Tengu (天狗)

It began as a star. The "tengu" recorded in ancient Chinese texts referred to a meteor that tore across the heavens like a howling dog. People looked upon that light rending the sky as an omen of calamity, gave it the shape of a hound, and feared it.

The name was first inscribed in Japan in the seventh-century chronicle Nihon Shoki. Concerning a great star that had streaked across the capital with a thunderous roar, the scholar-monk Min — newly returned from Tang China — spoke quietly and without equivocation: "That was no shooting star. That was a tengu." With those few words, he opened the long door of transformation that would carry the celestial beast down from the sky and into the mountains.

When the tengu reappeared in the Heian period, it was no longer a star racing through heaven. It had become something uncanny lurking in the deepest reaches of the mountains, in territories no human foot could tread. The notion of the "tengu realm" took shape — a plane into which mountain ascetics who had drowned in vanity and ambition were said to fall after death — and the tengu came to be spoken of as the destination awaiting the arrogant soul.

The form that settled into common knowledge in later centuries is well known: a flushed crimson face, an impossibly tall nose, the robes of a mountain ascetic, single-toothed geta clogs, and a feathered fan. It soars through the sky at will, bewitches the minds of men, and lures them toward ruin. Yet that silhouette is one painted over and over across the ages, and beneath it something far older still lies sediment — an unnameable presence that has always breathed within the mountains.

Those who vanish without trace in the high peaks, those who fall into inexplicable madness — even now, the elders of mountain villages whisper that such people have been "carried off by a tengu." Suspended between reverence and dread, this strange being refuses to be fixed as either god or monster, and so it goes on standing in the mist, neither one thing nor the other.
