After the twelfth day remove the hams finally, brush off the salt and hang them for two days in the wind. On the third day wipe them off clean with a sponge and rub them with (olive) oil. Then hang them in smoke for two days, and on the third day rub them with a mixture of (olive) oil and vinegar. Then hang them in the meat house, and neither bats nor worms will touch them.[41] VARRO'S RERUM RUSTICARUM LIBRI TRES BOOK I THE HUSBANDRY OF AGRICULTURE _Introduction: the literary tradition of country life_ I Had I leisure, Fundania, this book would be more worthy of you, but I write as best I may, conscious always of the necessity of haste: for, if, as the saying is, all life is but a bubble, the more fragile is that of an old man, and my eightieth year admonishes me to pack my fardel and prepare for the long journey. You have bought a farm and wish to increase its fertility by good cultivation, and you ask me what I would do with it were it mine. Not only while I am still alive will I try to advise you in this, but I will make my counsel available to you after I am dead. For as it befel the Sibyl to have been of service to mankind not alone while she lived, but even to the uttermost generations of men after her demise (for we are wont after so many years still to have solemn recourse to her books for guidance in interpretation of strange portents), so may not I, while I still live, bequeath my counsel to my nearest and dearest.[42] I will then write three books for you, to which you may have recourse for guidance in all things which must be done in the management of a farm. And since, as men say, the gods aid those who propitiate them, I will begin my book by invoking divine approval, not like Homer and Ennius, from the Muses, nor indeed from the twelve great gods of the city whose golden images stand in the forum, six male and as many female, but from a solemn council of those twelve divinities who are the tutelaries of husbandmen. * * * * * First: I call upon Father Jupiter and Mother Earth, who fecundate all the processes of agriculture in the air and in the soil, and hence are called the great parents. _Second_: I invoke the Sun and the Moon by whom the seasons for sowing and reaping are measured. _Third_: I invoke Ceres and Bacchus because the fruits they mature are most necessary to life, and by their aid the land yields food and drink. _Fourth_: I invoke Robigus and Flora by whose influence the blight is kept from crop and tree, and in due season they bear fruit (for which reason is the annual festival of the _robigalia_ celebrated in honour of Robigus, and that of the _floralia_ in honour of Flora).[43] _Next_: I supplicate Minerva, who protects the olive; and Venus, goddess of the garden, wherefore is she worshipped at the rural wine festivals.
