Solar symbols can have significance in psychoanalysis, symbolism, semiotics, astrology, religion, mythology, mysticism, divination, heraldry, and vexillology, among other fields. A simple circle or circular disk can be a solar symbol, as in the flag of Japan, the flag of Bangladesh, and the Australian Aboriginal flag, or in three-dimensional form as part of the Trundholm sun chariot.
