The Astronomers from The Story of the Emperor of China Series tapestry shows some important instruments used for navigation during the Age of Exploration and the Scientific Revolution. Ideas were shared and built upon as exchanges between cultures became more common.
The following list of dates notes when important astronomical and navigational instruments were developed. Place the dates and the information on the timeline worksheet provided. The facts are grouped by their place of origin: China, Europe, and Arabia. Use a different color pen or pencil for each place, as you fill in your timeline. Write all of the information from China in one color, Europe in one color, and Arabia in one color. Include drawings and symbols for the objects that are underlined. Be neat and be creative. 
China:
250 A.D.	Chinese develop the water-powered astronomical globe.
1044 A.D.	The use of a compass, or a “south-pointing fish,” is first mentioned.

Europe:

1668 A.D.	Isaac Newton of England develops the first reflecting telescope.

Arabia:
800-900 A.D.	Islamic astronomers develop the astrolabe to determine the time of day (and direction to Mecca). They can now precisely measure the positions of stars and planets.
