Serpent
The serpent means opposite things across cultures: evil and death, and also life, renewal and cosmic order. The Norse world serpent Jörmungandr circles the earth, the nāga Shesha carries Vishnu on the cosmic ocean, the Ouroboros eats its own tail, and the snake on Asclepius’s staff still stands for medicine.
Meaning
Manfred Lurker, writing on snakes for the Encyclopedia of Religion (1987), puts the paradox at the start: snakes “are thought of as evil and as a cause of death; on the other, they are believed to embody beneficial and even divine powers”. His examples come in pairs. In Egypt, the serpent Apophis was the worst enemy of the sun god Re, and the serpent Mehen protected Re on his journey through the underworld. In the Bible the serpent tempts Eve in Genesis, and the bronze serpent Moses raised on a pole in Numbers is, in Lurker’s reading, a symbol of life. In India Krishna defeats the serpent Kaliya, and the serpent Shesha is Vishnu’s couch. Nāgas are still honoured in Hindu tradition at the festival of Naga Panchami (Britannica). The everyday side of snake lore is on the snake page.
Origin and history
The world serpent is the serpent at the largest scale. In the Prose Edda, Alfather (Odin) throws Jörmungandr, one of Loki’s children, “into the deep sea which surrounds all lands. There waxed the serpent so that he lies in the midst of the ocean, surrounds all the earth, and bites his own tail.” Britannica calls him Thor’s chief enemy, and at Ragnarök they kill each other: “Thor gets great renown by slaying the Midgard-serpent, but retreats only nine paces when he falls to the earth dead, poisoned by the venom”. Lurker sets beside him the Ouroboros of classical antiquity, the serpent “which swallows its own tail” and so “is able to embrace the entire universe”, and Indian images of the dancing Shiva inside a ring made of a serpent’s body. The Ouroboros has its own page, and so does Jörmungandr’s enemy, Thor.
In Indian tradition the great serpents are nāgas, “half human and half cobra” in Britannica’s words, guardians of waters and treasure, who live in an underground kingdom. Three are famous: Shesha, or Ananta, on whom Vishnu lies on the cosmic ocean; Vasuki, the rope with which gods and demons churned the ocean of milk, turning the world mountain Mandara “like a creative whisk” (Lurker); and Takshaka, chief of the snakes. Lowell W. Bloss, in the Encyclopedia of Religion, describes nāgas as fertility deities older than the Hindu and Buddhist pantheons that took them in, shown as cobras “with one or many hoods”, and notes the Buddhist story of the nāga king Mucilinda sheltering the Buddha with his coils and hoods. The drawing on this page is a many-hooded nāga.
In ancient Mexico, Lurker writes, Quetzalcoatl and Tezcatlipoca turned themselves into serpents and tore the primeval water monster in two to make heaven and earth. Quetzalcoatl, the Feathered Serpent, has his own page: Quetzalcoatl.
The serpent and immortality
Lurker draws a line between the snake’s skin and its meaning. Because it sheds and renews its skin, the serpent “becomes a symbol of death and resurrection”, and he quotes Mircea Eliade calling it “an epiphany of the moon”. The same idea runs through stories of lost immortality: Gilgamesh finds the plant of immortality and a serpent steals it while he bathes; in Genesis, “the serpent was more subtil than any beast of the field”.
The serpent on the healer’s staff
The snake belonged to gods of healing, Lurker writes, Shadrapa in ancient Syria and Asclepius in Greece, the Aesculapius of the Romans. Ovid tells how the god came to Rome as a serpent; in a dream he holds a rustic staff and says, “Only observe this serpent, which with its folds entwines around this staff … Into this shall I be changed.” Lurker calls the staff with the snake “still the symbol of the medical profession” and adds “(the caduceus)”, a common confusion: the rod of Asclepius and the caduceus are different emblems, each with its own page. The bronze serpent of Moses, “a serpent of brass” put “upon a pole” (Numbers 21:9), is a separate story that Lurker counts as the Bible’s serpent of life.
The serpent as royal power
In Egypt the cobra stood for kingship: the uraeus the pharaohs wore on their foreheads was, Lurker writes, “a symbol of their sovereignty”, and the serpent on the brow of Re destroyed his enemies. Britannica’s article on dragons sets the other Egyptian serpent beside it: “the Egyptian god Apepi … was the great serpent of the world of darkness”. Dragons, which began as serpents, are on the dragons across cultures page.

The winged sun disc of Egypt and Assyria, the Babylonian sun god’s four-pointed star in a disc, the gold disc of the Trundholm Sun Chariot and the chariot wheels of the Sun Temple at Konark each belong to a named tradition.
- The Ouroboros, the serpent that swallows its own tailOuroborosA serpent curled into a circle with its tail in its mouth. The oldest known example is on a gilded shrine of Tutankhamun; Greek alchemists in Egypt later drew it around the words “the all is one”, and since the Renaissance it has usually been read as eternity.
