Narwhal tusk

The Narwhal tusk joins material strangeness to centuries of human projection: a living tooth became a unicorn horn, a royal object, and a supposed cure before its biological properties could be examined. In the book, its history turns on the gap between what people made the tusk mean and what it is—a sensitive organ, and also a material shaped by practical use.

Anatomy and Sensory Function

The tusk is an overgrown tooth that erupts through the Narwhal’s upper lip on the left side and may spiral to nine feet or more. Its shape made it look like a singular ornament, but microscopic examination disclosed a very different kind of structure: unlike other teeth, its surface has open tubules connected to inner nerves. The tusk is described as a giant sense organ, with ten million nerve endings that allow the animal to detect subtle changes in temperature and pressure.

That sensory account gives a possible explanation for Narwhals raising their tusks above the water, as if sniffing the air. Research also suggests the tusk may transmit or receive sound and even electricity. These functions exceed the magical capacities once attributed to it, while making the apparent marvel biological rather than supernatural. The tusk is not inert ivory: it is an enervated growth associated with tactile sensation, which the cited research suggests may be pleasurable.

The book also revises the customary interpretation of males rubbing their tusks together. The behavior had been taken as a contest over females; the sensory properties of the tusk indicate that this explanation is incomplete. Its sensitivity has consequences when it is damaged: the account describes another Narwhal placing the tip of its own tusk into the exposed space and breaking off the end to plug it. The gesture presents the tusk not simply as a weapon or display, but as a vulnerable organ within an animal’s social life.

Unicorn Legend and Royal Value

For centuries, the tusk was mistaken for a unicorn’s horn and invested with magical power. A medieval trade joined Arctic hunters and apothecaries in passing the natural object off as a legendary one. Tusks were prized booty, valued at twenty times their weight in gold, stolen by Crusaders, and traded across Europe as state talismans. By the mid-sixteenth century, only fifty were known to exist.

In 1577, after an expedition seeking the North-West Passage, Sir Martin Frobisher presented Elizabeth I with a supposed sea-unicorn horn valued at £10,000—more than the cost of a new castle. She used it as a sceptre. The tusk thus entered a language of royal authority: its value rested not only on rarity and precious material, but on the legendary power attached to it. The account marks 1685, when Francis Willughby described the Narwhal, as the point at which the fraud was exposed and the animal’s reality became harder to evade.

Melancholy and Symbolic Meaning

The tusk’s supposed powers extended beyond its use as a talisman. Powdered tusk was valued as an antidote to poison and melancholy, the condition Robert Burton had documented and Herman Melville had studied. The account links this association with a literary reading of Albrecht Dürer’s 1514 engraving Melencolia: its brooding angel and comet over a distant sea provide, for Viola Sachs, a hidden structure based on a magic square of four. In Sachs’s interpretation, that cipher connects Melville’s theme of melancholy with Ishmael, the biblical outcast, and expresses a vision of creation’s terrestrial origin.

These layers of belief make the tusk a symbol burdened by its own elaborate history. Its spiralling extension, which the book compares in its weight and appearance to carved stone and a cathedral gargoyle, seems to belong as readily to a fairy tale as to an animal. Unicorns continue to be portrayed with a Narwhal-like horn. The object’s cultural afterlife therefore persists even after its supposed magical identity has been corrected: scientific explanation alters what the tusk is understood to be, but does not erase the image it has supplied to legend.

Practical Uses and Human Claims

For Inuit communities, the Narwhal is described as a utilitarian catch, and the tusk has uses distinct from its European career as a relic. It can be made into fishing rods; Inuit carvers also shape tusks into decorative objects. The narrator calls that ornamentation useless beside the beauty of the natural form, a judgment that contrasts aesthetic admiration with practical use without removing the tusk from either sphere.

The Narwhal’s tusk is thus repeatedly made to serve human purposes: as a cure and state treasure, as the model for a mythical horn, and as material for tools and carved objects. Against those claims, the account’s description of its nerves and sensory capacities restores the tusk to the living animal. What had seemed an isolated spike of ivory emerges instead as an organ whose significance cannot be reduced to the meanings or uses people have assigned to it.
