Bring the hind part of one Egyptian chariot opposite to the hind part of another, lash the two chariots together, remove the tongue of one of the chariots and you have made a chariot of four wheels or a _coach_. The form of the most ancient of four-wheeled carriages leads to the belief that the coach was first made by joining together two two-wheeled chariots in the way just described. The ancient Egyptians had their four-wheeled chariots but only their gods and their kings had the privilege of riding in them. For centuries none but the great and the powerful rode in coaches. The Roman chariot (Fig. 14), bad imitations of which we see nowadays in circus processions, was used only in the splendid triumphal processions which entered Rome after a great victory. In the Middle Ages we get a glimpse of a four-wheeled carriage now and then, but usually the king or a queen is lounging in it (Fig. 15). The coach could not be generally used in Europe in medieval times because the roads were so bad. The excellent roads made by the Romans had not been kept in good condition. Traveling had to be done either on horseback or in the two-wheeled carriage. In 1550 there were but three coaches in Paris and in London there was but one. In 1564, however, we find Queen Elizabeth riding in a coach (Fig. 16) on her way to see her lover, Lord Leicester. Insert more spokes and lighter ones in the wheels of this coach of the queen's, put on rubber tires and mount the body on elliptical springs[17] and we will have the coach of to-day.
