Mysterious ancient star chart shows foreign skies

The Kitora Tomb, located near the village of Asuka in Japan's Nara Prefecture, is known for gorgeous, colourful paintings at the four cardinal points of the compass. A black tortoise guards the north of the ancient tumulus, which has been standing since the seventh or eighth century. A red phoenix stands at the south, a white tiger at the west and a blue dragon at the east.

The ceiling of the tomb is decorated differently, with a map of the night sky, charting 68 constellations, with the stars picked out in gold leaf. Three concentric circles are drawn with vermilion, showing the movement of celestial objects, one of which is the sun.

According to Kazuhiko Miyajima, a professor at Doshisha University who studied the chart after the tomb was discovered in 1998, this makes it possibly the oldest astronomical chart of its kind in the world. It has designations for the horizon, equator and ecliptic circles, as well as recognisable patterns of stars.
