The Pied Piper story you know isn't the original story

Discover how the Pied Piper legend changed over time, and why the rats in the story may not have been there at the beginning.

The Town Was Overrun with Rats!

Ask someone to tell you the story of the Pied Piper of Hamelin and there's a good chance rats will appear within the first few sentences…

The town of Hamelin is overrun with them. A mysterious piper arrives and offers to get rid of them. He plays his pipe, the rats follow him, and he leads them away; usually into the River Weser, where they drown.

Then comes the part that makes the story so memorable.

The townspeople refuse to pay him.

So the Piper returns.

This time, when he plays, it isn't the rats who follow him. It's the children – never to be seen again.

It's a wonderfully dark story. It has everything a good legend needs: a mysterious stranger, a broken promise, revenge, music, magic, and a terrible ending.

There's just one problem…

That isn't the original story.

‎‎‎‎⠀

Where are the rats?

If we go back to the earliest surviving evidence connected with the Hamelin tradition, something rather conspicuous is missing.

There are no rats!

🐀 The oldest version of the story isn't about a town plagued by vermin.
🐀 It isn't about an unpaid rat-catcher.
🐀 And it isn't about revenge for a broken contract.

At its heart is something much simpler, and perhaps much stranger.

On 26 June 1284, 130 children of Hamelin were said to have left the town with a man (sometimes described as a piper, sometimes a magician) and disappeared.

That is the event around which the earliest tradition seems to have formed.

The rats came later… Much later.

‎‎‎‎⠀

A story built in layers

This is one of the things that makes the Pied Piper legend so fascinating to research.

There isn't really one fixed Pied Piper story that has travelled unchanged from 1284 to the present day.

Instead, the story seems to have accumulated layers…

• The disappearance of the children is old.
• The Piper is old.
• The date, 26 June, is old.

But other familiar parts of the story appear in the surviving sources at different points.

🐀 The rats are one of them.
🐀 The idea that the Piper was hired to remove the rats is another.

The refusal to pay him gives the story a motive: now we know why he takes the children.

And once that element is added, the mysterious medieval story begins to turn into the much more recognisable tale of promises, punishment and revenge that most of us know today.

Which raises an intriguing question…

‎‎‎‎⠀

How did the mystery become a story?

Stories don't like gaps or unfinished endings.

Neither do people.

If an old tradition says that a mysterious Piper led 130 children away from Hamelin, the obvious question is: Why?

Perhaps that's exactly the sort of question generations of storytellers tried to answer.

Why was the Piper there?
Why did the children follow him?
Why would he take them, and what would he do with them?

The rat-catching episode provides beautifully satisfying answers.

He was there because the town had rats.
The townspeople hired him.
They broke their promise.
He took the children in revenge.

Suddenly, an unexplained disappearance has a beginning, a cause, and a moral.

But a satisfying story isn't necessarily an older one.

And that's where things become interesting for anyone trying to work out what, if anything, might lie behind the legend.

‎‎‎‎⠀

Working backwards

One of the aims of The Hamelin Project is to do something slightly different from simply retelling the Pied Piper story.

I want to work backwards; instead of beginning with the familiar tale and asking whether it could have happened, we can strip away the later additions and ask:

What do the earliest sources actually say?

• When does each part of the story first appear?
• Which details can be traced back for centuries?
• Which appear surprisingly late?
• And what happens to our understanding of the mystery when we remove the rats altogether?

Because perhaps the most intriguing Pied Piper story isn't the one most of us know...

It's the one that existed before anyone thought to add the rats.‎‎‎
