Bronze Age cities archaeologists say could be the precursor of Western civilisation are being uncovered in excavations on the Russian steppe.
Twenty of the spiral-shaped settlements, believed to be the original home of the Aryan people, have been identified, and there are about 50 more suspected sites. They all lie buried in a region more than 640km long near Russia’s border with Kazakhstan.
The cities are thought to have been built 3500-4000 years ago, soon after the Great Pyramid in Egypt. They are about the same size as several of the city states of ancient Greece, which started to come into being in Crete at about the same time.
