Livy: The Practice of Deditio (Book 1.38)
Collatia and all the territory on this side of it was taken from the Sabines; Egerius, the king's nephew, was left to hold it. I understand that the procedure on the surrender of Collatia was as follows: The king asked, "Have you been sent as envoys and commissioners by the people of Collatia to make the surrender of yourselves and the people of Collatia?" "We have." "And is the people of Collatia an independent people?" "It is." "Do you surrender into my power and that of the People of Rome yourselves, and the people of Collatia, your city, lands, water, boundaries, temples, sacred vessels, all things divine and human?" "We do surrender them." "Then I accept them."
