>There are validated European accounts of these events throughout the 1800's and early 1900's.
It is always interesting when the cases are analysed by modern Anthropological Pathologists. The underlying causes of the deaths are often found to be common illnesses, some easily curable with modern medicines.
I saw one such example in a documentary on Egyptian tombs, where a woman visiting King Tut's tomb died after touching the walls. Her air passages had been infected with mold spores. She was just recovering from a lengthy battle with cancer so her body could not combat the spores, but most visitors to the tomb never have that problem.
Imagine the same scenario happening when they opened the tomb. It would have been a great mystery and definitely blamed on the curse.
