into her treasury for every fox, hare, and roe that they had killed in the course of the year. The custom clearly implied that the wild beasts belonged to the goddess, and that she must be compensated for their slaughter. But Diana was not merely a patroness of wild beasts, a mistress of woods and hills, of lonely glades and sounding rivers; conceived as the moon, and especially, it would seem, as the yellow harvest moon, she filled the farmer's grange with goodly fruits, and heard the prayers of women in travail. In her sacred grove at Nemi, as we have seen, she was especially worshipped as a goddess of childbirth, who bestowed offspring on men and women. Thus Diana, like the Greek Artemis, with whom she was constantly identified, may be described as a goddess of nature in general and of fertility in particular. We need not wonder, therefore, that in her sanctuary on the Aventine she was represented by an image copied from the many-breasted idol of the Ephesian Artemis, with all its crowded emblems of exuberant fecundity. Hence too we can understand why an ancient Roman law, attributed to King Tullus Hostilius, prescribed that, when incest had been committed, an expiatory sacrifice should be offered by the pontiffs in the grove of Diana. For we know that the crime of incest is commonly supposed to cause a dearth; hence it would be meet that atonement for the offence should be made to the goddess of fertility. Now on the principle that the goddess of fertility must herself be fertile, it behoved Diana to have a male partner. Her mate, if the testimony of Servius may be trusted, was that Virbius who had his representative, or perhaps rather his embodiment, in the King of the Wood at Nemi. The aim of their union would be to promote the fruitfulness of the earth, of animals, and of mankind; and it might naturally be thought that this object would be more surely attained if the sacred nuptials were celebrated every year, the parts of the divine bride and bridegroom being played either by their images or by living persons. No ancient writer mentions that this was done in the grove at Nemi; but our knowledge of the Arician ritual is so scanty that the want of information on this head can hardly count as a fatal objection to the theory. That theory, in the absence of direct evidence, must necessarily be based on the analogy of similar customs practised elsewhere. Some modern examples of such customs, more or less degenerate, were described in the last chapter. Here we shall consider their ancient counterparts. 2. The Marriage of the Gods
