Numa

The buckler came, he said, for the salvation of the city, and must be carefully preserved by making eleven others of like fashion, size, and shape, in order that the resemblance between them might make it difficult for a thief to distinguish the one that fell from heaven. He said further that the spot where it fell, and the adjacent meadows, where the Muses usually had converse with him, must be consecrated to them; and that the spring which watered the spot should be declared holy water for the use of the Vestal virgins, who should daily sprinkle and purify their temple with it.

Moreover, they say that the truth of all this was attested by the immediate cessation of the pestilence. When Numa showed the buckler to the artificers and bade them do their best to make others like it, they all declined, except Veturius Mamurius, a most excellent workman, who was so happy in his imitation of it, and made all the eleven so exactly like it, that not even Numa himself could distinguish them. For the watch and care of these bucklers, then, he appointed the priesthood of the Salii.
