7. But why do I speak of these trifles? What man is there who is ignorant that in the Capitol of the imperial people is the sepulchre of Tolus Vulcentanus? Who is there, I say, who does not know that from beneath its foundations there was rolled a man&#8217;s head, buried for no very long time before, either by itself without the other parts of the body,&#8212;for some relate this,&#8212;or with all its members? Now, if you require this to be made clear by the testimonies of authors, Sammonicus, Granius, Valerianus, and Fabius will declare to you whose son Aulus was, of what race and nation, how he was bereft of life and light by the slave of his brother, of what crime he was guilty against his fellow-citizens, that he was denied burial in his father land. You will learn also&#8212;although they pretend to be unwilling to make this public&#8212;what was done with his head when cut off, or in what place it was shut up, and the whole affair carefully concealed, in order that the omen which the gods had attested might stand without interruption, unalterable, and sure. Now, while it was proper that this story should be suppressed, and concealed, and forgotten in the lapse of time, the composition of the name published it, and, by a testimony which could not be got rid of, caused it to remain in men&#8217;s minds, together with its causes, so long as it endured itself; and the state which is greatest of all, and worships all deities, did not blush in giving a name to the temple, to name it from the head of Olus Capitolium rather than from the name of Jupiter.
