Ergot Bread from Salem

Origin
The Salem witch trials were a series of hearings and prosecutions of people accused of witchcraft in colonial Massachusetts between February 1692 and May 1693. The trials resulted in the executions of twenty people, most of them women. Despite being generally known as the Salem witch trials, the preliminary hearings in 1692 were conducted in several towns in the Province of Massachusetts Bay: Salem Village (now Danvers), Salem Town, Ipswich and Andover. The most infamous trials were conducted by the Court of Oyer and Terminer in 1692 in Salem Town.

Effect
This half-eaten loaf of bread was contaminated with ergot, causing hallucinations. It was collected and preserved at an unknown time. The bread causes hallucinations of demonic figures, and can affect people that are simply near the bread. Touching, and especially eating the bread, is highly prohibited.
