Project Arc's New Jerusalem
Beyond the Cartesian Box
Modern architectural drawings naturally organize space through familiar Cartesian relationships—length, width, height, straight dimension lines, right angles, and box-like volumes. Those tools are useful, but Project Arc asks whether they can also become an inherited lens through which ancient biblical measurements are interpreted.
The New Jerusalem is Scripture’s climactic architectural vision: a measured city with twelve gates, twelve foundations, a jasper wall, pure gold like clear glass, the River of Life, the Tree of Life, and the throne of God and of the Lamb.
The traditional reconstruction is an enormous cube because Revelation 21:16 says the city lies “foursquare” and that its length, breadth, and height are equal. That interpretation may be correct. Project Arc asks whether it is the only geometry capable of satisfying the complete biblical description.
Preserve the biblical measurements. Examine the language, assembly, orientation, context, and recurring patterns of Scripture. Then let the geometry emerge.
Project Arc is an investigation, not a declaration.
Revelation 21:15-17
15 And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
16 And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.
17 And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
Measurements Plus Assembly
The Wilderness Tabernacle reinforces the same method. Exodus 26:7–13 gives eleven curtains with dimensions, joining instructions, doubling, remainder, and overhang. The architecture cannot be reconstructed from a single measurement. The assembly sequence matters.
Exodus 27:18 gives another fixed framework: 100 cubits long × 50 cubits broad. Project Arc preserves that 100 by 50 measurement exactly as written.
The measurements are biblical. The architecture must account for how those measurements work together.
The Seven Furnishings as Clues
The furnishings show that biblical architecture is more than exterior shape. Together they establish movement through sacred space: sacrifice, cleansing, bread, light, incense, approach, and divine presence.
The bronze altar supplies a direct foursquare control. The laver introduces water and cleansing. The table introduces bread. The lampstand introduces light. The incense altar marks movement toward the innermost sacred space.
Placement, orientation, light, water, function, and approach matter alongside measurement. Those themes return in Revelation.
From Noah to the City of God
Project Arc asks whether a larger architectural pattern runs through Scripture. Noah’s Ark preserves life through judgment. The Wilderness Tabernacle orders worship around divine presence. Solomon’s Temple develops sacred space around God’s dwelling. Ezekiel presents a measured sanctuary with water flowing outward. Revelation culminates in a city where God dwells directly with His people.
Together these structures provide recurring clues involving measurement, enclosure, sacred center, entrance, movement, light, water, and life. The Second Temple may prove to be an important linear exception in that progression, but that remains part of the investigation.
Foursquare: What Does Revelation Require?
Revelation 21:16 gives us two statements:
“The city lieth foursquare…”
and
“The length and the breadth and the height of it are equal.”
These are related, but they are not the same statement.
The traditional interpretation combines them into a cube.
But does foursquare itself mean cube?
Scripture says no.
The bronze altar was:
5 × 5 × 3 cubits
—Exodus 27:1
The incense altar was:
1 × 1 × 2 cubits
—Exodus 30:2
Both are called foursquare.
So:
Foursquare does not, by itself, mean equal length, breadth, and height.
Revelation gives those equal dimensions separately.
The real question is:
What geometry are those equal dimensions describing?
Four Directions
Revelation also organizes the city in four directions:
East — 3 gates
North — 3 gates
South — 3 gates
West — 3 gates
Four directions. Twelve gates.
Could foursquare describe this fourfold organization rather than requiring the entire city to be a conventional cube?
The Greek tetragōnos means foursquare, four-cornered, or quadrangular. Project Arc does not claim that it means circle, dome, or radius.
The question is narrower:
Does tetragōnos define the entire three-dimensional form, or could it describe fourfold order?
Four Quarters Around One Center?
Biblical sacred space is repeatedly ordered around the presence of God. Israel camped east, south, west, and north of the Tabernacle, with God's dwelling in the midst.
New Jerusalem again has four directional divisions, while God and the Lamb are its temple, the throne is the source of the River of Life, and God's glory is its light.
So we ask:
Could New Jerusalem be four ordered quarters around the divine center?
If so, could those quarters exist within a nonlinear geometry while preserving equal length, breadth, and height?
Project Arc does not change the measurements or redefine tetragōnos.
It asks:
Have we assumed that “foursquare” gives us the entire architecture when Scripture may be giving us its fourfold order?
The Wall and the Open Gates
Revelation 21:17 measures the wall at 144 cubits. Exactly what architectural dimension that number represents deserves careful study.
Revelation 21:21 says each gate is “of one pearl.” Scripture does not tell us that each gate looked like a gigantic spherical jewelry pearl; that familiar representation is an artistic interpretation.
Revelation 21:25 adds that the gates are never shut. The wall therefore does more than defend. It defines sacred boundary while permitting continual access:
boundary → gate → city → divine presence
From the Holy of Holies to the Holy City
1 Kings 6:20 describes Solomon’s Most Holy Place as 20 cubits × 20 cubits × 20 cubits. Revelation later describes the entire city with length = breadth = height.
This does not prove identical geometry, but the relationship deserves attention. Equal-dimensional sacred space once characterized the innermost sanctuary. In Revelation, equal-dimensional language expands to the scale of the City of God.
Then Revelation 21:22 says:
“And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.”
The progression becomes:
sacred chamber → sacred house → sacred city
God’s presence is no longer confined to an inner sanctuary.
Ezekiel to Revelation
Ezekiel 40–48 supplies another group of clues: measuring reed, gates, cardinal directions, sacred boundaries, tribes, and ordered territory.
Ezekiel 42:15–20 records 500 reeds on each side. Ezekiel 48:20 describes a sacred allotment of 25,000 × 25,000.
These measurements do not automatically establish radii, but they raise an architectural question:
How do equal measurements, cardinal directions, sacred boundaries, and divine presence relate?
Ezekiel 47 then describes water flowing outward from the sanctuary. Revelation 22:1 brings that pattern to its climax with “a pure river of water of life... proceeding out of the throne of God and of the Lamb.”
Now the architecture has movement:
THRONE → RIVER → TREE OF LIFE → NATIONS
God in the midst. Ordered space around His presence. Life flowing outward.
Measuring From Where?
Revelation 21:15 says the angel measures the city, the gates, and the wall. Verse 16 gives 12,000 furlongs.
The number is explicit. Its geometric application requires interpretation.
Where does that measurement begin and end? Extremity to extremity? Boundary to boundary? From a central reference toward an outer limit?
Project Arc should not turn the measurement into a radius simply because a nonlinear reconstruction needs one. But neither should a conventional wall-to-wall interpretation be treated as though Revelation supplies a modern Cartesian dimension line identifying both endpoints.
The measurement is biblical. Its geometric application must be demonstrated.

Linear to Nonlinear
The Measuring Reed & Radial Geometry
The Facts:
In Ezekiel 40–48, the heavenly guide uses a six-cubit measuring reed to chart the sacred sanctuary. Rather than measuring a perimeter from the outside in, the survey begins at the central threshold and extends outward in four cardinal directions (East, North, South, West). The outer wall measures 500 reeds on every side (Ezekiel 42:16–20), while the surrounding sacred allotment (Terumah) expands to 25,000 reeds (Ezekiel 48:20). In Hebrew measurement idiom, measuring from an interior holy focal point outward establishes a dimensional radius rather than a Cartesian baseline.
The "What Ifs":
What if Ezekiel’s 500-reed measurement was never intended to define the straight linear edge of a giant square box, but rather the radius of a radially proportioned sanctuary zone? What if the "foursquare" footprint of the outer complex represents a width-quartered geometry, extending equal 500-reed radii into four distinct quadrants? If the measuring reed projects equal structural distance from the altar at the absolute center, then the boundary becomes a balanced, concentric enclosure designed to safeguard the holy center from the profane—foreshadowing the multi-tiered, quartered layout of the New Jerusalem.
God at the Center
The New Jerusalem shows the final pattern of sacred space:
God is the center and source of everything.
Revelation says God and the Lamb are the Temple. His glory gives the city light, and the River of Life flows from His throne.
GOD
↓
GLORY
↓
LIGHT

LIFE

HEALING
The center is not just a location.
The center is the source.
Project Arc asks:
If God is the center, what geometry best reflects that truth?
God is central. Life flows outward. Order radiates from His presence.
The Biblical Pattern
Project Arc investigates whether Scripture reveals a consistent pattern of nonlinear architectural geometry—from Noah's Ark to the New Jerusalem—with the 2nd Temple as the notable linear exception.
The biblical measurements never change.
The question is whether those measurements have always been understood within their proper biblical context.
