Of the gods peculiar to the Romans, and their sacred rites
When their city was occupied by the Gauls, and the Romans, who were besieged in the Capitol, had made military engines from the hair of the women, they dedicated a temple to the Bald Venus. They do not therefore understand how vain are their religions, even from this very fact, that they jeer at them by these follies. They had perhaps learned from the Lacedæmonians to invent for themselves gods from events. For when they were besieging the Messenians, and they (the Messenians) had gone out secretly, escaping the notice of the besiegers, and had hastened to plunder Lacedæmon, they were routed and put to flight by the Spartan women. But the Lacedæmonians, having learned the stratagem of the enemy, followed. The women in arms went out to a distance to meet them; and when they saw that their husbands were preparing themselves for battle, supposing them to be Messenians, they laid bare their persons. But the men, recognising their wives, and excited to passion by the sight, rushed to promiscuous intercourse, for there was not time for discrimination. In like manner, the youths who had on a former occasion been sent by the same people, having intercourse with the virgins, from whom the Partheniæ were born, in memory of this deed erected a temple and statue to armed Venus. And although this originated in a shameful cause, yet it seems better to have consecrated Venus as armed than bald. At the same time an altar was erected also to Jupiter Pistor (the baker), because he had admonished them in a dream to make all the grain which they had into bread, and throw it into the camp of the enemy; and when this was done, the siege was ended, since the Gauls despaired of being able to reduce the Romans by want.
What a derision of religious rites is this! I were a defender of these, what could I complain of so greatly as that the name of gods had come into such contempt as to be mocked by the most disgraceful names? Who would not laugh at the goddess Fornax, or rather that learned men should be occupied with celebrating the Fornacalia? Who can refrain from laughter on hearing of the goddess Muta? They say that she is the goddess from whom the Lares were born, and they call her Lara, or Larunda. What advantage can she, who is unable to speak, afford to a worshipper? Caca also is worshipped, who informed Hercules of the theft of his oxen, having obtained immortality through the betrayal of her brother; and Cunina, who protects infants in the cradle, and keeps off witchcraft; and Stercutus, who first introduced the method of manuring the land; and Tutinus, before whom brides sit, as an introduction to the marriage rites; and a thousand other fictions, so that they who regarded these as objects of worship may be said to be more foolish than the Egyptians, who worship certain monstrous and ridiculous images. These however, have some delineation of form. What shall I say of those who worship a rude and shapeless stone under the name of Terminus? This is he whom Saturnus is said to have swallowed in the place of Jupiter; nor is the honour paid to him undeservedly. For when Tarquinius wished to build the Capitol, and there were the chapels of many gods on that spot, he consulted them by augury whether they would give way to Jupiter; and when the rest gave way, Terminus alone remained. From which circumstance the poet speaks of the immoveable stone of the Capitol. Now from this very fact how great is Jupiter found to be, to whom a stone did not give way, with this confidence, perhaps, because it had rescued him from the jaws of his father! Therefore, when the Capitol was built, an aperture was left in the roof above Terminus himself, that, since he had not given way, he might enjoy the free heaven; but they did not themselves enjoy this, who imagined that a stone enjoyed it. And therefore they make public supplications to him, as to the god who is the guardian of boundaries; and he is not only a stone, but sometimes also a stock. What shall I say of those who worship such objects, unless— that they above all others are stones and stocks?
