The Sarmatians  were an Iranian people during classical antiquity, flourishing from about the 5th century BC to the 4th century AD. They spoke Scythian, an Indo-European language from the Eastern Iranian family. Originating in Central Asia, the Sarmatians started their westward migration around the 6th century bc, coming to dominate the closely related Scythians by the 2nd century bc. The Sarmatians differed from the Scythians in their veneration of the god of fire rather than god of nature, and their women's prominent role in warfare, which possibly served as the inspiration for the Amazons. At their greatest reported extent, around 1st century AD, these tribes ranged from the Vistula River to the mouth of the Danube and eastward to the Volga, bordering the shores of the Black and Caspian seas as well as the Caucasus to the south. Their territory, which was known as Sarmatia to Greco-Roman ethnographers, corresponded to the western part of greater Scythia . According to authors Arrowsmith, Fellowes and Graves Hansard in their book A Grammar of Ancient Geography published in 1832, Sarmatia had two parts, Sarmatia Europea and Sarmatia Asiatica covering a combined area of 503,000 sq mi or 1,302,764 km2.

How many years did it take from the beginning of the Sarmatians' migration until their greatest reported extent?
A: 700

In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on the Tigris and Euphrates rivers and a canal system for irrigation. Ploughs appear in pictographs around 3,000 BC; seed-ploughs around 2,300 BC. Farmers grew wheat, barley, vegetables such as lentils and onions, and fruits including dates, grapes, and figs. Ancient Egyptian agriculture relied on the  Nile River and its seasonal flooding. Farming started in the predynastic period at the end of the Paleolithic, after 10,000 BC. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. Agriculture in India, wheat, barley, and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle, sheep and goats were domesticated in Mehrgarh by 8,000–6,000 BC. Cotton was cultivated by the 5th-4th millennium BC. There is archeological evidence of an animal-drawn plough from 2,500 BC in the Indus Valley Civilization. Agriculture in China, from the 5th century BC there was a nationwide granary system and widespread sericulture. Water-powered grain mills were in use by  the 1st century BC, followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron ploughshares and mouldboards. These slowly spread westwards across Eurasia. Asian rice was domesticated 8,200–13,500 years ago in China, with a single genetic origin from the wild rice Oryza rufipogon. Agriculture in ancient Greece and Roman agriculture, the major cereals were wheat, emmer, and barley, alongside vegetables including peas, beans, and olives. Sheep and goats were kept mainly for dairy products.
