— The Seer to John Alden

Petrus, most commonly known as The Seer, was a gifted cunning man [1] and a recurring character in Salem. He lived deep in the woods preferring the company of his familiars than his own kind. Poor and blind, he used his familiars as his eyes in the woods so nothing will go unnoticed by him.

He was portrayed by American actor Christopher Berry.


Petrus has a quirky personality, speaks often with its cockroaches and with the stuffed animals that uses as familiars to send to spy on witches's enemies(or the same witches). He was seen eating the larvae and cocoons while chasing Mary Mercy in the woods.

Physical Appearance

Petrus was a man in his thirties, with blonde hair styled in a similar way to some Indian tribes. The eyes were very blue clear so as to suggest that he was blind and who see through the magic. He also has a badly shaved beard and worn clothes.

Early Life

Virtually nothing is known about his early life, but we know that his dream is to go to the South. According to Tituba's words, Petrus owes her his loyalty.

Throughout the Salem Serie

Season One

In The Stone Child, Magistrate John Hale went to the cabin in the woods so that the seer Petrus discover the identity of the person who has broken the Sabbath's circle. The witch then takes the lizard and after having engraved its eyes, let the blood drip into a bubble of glass full of water in which the blood floats until it took on the appearance of Isaac Walton and John Alden's faces.

In In Vain, TBA

In The Red Rose and the Briar, the seer is visited by Tituba and the two have an altercation that Tituba has or has not power over Mary. Petrus fact saw Mary in the woods with Mercy practicing the ritual to create a new witch.

In Departures, TBA

Season Two

In Cry Havoc, Petrus is approached by Mary who asks him to use clairvoyance to find John Alden.

Powers and Abilities

Petrus 106

Petrus at his working table

Petrus was a cunning man and a seer, and as such, he was a divination expert and an excellent clairvoyant. His powers were connected to that of some stuffed animals stored in his hut, which he used when needed to have eyes everywhere. These stuffed animals were acting similarly to a witch's familiar, except that they were creations of his cunning craft instead of gifts from the Dark Lord. When required, Petrus was also able to revive these stuffed animals, either for personal defense or to get visions; Therefore it can be assumed that Petrus must hold some powers over the Nether Worlds in order to raisig the dead.

Petrus was also a connoisseur of herbs, barks and roots that he used to prepare poultices and concoctions resorting to cunning crafts nearly powerful enough to equate witchcraft. In addition to the supernatural abilities, Petrus was an expert of paths and tracks, and was highly skilled in moving undisturbed in the woods, crossing them without leaving any trace or making noise. Petrus' extensive knowledge of the area and the study of tracks allowed him to reach any destination and, when added to his clairvoyant skills, he was able to track down anyone with ease.

Petrus (to Tituba): You're no more witch than I was. We are the cunning ones. When you ate my eyes, you swallowed my vision. My very essence as a Seer. Now bear the the responsibility I bore.
--After the Fall
Petrus (to Tituba): See what I see. What you and the Essex witches have done by bringing back the Devil himself and handing this earth over to him. This is your future under the Dark Lord. Yet the future is not a single thread, but a shifting tapestry of infinite threads. And there's only one way to change the future... You and Mary Sibley gave the Devil the Earth. Now you and Mary Sibley have got to take it back.
--After the Fall




  • His role as Seer is useful to the witch hive as he works as a spy and informer of any current and future threats thanks to his natural inclination with divining powers.
  • According to Mary Sibley, his "eyes are everywhere and can go anywhere."
  • Petrus was an expert taxidermist.
  • Christopher Berry described the character he played as:

"Petrus is quite blind and he can see through the eyes of his animal companions. What we know about Petrus is he does appear to have some powers, a witch sort of view. Petrus is a cunning man, which is an actual thing from early Middle Ages up to 18th century. They were who you'd come to if you wanted a love spell, let's say. Or if you want to combat a witch, or find a witch you would consult a cunning person to help you identify them. Petrus is helping the witches. Is not necessarily clear whether he's doing it because is compelled to or because he has his own agenda. He is more than misty eyes." [1]
