A post-chaise is a fast carriage for traveling post built in the 18th and early 19th centuries. It usually had a closed body on four wheels, sat two to four persons, and was drawn by two or four horses.
A postilion rode on the near-side (left, nearest the roadside) horse of a pair or of one of the pairs attached to the post-chaise[1] leaving passengers a clear view of the road ahead.
