Origin of the tin ingots from Uluburun

It largely remains an open question of how much Alexander knew about the lands he set out to conquer. The answer or answers keep amazing me. 

Imagine that Alexander was familiar with the trade routes of the precious minerals like copper and tin that existed nearly one thousand years before he was born. Today, we would say it is rather obvious but is it? 

Merchants were always very innovative and perseverant in exploring and finding new markets for their goods to be sold at the highest prices. The shipwreck of Uluburun was a true eye-opener, exposing the variety of ware from distant countries that were traded mainly around the Mediterranean. 

In my earlier blog, The flooded remains of Kekova Island and Uluburun, I mentioned that the ship was on its way from Egypt to the Black Sea when it sunk off the coast of Uluburun in modern Turkey. It carried, among others, 10 tons of copper ingots from Cyprus and an unspecified number of tin ingots from Persia. 

It was lengthy to bring the cargo from the Uluburun ship to the surface, as it took 22,430 dives. The precious finds are now safely exhibited inside the Museum of Bodrum Castle, surrounded by lively reconstructions of the ship’s haul. I somehow missed spotting the tin ingots as I focused on the copper and glass ingots instead. 

It is common knowledge that copper and tin are needed to make bronze. Since the second millennium BC, bronze has been in high demand to create tools and objects of prestige, but most of all for weapons. It is noteworthy that the Uluburun ship held enough metal to supply swords to 5,000 soldiers! 

A recent study published in The Past established that two-thirds of the 105 tin ingots originated from the Taurus Mountains in Turkey, and one-third was traced back to Tajikistan and Uzbekistan. These two countries are roughly 3000 kilometers east of Uluburun!

During the Bronze Age, the mines of Central Asia were local operations led by small mobile villagers. Tin from the Musiston mine traveled over rugged and rough terrain to Haifa - a distance of more than 3,000 km – before it was shipped across the Mediterranean.
