I’m sure I read somewhere that there was a prophecy that Isengard would stand until the forest moved against it, or something to that effect. However, I cannot figure out where I got that from.
I thought it was actually the reason why he intentionally destroyed the forest. He was trying to prevent the prophecy while actually causing it.
Yet, I cannot find any proof of this. Did I just imagine this?
The image came from here.
You may have picked it up from Shakespeare. In Macbeth, he is given the prophecy
“Macbeth shall never vanquished be until
Great Birnam Wood to high Dunsinane Hill
Shall come against him”
Macbeth takes this to mean he is safe if the forest never grows near his castle.
That’s amazing! You’re right, I must have read something like the following and combined the two in my mind.

Thanks for this. I was not aware of the direct attribution by JRR, but it doesn’t surprise me.
So much of English lit is inspired by Shakespeare.
