 The writing utilizes foundation legends which epitomize the way in which narratives on the origins of cities were formulated.Ranzano’s investigations with regards to attempting to learn of the origins of Palermo (circa quista origini di la mia patria), place him in the context of the prevailing quest in the Renaissance era for sources (ad fontes) and his quest would lead him to an inscription which he would assume to be "Chaldean" characters which were inscribed on a tower which stood above the Porta Patitelli in Palermo.The inscription would later be discovered to be a forgery therefore rendering Ranzano’s deduction that the city of Palermo originated from the Chaldeans as erroneous.
