A research team has discovered what may be the oldest astrologer's board, engraved with zodiac signs and used to determine a person's horoscope.

Dating back more than 2,000 years, the board was discovered in Croatia, in a cave overlooking the Adriatic Sea. The surviving portion of the board consists of 30 ivory fragments engraved with signs of the zodiac. Researchers spent years digging them up and putting them back together. Inscribed in a Greco-Roman style, they include images of Cancer, Gemini and Pisces. 

The board fragments were discovered next to a phallic-shaped stalagmite amid thousands of pieces of ancient Hellenistic (Greek style) drinking vessels.
