The television show Lost includes a number of mysterious elements that have been ascribed to science fiction or supernatural phenomena, usually concerning coincidences, synchronicity, déjà vu, temporal and spatial anomalies, paradoxes, and other puzzling phenomena. The creators of the series refer to these as part of the mythology of the series.
As the main setting of the series, the island boasts a number of unusual properties. Its location changes at times and it cannot be reached by ordinary means. The island is surrounded by some sort of barrier which causes disruptions in the normal flow of time for those who cross it. Electromagnetic phenomena are common on the island, and it seems to bestow unusual healing properties to its residents.
Located deep inside the jungle is the Black Rock, a sailing ship from the mid-19th century. In "Ab Aeterno", the Black Rock set sail in 1867 and was captained by Magnus Hanso and had Richard Alpert as a prisoner. Jacob, the protector of the island, does not deny when asked by his fraternal twin brother if he brought the ship to the island, as the two watch it approaching. Eventually it is swept inland by a colossal rogue wave, destroying all but one foot of the coastal Statue of Taweret on its way, but a mystery remains on how The Black Rock had landed on almost the other side of the Island from where the statue of Taweret was. In "The Constant", it is explained that the Black Rock set sail from Portsmouth, England, on March 22, 1845 on a trading mission to the Kingdom of Siam, when she was tragically lost at sea. The only known artifact of this journey is the journal of the ship's First Mate, which was discovered among the artifacts of pirates on Île Sainte-Marie, Madagascar seven years later. The contents of this journal have never been made public nor known to anyone outside the family of the seller Tovard Hanso. This journal is later bought at auction by Charles Widmore.
