• In Ancient China, they believed that
solar eclipses were caused by a giant

and arrows fired into the air. After the
few minutes, the loud noises and
weapons scared off the dragon, and
the sun returned.

that the sun and moon were gods,
and during a solar eclipse they left
their places in the sky to see how
things were doing on Earth.
