Title:
Beijing Ancient Observatory
Explanation:
Did observatories exist before telescopes [ http://antwrp.gsfc.…]? One example that still stands today is the Beijing Ancient Observatory [ http://china-window…] in China. Starting in the 1400s astronomers erected large instruments here to enable them to measure star and planet positions with increasing accuracy. Pre-telescopic observatories [ http://antwrp.gsfc.…] throughout the world date back to before recorded history, providing measurements that helped to determine when to plant crops, how to navigate ships, and when religious ceremonies should occur. The above hand-painted lantern slide [ http://www.emporia.…] was originally taken in 1895.
