The stag is a male deer, sometimes known as a hart. It has fascinated people for thousands of years, because its antlers are renewed every year. Cave paintings, dating from the Paleolithic period, frequently depict stags, as well as people wearing antlers and the skins of stags. The ancient Celts believed that stags acted as a guide to souls and helped them move into the next world. Animals with horns are traditionally linked with male sexuality. Because of this, horns are frequently ground to powder and used as aphrodisiacs. For the same reason, stags are also associated with fertility, potency, passion, and power. However, during the Middle Ages, the stag was considered a sign of purity. Both St. Eustace (early second century CE) and St. Hubert (656-727) were said to have become Christians after seeing a glowing crucifix between the antlers of a stag. King Richard II (1367-1400) used a white stag as his emblem. Because stags are solitary animals, they have also become a symbol of loneliness and melancholy. To dream of a stag is usually a sign of repressed sexuality. However, it can also be a sign of self-enforced loneliness that is continuing too long for your mental well-being.
