The Sumerian had a very thorough understanding of metal, and the socketed axes, for example, which are normal in the graves, are far in advance of anything produced by Egyptian smiths, who for the hafting of their weapons did not get beyond the primitive system of tang and rivet until late in history; whether the metal be gold, silver, electrum, or copper, the casting is without flaw and the design is so admirably suited to its purpose that spear-blade, dagger, and axe become things of beauty.
