Concerning Isildur and Sauruman

[lindil]

It seems more likely to me that after that many years it would be buried deep in the earth by then and I don't think Sauruman had any metal detectors. A more likely although not supported in any other way than probability is that someone else found the treasures and were either taken or given to Sauruman.

Well Saruman was the first to come up with 'Blasting Powder' as I recall. So perhaps he was creating other such technologies such as an ability to sense metal. Or maybe there was a shifting of the river, and what had been covered in mud was exposed.

It does however seem plausible that the elements would have had their way with all but non-corrosive/decaying metal.

Of course the ring being in the reeds 2.5 thousand[?] years later is pretty odd too.
