Silver replica of a bowl from Euboea (3000-2800 BC). The original is made of wrought silver and is modelled on Cycladic and eastern patterns. The craftsmanship of the original coupled with the fact that silver is certain to have been mined in the Aegean in the 3rd millennium BC, offer information about the social organization of the period and attest to the development of trade and the progress of technology, both necessary prerequisites for nascent metallurgy to flourish.
