In the first of these two instances, therefore, citizens whom love of their country and its laws could not have retained in Italy, were kept there by the oath forced upon them; and in the second, the tribune Marcus, to keep his oath, laid aside the hatred he bore the father, and overlooked the injury done him by the son, and his own dishonour.

And this from no other cause than the religion which Numa had impressed upon this city.
And it will be plain to any one who carefully studies Roman History, how much religion helped in disciplining the army, in uniting the people, in keeping good men good, and putting bad men to shame; so that had it to be decided to which prince, Romulus or Numa, Rome owed the greater debt, I think the balance must turn in favour of Numa; for when religion is once established you may readily bring in arms; but where you have arms without religion it is not easy afterwards to bring in religion.

We see, too, that while Romulus in order to create a senate, and to establish his other ordinances civil and military, needed no support from Divine authority, this was very necessary to Numa, who feigned to have intercourse with a Nymph by whose advice he was guided in counselling the people.

And this, because desiring to introduce in Rome new and untried institutions, he feared that his own authority might not effect his end.

Nor, indeed, has any attempt ever been made to introduce unusual laws among a people, without resorting to Divine authority, since without such sanction they never would have been accepted.
