6. From Switzerland Austria and Germany, the Celts spread across the rest of central Europe
Hallstatt Celtic culture, with its iron weapons, and horse-drawn chariots quickly began to dominate Europe. Celtic influences started to expand out of Germany and Austria to stretch across Europe. By the late first century BC, the Roman geographer Strabo was able to report how “Celtica” spread “as far as the river Rhone. Its northern side is washed by the whole length of the British channel, for the whole length of the island of Britain is parallel and lies over against the whole of Celtica…..its eastern side is bound by the river Rhone …..on the southern side it is bound in part by the alps…and in part by the Mediterranean….in which areas are the notable cities of Marseilles and Narbonne.”
