Why are there so many different versions of the Pied Piper story?

Why has the Pied Piper story changed so much over seven centuries? Following the clues through the surviving sources.
⠀
This week, I found myself reading the comments beneath a YouTube video about the Pied Piper of Hamelin.
Within a remarkably short space of time, the children had been drowned, killed by disease, found in a cave, murdered in connection with a pagan cult, and turned into trees.
The trees were new to me.
But somewhere among the increasingly imaginative fates of Hamelin's children was a rather good question.
Why are there so many different versions of the Pied Piper story?
⠀
The story we think we know
Most of us probably think we know the story:
A mysterious piper is hired to rid Hamelin of its rats.
When the townspeople refuse to pay him, he returns and leads away their children instead.
Simple enough.
Except the further I get into the historical sources, the less simple it becomes.
Working backwards through the sources, familiar elements begin to disappear. Different accounts offer:
◇ different descriptions of the Piper;
◇ different ideas about where the children went;
◇ different explanations for what happened to them; and
◇ different attempts to explain, correct or reconcile earlier versions.

More than seven centuries of storytelling
There is another part of this that is very easy to overlook: time.
We can read the date 1284 without really stopping to think about what it means. But 1284 was more than seven centuries ago!
The story associated with Hamelin has had over 700 years in which to be remembered, retold, written down, copied, translated, interpreted and reinterpreted.
Think of the childhood game where a message is whispered from one person to the next. By the time it reaches the end of the line, it can bear remarkably little resemblance to what was said at the beginning.
Now imagine giving a story seven centuries.
Of course, historical transmission is much more complicated than a game of whispers. Some of the story may have circulated orally, while other versions were preserved in writing. And even written stories don't necessarily remain untouched.
Over time, people:
✦ select what to include;
✦ interpret what they read;
✦ try to explain things that no longer make sense to them;
✦ repeat details inherited from earlier accounts; and
✦ encounter other versions.
And sometimes they add rats.

A story with a history of its own
That's one of the things I've found most fascinating about working backwards through the sources. It's very easy to imagine the Pied Piper story as something that happened, or was invented, in a particular form and was then handed down through the centuries, becoming slightly muddled in the retelling.
But that isn't really what the evidence looks like. The story has a history of its own.
Successive writers encountered traditions that already existed, but not necessarily in the form we know today: Writers copied earlier writers; details were added or dropped; explanations were proposed.
Later versions became familiar enough that their details began to feel as though they had always been there.
The rats are perhaps the perfect example. They are absent from the earlier accounts we've encountered.
That doesn't make the variations an irritating obstacle that we need to clear away before we can get to the "real" Pied Piper story.
The changing story is itself part of the history.

Following the story backwards
For The Hamelin Project, that means I'm becoming increasingly interested not only in what a source says, but in when it says it.
When do the rats appear?
When does a particular explanation for the children's disappearance first turn up?
Where did one writer get his information from?
And can we follow a detail backwards through the sources until, eventually, it disappears?
⠀
Those questions may not tell us what happened in Hamelin in 1284. But they can tell us how the story we recognise today came to exist.
As for the children turning into trees...
I'll keep an open mind.
For now. 🌳⠀
