Accurate mechanical clocks were developed in ancient China because of a belief in a form of astrology that was based upon the moment of conception rather than the time of birth.Retainers listened outside the royal bedrooms to record the possible times of conception of royal children. This was considered important enough that considerable effort was devoted to developing accurate timing mechanisms.Retainers listened outside the royal bedrooms to record the possible times of conception of royal children.

These clock mechanisms were borrowed in the West and perfected for other purposes. When Jesuits presented such mechanical clocks to the Chinese emperor many centuries later the technology had be forgotten in China and no one knew that the mechanical clock had been invented in China.
