”KYOTO–Rulers of ancient Japan may have used a “magic mirror” to conjure up images of mountain wizards and divine beasts for sun-worshipping rituals.
The Kyoto National Museum said Jan. 29 patterns engraved on the back of a type of bronze mirror associated with ancient queen Himiko are projected on a wall when sunlight reflects off the front.”
