Blast door map

Magazine map — Interpretation of the map from *Entertainment Weekly*

Inside the Swan are a series of blast doors which can seal parts of the bunker in a "lockdown" mode, the cause and purpose of which is currently unknown. During the lockdown, a series of black lights reveals a huge, hand-drawn map on the surface of one of the blast doors.

Chronology of the lockdown

Possibly unrelated: The countdown timer reaches zero, displaying hieroglyphics and initiating a mysterious mechanical process until apparently deactivated by pushing the button.
A garbled message by a female speaker, ending in a countdown to zero, is broadcast through the station's loudspeaker system.
The lights flicker.
The blast doors descend, sealing each compartment of the bunker.
When the countdown timer again reaches zero without completing the protocol, the lights go out entirely and a mechanical "revving up" sound can be heard.
A different set of ultraviolet 'black' lights that run vertically along the corners of the bunker illuminates what appears to be a color-coded map of the island on one of the blast doors.
Unconfirmed: The man known as Henry Gale claims to have entered the numbers into the computer.
The counter resets to 108. The power returns about 20 seconds later and the blast doors retract into the ceiling.
At approximately the same time as the lockdown, a large palette of DHARMA-branded provisions lands by parachute with a flashing beacon near the entrance to the bunker. A connection to the events of lockdown seems likely, but has not been confirmed.

The hidden map

Seems to be a crude map of the Island. The perimeter is octagonal and reminiscent of the DHARMA Initiative's logo.
Can only be viewed by black light. Written in unknown substance. Candidates include bleach, cat urine, and laundry detergent.
There are at least two types of notations on the map: Printed notes in English, which are very factual and seem informed; and Latin-language notes in a cursive hand, which are more observational and speculative—even philosophical.

Locations and geography

Shows the location of six stations (with a seventh scratched out), all "pointing" to the center of the island, represented on the map by a large question mark. Four of the bunkers have both graphics and text identifiers, apparently their respective names and logos; the two remaining have no titles, and their icons are difficult to decipher. Clockwise from bottom:

"THE SWAN" (bird): Notice what appears to be a detatched section of the bunker on the left, suggesting there is a part of the hatch that is blocked off that the Losties have not yet explored. Marked "3 of 6."
"THE FLAME" (fire): Notice the text "Alleged location of #4 The Flame" on the left side of the map
"THE STAFF" (caduceus): Official name uncertain
Scratched out: Notice the note to the left, something about the Incident
"THE ARROW" (arrow): Official name uncertain
Unknown
"THE PEARL" (no icon): Official name uncertain; may be called 'The Pearl' due to the notes to the right of the hatch

Numbers, dates, math, equations, science

Underneath "THE SWAN" it says: "3 of 6 (4, 8, 15, 16, 23, 42)"

Zoomed-in pic from EW.com, where you can see some of the numbers and dates
"108 00, 8, 15"
"01" (just below previous numbers, may be part of them)
√16 (which is 4), √64 (8) and √225 (15)
"4.08.00, 8.15.01, 01.06.03 - COMPLETE SHUTDOWN IN EFFECT".
- These seem to be dates using the month/day/year format.
- The last date is NOT "01.06.05", as it might appear to some. If you compare how the last digit is written to the way 3's and 5's are throughout the map, it is written like the 3's.
"x 4, y 8, z 15". Underneath it says "SUBTERRANEAN CONDUIT?"
4pi and the 1/r^2 are used to describe the surface area of a sphere not a coil.
Equations:
- The two differential equations shown on the map (B vector and H vector) are standard engineering/physics equations. B is magnetic flux density. Magnetic field strength (or intensity) is H.
- The magnetic field equation looks like a derivative of Biot-Savart, a formula describing what the field strength is on any given point for a coil or set of coils.
- The other equation might be Hubble's constant, which gives the rate of recession of distant astronomical objects per unit distance away, it was the main observation which led to the big bang theory and gives a rough estimate of the age of the universe.
- The other equation might not be Hubble's consant (partly because it's a vector and not a scalar constant!). Although if H is a magnetic field vector, it's not clear what the other constants could be, apart from k which could be wavenumber, so in that respect would fit cosmology more.
Valenzetti-related research has been made in The Swan. On 26 March 2006 someone "registered" the domains VALENZETTI.COM, THEVALENZETTIEQUATION.COM, ENZOVALENZETTI.COM and VALENZETTIEQUATION.COM (in the same column there is an ABC-SITES.COM too). The episode aired 3 days after. So it's evident that someone from the show registered them. If Valenzetti is really a mathematical theory or an equation, it probably has something to do with the "Numbers".
Valenzetti-related could also be valence TI-related research, where TI is titanium.

Theories and commentary

The map was apparently drawn by The Swan's previous inhabitants (like Desmond, Kelvin, and, judging from the mural, perhaps Thomas), begging the question: were they able to lower the blast doors themselves, or did they create the map only during the automated lockdown mode?
A strange thing however is, that the notes on the map sound more like planning notes (e.g. "not a suitable place for... not safe place for...") - maybe the map was not (or not entirely) made by previous inhabitants?
The message preceding the lockdown is hard to understand due to static, with one part possibly saying "begin protocol" and ends with a countdown to zero. Perhaps it was being broadcast by a passing aerial vehicle (silent enough not to be heard by the beach residents) as it delivered the fresh supplies.
- Possible other theories on what is being said in the message: "Please Proceed to Terminal". When Locke is adjusting the speaker, there's a spike of feedback. Right after this there's what sounds to be something in German, starting with "Zeit" which translates to "time". Upon closer examination, however, it sounds more like "17 minutes to lockdown" which is consistent with the "20 minutes to lockdown" heard while Locke is on the bike.
The blast door was not down all of the way since Locke's legs were caught underneath. There may be crucial information at the unseen top of the map.
The Blast Doors may come down because Dharma sent new supplies to the island.
The shape of the map seems to echo the shape of the Buddhist Dharma wheel.
Other part of the map says "Known resting place of Magnus Hanso / Black Rock"
- Magnus in Latin means: large, big, very, great, very much or important, etc.
- Magnus is also the name of a holy man who killed a dragon and ridded a land of evil beasts.
- Magnus may be a title of some sort (like Prof., Dr., Master).
- Probably means Hanso the Great
- There was a German philosopher and theologian named Albertus Magnus
- The Marvel Comics has a character named Magnus
The map indicates Cerberus activity. Cerberus was the three-headed dog who guarded Hades, the underworld of the ancient Greeks. He could be considered a...security system (which is what Danielle called the monster).
The words incident and activity are both found twice on the map, both times outside the octagon.
Ursus maritimus is the binomial name (or "Latin name") of The Polar Bear.
The existence of a "Dharmatel intranet" suggests the Michael-Walt IM session could have been real and not merely Michael's hallucination.
What is the purpose of drawing on the door in invisible inks/paints? Or on the door at all? Is this information being hidden from someone?
Why would someone detail this information on the blast door where it would be useless except for every once in a (seemingly distant) while when the doors shut unless they had a way to manually lower the doors whenever they wanted? This would make more sense as it would allow total privacy whenever the information was in plain view. It would make sense for there to be a means of lowering the doors manually, probably from within the room which is locked down.

Identification of known Island locations

The suitability/survivability of the midsection survivors' camp and an explanation for their apparent relative isolation can be gleaned from several notes near the "I am here" note:
- It's designated as a possible recreation area
- It's a low-priority zone for exploration
- There are no safe locations for Dharma infrastructure
- Large number of underground springs
- It also seems to be surrounded on the "north" and "northwest" by the Cerberus system, which could be inadvertently protecting the Oceanic survivors from the Others.
The location of the Black Rock (and apparently Magnus Hanso) and the identification of where "there be dragons" seems to roughly correspond with what Danielle called the Dark Territory
The station at six o'clock on the map is The Swan, which the Oceanic survivors refer to as "the Hatch."
The station at 10 o'clock on the map appears to be The Staff (a.k.a. Medical Station) with the caduceus logo, as visited by Kate, Danielle and Claire in the episode "Maternity Leave."

Quotes

If the "Even evil is afraid of the dark" translation of Malum non fidit atra is correct, it could correlate to the way the Others only take the "good ones". The phrase may also refer to to the Others' apparent fear or avoidance of the Smoke Monster/Cerberus, which would somewhat explain the relative safety the fuselage section survivors have experienced in comparison to that of the Tailies.
If the line is Mus uni non fidit antro, meaning "A mouse does not rely on just one hole," it is slightly reminiscent of what Sayid once said to Kate about Sawyer, "You go after him now and he'll give you nothing. But if you wait, a rat will always lead you to its hole."
Liberate te ex inferis would seem to be a direct nod to the redemption themes woven throughout the show.
Immediately before the map is revealed, Locke tells would-be Henry Gale, "We have to lift it up" (referencing the doors) which would seem to connect with Sursum corda. Desmond also told Jack when they met at the stadium, "You have to lift it up, brotha!" in reference to Jack's injured ankle.
Nil actum reputa si quid superest agendum is pretty much a fancy way of saying "It ain't over 'til it's over."

Hatches

Main article: Stations

There were originally seven stations, one of which (scratched out on the map) was destroyed (or per the map, "aborted") in "the incident."
The hatch names may correspond to the elements or constellations of Apollo e.g. Crater, Cygnus, Ophiucus, Orion, Phaethon, Sagitta
- There was a crater on Danielle's maps of the island
Two of the hatches might be underwater, underground, or at a higher elevation, based on the use of dashed lines to draw them. An underwater hatch, at the 4 o'clock position on the map, would be consistent with Sayid's discovery of the cable into the water in that area of the island.
Dr. Marvin Candle might be associated with Flame Station, given the link between candle and flame

  - "105" in Roman numerals, meaning "CV I" is actually "106," "CV II" is "107," etc., but what is the significance? CVIV is not a properly formatted Roman numeral. 109 is CIX not CVIV.
  - From rustina at TWOP: "For what it's worth, I don't believe that the CVII, CVIII, etc. are full Roman numerals, but rather part Roman numerals. We all know that Roman numerals can be written with or without the horizontal bars on top and underneath, yes? On the super-snazzy high-res map, there are horizontal bars included -- but only over/under the letters after the CV. To me, this is a definitive indicator that the C and the V are initials that stand for something, many possibilities of which have been mentioned in this thread, and the I, II, III, etc. are the numbers part. So, rather than it being 106, 107, 108, etc., I think it's CV6, CV7, CV8, and so on."
