Glyn Davies, Emeritus Professor at the University of Wales, collaborated with Roy Davies to create this web site. The site traces the development of money through history with a series of essays. The first essay details a chronology of money from the earliest times; other essays discuss the pendulum metatheory of money, the origins of money and banking, warfare and financial history, Celtic coinage, the Vikings, money in North America, the European Monetary Union, government control of the money supply, and Third World debt. Users can also search the site on a particular topic.
