Archaeologists have made a groundbreaking discovery off the Italian coast near Naples. A 2,000-year-old temple built by Arabian immigrants from the Nabataean culture has been found submerged in the sea. The temple's elaborate architecture and inscriptions suggest it was dedicated to the main god of the Nabataeans, Dushara. The find provides insight into the cultural exchange between the ancient civilizations.
