This symbol, reminiscent of a yin-yang, is a Mayan emblem of unknown meaning.
In the nineteen-fifties, it was associated in New Age circles with the Mayan God-name Hunab Ku, although there remains little evidence to support the connection.
While the symbol is Mayan in origin, it is most often used in a New Age context, where represents the solar calendar, balanced forces, and universal harmony.
