We have thus to face two formidable facts: (1) that the period covered by my earlier lectures must in honesty be called prehistoric; and (2) that when the Romans themselves began to write about it they did so under the overwhelming influence of Greek culture. With few exceptions, all that we can learn of the early Roman religion from Roman or Greek writers comes to us, not in a pure Roman form, clearly conceived as all things truly Roman were, but seen dimly through the mist of the Hellenistic age. The Roman gods, for example, are made the sport of fancy and the subject of Hellenistic love-stories, by Greek poets and their Roman imitators,[13] or are more seriously treated by Graeco-Roman philosophy after a fashion which would have been absolutely incomprehensible to the primitive men in whose minds they first had their being. The process of disentangling the Roman element from the Greek in the literary evidence is one which can never be satisfactorily accomplished; and on the whole it is better, with Wissowa and Marquardt, to hold fast by the facts of the cult, where the distinction between the two is usually obvious, than to flounder about in a slough of what I can only call pseudo-evidence. If all that English people knew about their Anglo-Saxon forefathers were derived from Norman-French chroniclers, how much should we really know about government or religion in the centuries before the Conquest! And yet this comparison gives but a faint idea of the treacherous nature of the literary evidence I am speaking of. It is true indeed that in the last age of the Republic a few Romans began to take something like a scientific interest in their own religious antiquities; and to Varro, by far the most learned of these, and to Verrius Flaccus, who succeeded him in the Augustan age, we owe directly or indirectly almost all the solid facts on which our knowledge of the Roman worship rests. But their works have come down to us in a most imperfect and fragmentary state, and what we have of them we owe mainly to the erudition of later grammarians and commentators, and the learning of the early Christian fathers, who drew upon them freely for illustrations of the absurdities of paganism. And it must be added that when Varro himself deals with the Roman gods and the old ideas about them, he is by no means free from the inevitable influence of Greek thought.
