Timeline:Pre-crash

Miscellaneous trivia

Prior to Twentieth Century

Indeterminate time in past

Before Jacob and his brother's birth

• A woman comes to the Island "by accident" and somehow becomes the protector of the Source. ("Across the Sea")

Very likely before Jacob's birth

• The structures known as the Ruins are built and then permanently abandoned.
• The Taweret statue is fashioned and erected.
• Elements of the Temple complex are constructed.
• The fourteenth time flash occurs, while the statue of Taweret was still standing fully intact, before the Orchid well was dug.

About two millennia before the crash of Flight 815 (Roman period)

• An ancient ship, crewed by Latin-speaking people, is wrecked off the coast of the Island. Much of the crew make it to the Island. ("Across the Sea")
• The next day, Claudia comes ashore at another part of the Island, where she is discovered by the mysterious woman. Claudia gives birth to twins, Jacob and his brother, before being killed by the woman, who becomes adoptive mother to the twin boys. ("Across the Sea")

13 years later

• The shipwreck survivors have built a thriving community of yurts and go on hunting expeditions deep into the forest. ("Across the Sea")
• Jacob and his brother discover the evidence of other people for the first time while hunting a boar. Their mother shows them the Source, and explains little of their destiny to protect it. Claudia visits her son in spirit, and Jacob's brother attempts to coerce Jacob into leaving for the other camp, but is beaten by Jacob and leaves Jacob and his mother for the camp. ("Across the Sea")

30 years after the shipwreck

• Stonework and water-channeling system as a type of underground shrine are built for the Heart of the Island.
• Jacob's brother, having attained position in the other camp, has constructed a well in the hopes of reaching the Source and escaping the Island. While meeting with Jacob, he expresses hatred of other people and confirms his overriding desire to leave the Island. When his mother learns of the efforts by Jacob's brother, she visits him at his excavations where he is succeeding to access the Source. She then proceeds to knock him out, bury his work, and kill all the other people, destroying their village.
• She then takes Jacob to the Source and makes him ageless like her. After awakening and discovering the ruined work and village, the brother, distraught, kills their mother. Jacob fights with him and takes him to the Source, throwing him headfirst into the water, where his lifeless body floats into the Source, vanishing. Moments later, a pillar of smoke shoots out of the cave. Jacob discovers his brother's body deep in the jungle, and places it next to his mother's in a cave. The two will become the skeletons known as Adam and Eve found by Jack, Kate, Locke and Charlie some centuries later. ("House of the Rising Sun"), ("Across the Sea")

Either earlier or later than Jacob's birth

• The Temple, its underground complex, the surrounding wall, and the Tunnels are completed.
• The Man in Black's bench is made.

Most likely later events

• Multiple wells are excavated about the Island in search of the cause for strong magnetic phenomena or the Source, possibly including re-excavation at Jacob's brother's original site. Most likely this occured between 13-30 years later than Jacob's birth, as consequence of Claudia's people discovering certain places on the Island where metal behave strangely, and there was no re-excavation, but rather it was covered by Mother and found by the DHARMA Initiative. ("Because You Left")
• The Lighthouse is constructed and at least ultimately used by Jacob not far from the caves.

Later events

• Jacob commences efforts to identify and consider candidates to replace him, as his brother's spirit searches to kill him in order to escape the Island. He causes groups of people from parts of the outside world to come to and dwell for a while on the Island at different times, but strife among themselves or other problems, including potential involvement with the Man in Black/"Smoke Monster," lead to their dying there without descendants.
