points of cattle (G. III, 50: R.R. II, 5, 7); their breeding age (G. III, 61: R.R. II, 5, 13); segregate the bulls before the breeding season (G. III, 212: R.R. II, 5, 12). Recruit your herd with fresh blood (G. III, 69: R.R. II, 5, 17). How to break young oxen (G. III, 163: R.R. I, 20).
Of breeding live stock, the males should be fat, the females lean (G.
III, 123-129: R.R. II, 5, 12).
