Timeline:Pre-crash

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

Very likely after Across the Sea[]

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.

"Lafleur"

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.
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.

13 years later[]

The shipwreck survivors have built a thriving community of yurts and go on hunting expeditions deep into the forest.
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.

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 is prevented from reaching the source by his mother, who kills Claudia's people and fills in his well.
Mother takes Jacob to the Source and makes him ageless like her.
Jacob's brother, in a fit of rage at mother's attack, kills her before himself being killed by Jacob - an act which creates the smoke monster. Jacob then lays the bodies of mother and brother to rest in the caves.

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 around the Island in search of the cause for strong magnetic phenomena - the Source - possibly including re-excavation at Jacob's brother's original site.
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 leads groups of people from parts of the outside world to the Island at different times, but strife among themselves or other problems, including potential involvement with this brother, lead to their death without descendants.
