The name Didymé for the ancient city of Cádiz

In ancient times, Cádiz was known as Didymé. According to authors such as Pomponio Mela and Plinio el Viejo, the city was considered an island, a fact that still holds true today, though it may not be immediately apparent. Cádiz had two urban centers, one on the islets and another on the mainland.

The name Didymé (in ancient Greek, didymé) means 'twin', referring to these two urban centers. While the city became a major hub of Roman commerce, it remained the home of the gaditanos, who were expert navigators and shipbuilders.
