Two suns over Silla
In 760 two suns appeared and stayed for ten days, says the Samguk yusa, until the monk Wolmyeong sang the 'Tusita Song' and one vanished.

The account
King Gyeongdeok's astrologers advised a Buddhist rite; Wolmyeong composed the hyangga Dosolga, offering flowers to Maitreya. Double suns are a stock omen of rivalry for the throne in East Asian chronicles.
The sceptical view
A parhelion (sun dog) produces a convincing second sun; the ten-day duration is literary.
