“The Vikings were quartering the world; they set out from a base, and with unbelievable courage and ingenuity, they reached as far as Persia by the Volga and the Caspian Sea. Then they returned home with all their loot in these open ships, including coins from Samarkand and even a Chinese Buddha. The sheer technical skill of their journeys was a new achievement, and their spirit did contribute something very important to the Western world, because in the end, it was the spirit of Columbus.”
