In 1961, a seven-ray bronze medallion was discovered during excavations in the Old Bulgarian capital Pliska.The artifact became known as the Pliska Rosette. It has been dated between 7th-9th century A.D. and was mostlikely a tool for astronomical computations.According to researchers, the 7 rays of the Rosette possibly representthe main planets known by the ancients: the Sun, the Moon, Mars, Mercury, Jupiter, Venus and Saturn.The runic symbol "IYI" has been interpreted as "heaven" or "sky" and symblizes the Bulgarian god Tangra, as wellas a being the sign of the acient Bulgarian ruling clan Dulo.
