A snake, drawn coiled, reared, entwined in pairs, or hooded above a head. It is cut into rings and pendants, cast on the branches of Neapolitan silver charms, hooded in stone over Angkorean doorways, and worn as the cobra on an Egyptian crown. Nothing else in this atlas is so evenly split between a thing to be guarded against and a thing that does the guarding.

The story

Snakes make good guardians for a reason their observers state plainly: a cornered cobra or rattlesnake holds its ground, displays, and fights rather than retreating. So it gets set where something cannot be moved out of harm's way. At Angkor, hooded multi-headed nāgas guard temples in stone, and from about the twelfth century CE a favourite subject was the Buddha meditating on the coils of a nāga whose flared hood shields him — the story of Mucalinda, who came up from the roots of a tree when the storm began.

Egypt puts the snake at the top. Wadjet, the Egyptian cobra, is from the earliest records the patron and protector of the country, of the other gods and of the pharaohs, worn entwined around the papyrus staff and set in the crown. Nehebkau, the two-headed serpent, guarded the entrance to the underworld, and charms against snakes were inscribed or chanted invoking him — which is the whole ambivalence in one deity: the snake keeps snakes off.

The entwined pair is older than the caduceus. The oldest known representation of two snakes coiled round a rod is the Sumerian god Ningizzida, later a god of healing and magic; a green steatite vase carved for King Gudea of Lagash, dated variously to 2200–2025 BCE, carries an inscription dedicated to him and is in the Louvre. The Greek physician Asclepius carries the single-snake staff that modern medicine still uses. Moses set a serpent on a pole, the Nehushtan, at Numbers 21:8.

Europe kept a domestic version. German popular belief records the house snake that looks after the cows and the children, whose appearance is an omen of death, and whose life is often held to be bound to the master's and the mistress's.

Inference — the snake turns up in this role on every inhabited continent, and the sources read here do not show one tradition teaching another. Where the same posture appears — reared, hooded, entwined — the likeliest account is that people in many places watched the same animal do the same thing.
