(Disease & Disaster) “The Witches Curse” poses a shocking new idea about the violent convulsions, delirium, and strange skin sensations that struck a group of young girls in 17th-century Massachusetts and inspired the infamous Salem Witch Trials. In 1692, 19 of the town’s residents were put to death because they were believed to have been witches. For hundreds of years, this tragedy was blamed on religious fanaticism, adolescent cruelty, and contagious hysteria. But these explanations failed to satisfy a “detective” who embarked on her own fact-finding mission. Was Salem’s Puritan community unwittingly living on bread infected by the fungus from which LSD is derived? Could toxic amounts of this fungus, known as ergot, be the real reason the accusatory teens endured psychotic episodes and saw blood dripping down their walls at night? And what clues could the 2,300-year-old corpse of a Danish murder victim possibly hold for Salem investigators? Tracking down historic outbreaks of ergot poisoning, Dr. Caporael compares its symptoms to those that plagued the girls in Salem, revealing a whole new side of this unsettling period.

A mysterious skeleton buried in a shallow grave beneath a famous ancient monument. Who was he? How long had he been there? And why had his head been severed from its body? Archaeologist Mike Pitts works with scientists, forensics experts and historian to dig up ominous information about early Britain and the circumstances that surrounded the man's death. Was he a cattle thief, an insurgent, or a pagan sacrifice in a newly Christian world? (UK/PBS 55 min)

The settlers at Jamestown, the first British colony in the New World, were looking for wealth and adventure. But within six months 80 of the original 100 arrivals were dead; 440 of the first 500 died within three years. Death came in sudden, brutal waves marked by severe bruising, weakness, wasting and madness. Did the men die of disease and starvation? Or is it more than a coincidence that the deadly outbreaks always seemed to strike just after the supply ships set sail? Clues from Europe and the recently rediscovered Jamestown site have led pathologist Frank Hancock to a radical new theory that implicates some unlikely suspects. (UK/PBS 55 min)

For centuries, visitors to the Church of the Holy Seplulchre in Jerusalem believed that they stood within what was merely a symbolic representation of Jesus' burial place. But what if the edicule within the church, an ancient crumbling structure, really does house Christ's actual tomb? Oxford archaeologists Martin and Birthe Biddle reconstruct Jesus' final day and trace the history of the various incarnations of the edicule -- looking for evidence that there is a tomb present, and trying to decipher whether or not Christ actually lay there.

In 1492, Christopher Columbus crossed the Atlantic in search of gold. But what his men carried back with them to Europe was something far less appealing. They brought the scourge of syphilis, a sexually transmitted disease never before seen in the Old World. At least that is what scientists have generally believed. But now, the discovery in Europe of a pre-Columbian body with definite signs of syphilis has archaeologist Charlotte Roberts convinced that syphilis existed in the Old World long before Columbus ever set sail. New evidence from across Europe is beginning to turn the prevailing Columbus theory on its head (UK/PBS 55 min)
