Question

　　BetweenA．D． 700 and 1100, northern rovers called Vikings explored most of the known world ． They even crossed the Atlantic and reached the shores of North America． Yet they had no compasses or other modern instruments． How did they find their way?

　　The Vikings stayed near coasts whenever they could． In open seas they navigated by the sun． On cloudy days they used sun stones． Sun stones were probably pieces of a crystal now called cordierite． This substance has the power to filter sunlight． Peering through a sun stone, a sailor could find out where the sun was and thus plot his ship's latitude．

　　Today sky compasses are used to guide some Scandinavian jets across polar regions, where a magnetic compass would be of no use． Though more complex, the sky compass works in the same way as the sun stones used by the Vikings more than a thousand years ago．
