What is an 1600 witch?

A dead witch. In 1692, there were the Salem Witch Trials, and I must say that an awful lot of women were burned, both innocent and guilty, because they were accused of witchcraft simply because they could heal people that (male) doctors couldn't. People have always been afraid of things they know nothing of, and that's why witches in the 1600s were feared above most else.

EDIT:

First, in Protestant England and America, witches were hanged.

Second, only 14 women died in the Salem Trials.

Third, Every victim of the Salem panic was innocent.
