Квинт Цецилий Метелл Пий
The "Regio III" within the city of Rome was named "Isis et Serapis" because it contained a temple dedicated to the two Egyptian deities. The structure, originally dedicated to Isis alone, was built by Quintus Caecilius Metellus Pius in the first half of the 1st century BCE to celebrate his father's victory over Jugurtha.
