Why Sacred?
 70 A.D In the Gospel According to
Mark (9:14-29)
Jesus Christ casts out a devil from a
young man with epilepsy:
"Teacher, I brought you my son,
who is possessed by a spirit that
has robbed him of speech.
Whenever it seizes him, it throws
him to the ground. He foams at
the mouth, gnashes his teeth, and
becomes rigid. I asked your
disciples to drive the spirit out, but
they could not." (NIV)
Raphael: The Transfiguration – www.epilepsiemuseum.de
1494: A handbook on witch-hunting
Written by two Dominican friars under papal authority, the book
identifies the presence of seizures as a characteristic of
witches. Malleus Maleficarum brings a wave of persecution
and torture, leading to the death of more than 200,000
women.
