Explanation: The example illustrates how the Jus Quiritium was the original law of the Romans. It was based on the customs and traditions of the people and was enforced by the magistrates. As Rome grew and evolved, new laws were developed, such as the jus praetorium and the jus gentium, but the Jus Quiritium remained an important part of Roman law.
