Soon certain energetic merchants discovered that the goods which they had always imported from afar could be made at home.They turned part of their homes into a workshop.They ceased to be merchants and became manufacturers.They sold their products not only to the lord of the castle and to the abbot in his monastery, but they exported them to nearby towns.The lord and the abbot paid them with products of their farms, eggs and wines, and with honey, which in those early days was used as sugar.But the citizens of distant towns were obliged to pay in cash and the manufacturer and the merchant began to own little pieces of gold,which entirely changed their position in the society of the early Middle Ages.It is difficult for you to imagine a world without money.In a modern city one cannot possible live without money.All day long you carry a pocket full of small discs of metal to "pay your way."You need a nickel for the street-car, a dollar for a dinner, three cents for an evening paper.But many people of the early Middle Ages never saw a piece of coined money from the time they were born to the day of their death.The gold and silver of Greece and Rome lay buried beneath the ruins of their cities.The world of the migrations, which had succeeded the Empire, was an agricultural world.Every farmer raised enough grain and enough sheep and enough cows for his own use.
