But they regard these as poetic fancies, and assert that the father of Picus was Sterces rather, and relate that, being a most skilful husbandman, he discovered that the fields could be fertilized by the dung of animals, which is called stercus from his name. Some say he was called Stercutius. But for whatever reason they chose to call him Saturn, it is yet certain they made this Sterces or Stercutius a god for his merit in agriculture; and they likewise received into the number of these gods Picus his son, whom they affirm to have been a famous augur and warrior. Picus begot Faunus, the second king of Laurentum; and he too is, or was, a god with them. These divine honours they gave to dead men before the Trojan war.
