The above is the translated blast door map from the Hatch. It was supposed to represent the Dharma history on the island. Part of the notations were in Latin. Like the Egyptian hieroglyph details, there was a great deal of time and effort put into this one piece of set decoration. But the whole Dharma story arc now seems irrelevant as the LOST saga creeps to its end.
What were the key mysteries contained on the blast door?
There are references to "incident of 1985." It is noted that multiple escape conduits blocked after the incident. We are not totally clear what was that incident.
There are references to abandoned stations, from the incident or "possible catastrophic malfunction of the Cerberus system." Smokey was called the Cerberus. This infers that the smoke monster may have been an integrated into Dharma's command systems.
There is also a notation: fatalities: 5.
There was an aborted station #7 of large number of underground springs "heavywater table." Heavy water was used as an early component of nuclear energy.
Then there are the comments or statements:
"Save yourself from hell."
"There are dragons here."
"A mouse does not rely on just one hole."
"I think we're on the same wavelength."
"Lift up your heart lift up your heart lift up your heart."
"Don't consider that anything has been done if anything is left to be done."
"The wrath of the gods may be great, but it certainly is slow."
"I think therefore I am depressed."
"Its a bad plan that can't be changed."
"The disease worsens with the treatment; the remedy is worse than the disease."
