belgian noble woman

[ymaras]

which belgian noble woman was sentenced to death for bathing in the blood of servant girls she had murdered in order to keep her young

[BrainMonkeys]

Her name was Elizabeth Bathory, and she was Hungarian (aren't they all?!).

In truth, she was a Countess who had a side-line of serial killings; the whole blood of virgins is a myth.

The reason, they say, she did that is because when menstruating she would loose iron in her blood and by drinking blood (which she also did) she would gain that iron back. They say she saw her complexion turn rosier, so believed she was growing younger.

sorry, not exactly an answer to your question, just a comment

Elspeth (Elizabeth) Bathory, 1560 - 1614, did her infamous work in Cachtice Castle, Transylvania ; locally known as the 'Castle of Vampires'.
It is estimated that c. 650 young girls were tortured by this
'lady', and then murdered.
At her trial, two accomplices, Iloona Joo and Dorothea
Szentes, were sentenced to have their fingers torn out by
the public executioner, then thrown alive onto a fire.
At the same trial, January 1611, Elspeth was condemned to be walled-up in her own castle. She died July, 1614.
