The Port of Qanaʾ, a Junction between the Indian Ocean and the Mediterranean Sea
South Arabian kingdoms based their wealth and power on agriculture and the export of incense and other aromatics so much appreciated in the ancient world. After Aelius Gallus’ campaign against Arabia Felix in 25–24 BC, Roman trade by sea with the region greatly increased compared to the overland caravan routes. This chapter summarizes the political situation in Arabia Felix in those times through the analysis of archaeological, historical, and numismatic evidence and focuses on the harbours and mooring places along the Yemenite and Omani coasts. Italian underwater research at Qanaʾ discovered the ancient anchorage, with ceramics dating between the first and the end of the sixth century AD, with a higher percentage before the fourth century AD. Typological and petrological study suggests the close involvement of the Arabian Peninsula in the web of trade routes that connected the Roman world via the Red Sea with India, and the Persian Gulf.
