Codices, atlases, scores and field guides gathered in one dark scholarly room.
Choose a reading room below. Each object opens directly where it belongs.
Codices for bound works. Atlases for systems. Scores for music. Field Guides for practice.
Reference books, conceptual codices and public reading artifacts.
Enter the codex room →
Formal relationships, crossings and active mathematical instruments.
Enter the atlas vault →
Durable score and tablature objects, including Mercury Steps, with legitimate crossings into Music.
Enter Scores & Tablature →
Reading instruments that explain a room without replacing it.
Enter the field room →Revision 13 is the public reading edition. Later working material is not silently folded into it; what opens here is the book as this edition actually stands.
Revision 43 is the current Concordance: a reference corpus that keeps mathematical construction, scientific status, technical doctrine, and fictional extension distinguishable.
The refined R9 edition lives in Stories. The Library shelves the same reading object and sends the reader directly to it.
How to See: follow transformations, distinguish an object from its representations, and test what survives. Read the Tablet here, then continue to Projection House to operate its mathematics.
Maps of formal relationships and system crossings. The Mercurial Mathematical Atlas is meant to be used, not merely consulted.
An interactive atlas for inspecting mathematical objects, invariants, transformations, and relationships across the Mercurial World. Each crossing points back to the room where the phenomenon lives.
An interactive register places Mercury through Neptune by mean heliocentric distance, then overlays the explicitly fictional pyramid/node network from the Mercurial narrative.
Scores and tablature live here as durable reading editions. Return to Music when you want the living work rather than the document.
The current score and tablature songbook is available here as the durable reading edition.
The final tab book is available here as the durable performance text.
The current score is available here for direct reading.
The Mercurial Rosette Codex is available here as the current tablature edition. Its document retains its own cover; the shelf remains text-first like the other scores.
The current tab book is available here as the performance text.
Companion reading objects: read the explanation here, then return to the room to operate the instrument.
The public companion includes an index, Projection 0, I–XI and Coda. It is readable in its own right and remains explicitly tied to Projection House.
Primary, official, or institutional links for people whose work is explicitly credited or used as a public intellectual, artistic, musical, or design lineage elsewhere in The Mercurial World.
Intellectual source for The Formal Edge thought instruments.
Sources for the Infinite Floor's aperiodic tiling, impossible-figure, and historical lineage.
Research lineage for the Perception Laboratory's attention, completion, framing, and belief lens.
Musical and instrument lineage for the selected Strandberg Plini Edition and Archetype: Plini X production references.
Documented lineage for Harmonic Cartography’s interval-permutation and scale-family studies. Holdsworth explicitly described writing out possible intervallic permutations and using basic mathematics to organize scales and chords; Cartography remains an original construction, not a transcription.
Musical lineage for structured recurrence, Guitar Craft / Guitar Circle practice, and the Fripp-related long-cycle abstraction used in the Synodic Engine.
Musical and instrument-design lineage for touch-style guitar, systematic technique, and improvisational practice.
Documented lineage for Harmonic Cartography’s geometric lens: augmented and diminished parental forms, matrix-like fretboard thinking, and structural navigation.
Research lineage for the Harmonic Labyrinth's spectral and psychoacoustic analysis station.
Named musical lineage in the Talia rhythm material.
Named source lineages for Mysterium Coniunctionis and its Glass Bead / formal-systems context.
Reference lineage attached to the Luna Eden Abode design study.
Scope: explicit public intellectual, artistic, musical, and design lineages. Ordinary theorem eponyms and historical names used only as mathematical vocabulary are not exhaustively catalogued here.
The Library accepts no responsibility for where these doors lead.
Hermes beyond the threshold.
Get lost on the fretboard: chords, scales, altered harmony, and alternate tunings.
Enter the fretboard ↗ JOYCE / ANNOTATED READINGBegin at page 3 and click the strange words and phrases to open glosses, etymologies, allusions, and possible readings.
Begin with riverrun ↗ FORMAL SYSTEMS / STRANGE LOOPSChapter-by-chapter explanations and small interactive machines for the ideas inside the braid.
Pull on the strange loop ↗ BLAKE / ILLUMINATED BOOKSBlake's poetry and images reunited as illuminated books, manuscripts, paintings, and engravings.
Open the illuminated book ↗ PUBLIC DOMAIN / WUNDERKAMMERA digital cabinet of strange histories, celestial diagrams, occult material, art, science, and forgotten things.
Open a random cabinet ↗ CHYMISTRY / ISAAC NEWTONWatch the reactions that made early modern matter look alive: transmutations, mineral vegetation, and the Tree of Diana.
Watch matter misbehave ↗ ASTRONOMY / REAL-TIME 3DRoam planets, moons, asteroids, and spacecraft through browser-based NASA data visualizations.
Leave Earth ↗ NUMBER THEORY / PATTERNSType a sequence of numbers and ask whether mathematics has met it before.
Ask the numbers ↗ MUSIC / SCORESHundreds of thousands of scores and recordings, waiting behind a very old-fashioned door.
Open the score ↗ PRIVATE AVIATION / ESCAPEBecause eventually even the Librarian may decide the correct answer is a Gulfstream.
Charter something unreasonable ↗ ROCK TAILORING / ATTIREThe reading room has a dress code only in the Librarian's imagination.
Dress accordingly ↗ MODENA / GRAND TOURINGBlack on black grand touring. If the Gulfstream seems excessive, there is always Modena.
Leave by road ↗These are external doors, not endorsements or required reading. They open in a new tab so the stacks remain where you left them.
