Symbolism also played an important role in establishing a sense of order. Symbolism, ranging from the Pharaoh's regalia (symbolizing his power to maintain order) to the individual symbols of Egyptian gods and goddesses, was omnipresent in Egyptian art. Animals were usually also highly symbolic figures in Egyptian art. Color, as well, had extended meaning—blue and green represented the Nile and life; yellow stood for the sun god; and red represented power and vitality. The colors in Egyptian artifacts have survived extremely well over the centuries because of Egypt's dry climate.
