The Altenburg rat king
In 1828, a miller at Buchheim (Saxony) found 32 rats with their tails tangled together in a chimney; the mummified 'rat king' is kept at the Mauritianum museum in Altenburg.

The account
Rat kings were seen as bad omens in German folklore. The Altenburg specimen is the largest preserved one.
The sceptical view
How rat kings form is not certain. Proposed causes include sticky material and cold, but some may have been man-made curiosities.
The researched reading
A real mummified knot of rats. Natural tangling in a crowded nest is the leading explanation, and human manufacture is a serious alternative. The only mystery is how it formed, and only ordinary causes are in contention.
| Explanation | Weight | Why |
|---|---|---|
| Undetermined | 42% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| Something known, misidentified | 40% | The specimen is real and made of ordinary black rats. Tails can tangle naturally in crowded nests, glued by dirt, sap, frost or excrement. A living rat king was found in Estonia in 2005, and X-rays of specimens show tail fractures that healed, so the animals lived while knotted. |
| A cultural story | 10% | German folklore made the rat king an omen of plague, which explains why it was kept and displayed. The lore does not explain how it formed. |
| A hoax or fabrication | 5% | Rat kings were saleable curiosities, and some are suspected of having been tied together by people. A knot of 32 rats is unusually large, which raises the odds of human help. |
| An unknown or out-of-place animal | 1% | Ordinary rats, not an unknown species. |
| Perception, memory or mind | 1% | The object is physical, so perception plays no part. |
| Genuinely anomalous | 1% | Nothing physically inexplicable is involved. |
Official position: The Mauritianum museum presents it as a genuine natural specimen whose formation is not fully understood.
