The Witch corr. 2

 5. Witches existed in the late Middle Ages and the Renaissance period under the name "wise women" (and wise men). They lived outside of society and would service the community in different ways. They still exist today in different forms and shapes. 

But they would sometimes be accused of Maleficium, that is, using their gift to promote evil. One such wise woman was Ursula Kempler. She was tried for corrupting crops (de corrompre les récoltes) ; she confessed having familiars (they could be toads, cats, dog, hares, goats...). In the movie, the witch lives in the forest, on her own.

Traditional representations of witches describe them by groups of three. These are reminiscent of the Greek Moirai, or Fates, who presided over the destiny of men and gods. 

6. there are fantastic elements before Thomasin speaks with the goat and turns into a witch = when Caleb spits the apple, or when Sam is kidnapped.
