With the use of a great deal of money and little sense the Dutch nobleman Philips Doublet had a succession of improved coaches built. When his brother-in-law Christiaan Huygens settled in Paris in the royal service, Doublet wished to be kept informed of the latest fashion in carriages. Huygens himself also became enthusiastic and started designing his own coaches. Initially he stuck obstinately to a two-wheeled gig, but was finally forced to admit that only a four-wheeled carriage was really comfortable. His carriage did, though, turn out better than others. Huygens' coach was so good that while he was away a colleague ventured to break in and borrow it. Huygens was furious and complained personally to the Prime Minister.
