Numerous metallic artefacts, which anciently were deposited in a hoard, came to light per chance on the campus of the Sultan Qaboos University in Al Khawd, Sultanate of Oman. Mostly fashioned from copper, these arrowheads, axes/adzes, bangles, daggers, knives, socketed lance/ spearheads, metal vessels, razors, rings, swords, and tweezers compare well with numerous documented artefact classes from south-eastern Arabia assigned to the Early Iron Age (1200–300 BCE). Discussion of the international trade between ancient Makan, Dilmun, and Mesopotamia during the 3rd millennium BCE dominates the archaeological literature about Arabia archaeology. The Al Khawd hoard and its contemporaries lend weight to the suggestion that 1st millennium BCE Qadē (the name of south-eastern Arabia at that time) was even more important than Bronze Age Makan in terms of the copper trade volume. A reassessment shows the Early Iron Age by no means to be a dark age, but rather an innovative, successful adaptive period characterised by evident population growth.
