Sun

As a symbol, the sun has many meanings. It represents the supreme cosmic power, the all-seeing divinity. It is the heart of the cosmos, the center of being and of intuitive knowledge; the intelligence of the world; enlightenment; glory, splendor; royalty; God the Father, ruler and sustainer of the Universe. It can be a symbol of spiritual illumination, joy and happiness.

In the Tarot Decks, the sun is the XVIIII -th (they tend to put XVIIII instead of XIX) card of the Major Arcana.

Over view of common meanings as a symbol:

Life and Vitality The Sun is the ultimate symbol of life itself—it provides warmth, light, and energy that makes existence possible. It represents vitality, health, and the life force that animates all living things.

Illumination and Knowledge As the source of light that banishes darkness, the Sun symbolizes enlightenment, truth, consciousness, and rational thought. It's often associated with clarity, awareness, and the revelation of hidden things.

Power and Authority Many cultures have associated the Sun with divine power, kingship, and sovereignty. Think of Louis XIV as the "Sun King" or the sun gods in various mythologies (Ra, Apollo, Helios). It represents supreme authority and cosmic order.

Renewal and Cycles The Sun's daily journey—rising, setting, and rising again—symbolizes rebirth, resurrection, and eternal return. It embodies the cyclical nature of time and the promise of new beginnings.

Masculine Energy In many (though not all) symbolic systems, the Sun represents masculine principle—active, outward, yang energy—in contrast to the Moon's feminine, receptive qualities.

The Self and Consciousness In psychological symbolism, particularly in Jungian analysis, the Sun often represents the conscious self, ego, and individuality—the center of one's psychological universe.

The Sun's meaning can shift depending on context—in astrology, alchemy, religion, literature, or personal symbolism—but these core associations tend to persist across different interpretations.
