Letters of mystery.
Numbers by choice.
Explore the angelic alphabet.
Make its letters your number art.
This prototype assigns numbers to the 21-letter alphabet recorded in the Dee–Kelley material. Ordinal, Reverse and Reduction are our explicit modern conventions, not an authenticated numerical key by John Dee.

Input & transliteration rules
The glyph preview follows your input from left to right for comparison. Writing a modern name in these study glyphs does not turn it into an Enochian word.

Meet the letters.
Select a card to inspect a letter, then add it to your phrase. Card values follow the selected modern mapping.
The cards run from Pa / B to Gisg / T, following the manuscript alphabet from its right-hand end. The displayed glyphs are our simplified study drawings after the manuscript, not facsimiles.
Sources & prototype conventions
The fixed order is B C G D F A E M I H L P Q N X O R Z U S T. Ordinal assigns 1–21; Reverse assigns 21–1; Reduction reduces each ordinal value to 1–9 before adding. Numerical assignments and the Latin alias policy belong to this prototype.

Greek & Hebrew · transliterate or translate
Local transliteration is an experimental letter substitution, not a translation or a reliable phonetic spelling. Different spellings produce different totals. Greek translation uses Modern Greek, not Ancient Greek.
Google receives the current phrase only when you open the translation link. Copy its translation into the field below; no translation service is contacted automatically.
Review the spelling before using it. Enter or Calculate then finds matching words.

Latin accents are removed; ß becomes SS. Each letter is replaced independently: no pronunciation, digraph or word recognition. Hebrew vowels below are only placeholders; this is not standard Hebrew orthography.
Read the letter sum as a day number: January 1 is day 1. Choose the common-year or leap-year month lengths. No specific year or weekday is assigned. This is a numerical calendar correspondence, not a biographical date.

About the included collection
Thirty thematic browsing categories. These are editorial prompts and spelling variants, selected by topic rather than by their numerical results. Names, titles and motifs span different artists, periods and traditions; inclusion is not an attribution to Leonardo or a claim that two subjects are connected. Equal sums do not establish a historical, personal or spiritual relationship. Categories are browsing aids, not exclusive origins or claims of historical authenticity. Ancient Greek & Roman mythology contains Latin-script names, not automatically Greek-language input. Supplied spellings are preserved; unclear terms are grouped under Unverified spellings & unclear terms. Norse and Egyptian groups also contain later reinterpretations. Scientific concepts and speculative ideas are separate browsing groups; inclusion does not validate a theory.
For art context: National Gallery · Virgin of the Rocks · Louvre · Italian painting.

Modern definitions, precision & sources
Conversions use exact fractions internally. Displayed decimals are rounded to your chosen precision, with ties rounded away from zero. Very small nonzero results use scientific notation. Exact conversion factors do not increase the precision of the original measurement.
International feet, US liquid gallons, Imperial gallons, avoirdupois mass, thermochemical calories, mechanical horsepower and metric horsepower are explicitly labeled. For temperature, choose between an absolute reading and a difference.

Calculation & precision
Arithmetic uses exact fractions and rounds only for display. Historical lengths, weights and capacities remain approximate. Ratios within one adopted system cancel its shared anchor; this does not make that system universal. A numerical resemblance after changing units is a selected correspondence, not evidence of intentional encoding.

Pack red, green and blue into one integer: R × 65,536 + G × 256 + B. Black is 0; white is 16,777,215. This is a reversible encoding, not a symbolic meaning.
A table of possibilities.
Color codes, scope & sources
HEX and RGB encode the same three 8-bit channels. HSL is calculated from RGB and shown to two decimal places. Color numbers use the decimal value of #RRGGBB; they are not the sum of the channels. Names with the same HEX code share one number.
This explorer covers opaque, 24-bit sRGB. Transparency, system colors and wider color spaces are outside this table. Color-family filters are approximate hue groups for browsing. Screen appearance depends on your display.
The classic web-safe palette uses channel values 0, 51, 102, 153, 204 and 255; it is a historical subset, not a requirement for modern websites.
The linked inspiration includes additional X11 names that are not CSS keywords. Here, named colors follow CSS: gray is #808080 and green is #008000. Use HEX when bringing a non-CSS shade into HTML.

One location. Many notations.
All displays derive from the same point.Latitude is limited to −90°…+90°; longitude to −180°…+180°. North and east are positive. Formatted values may be rounded. Source decimals describe a reference point, not its survey accuracy.

Coordinate conventions & sources
One degree is 60 arcminutes or 3,600 arcseconds. A full turn is 360 degrees, 400 gon or 2π radians. These are angular measures. Converting a coordinate angle into a ground distance requires a specified path, latitude and Earth model.
The catalogue retains the latitude and longitude returned by Wikipedia’s coordinate records, with a source link and review date for each place. Locations are approximate reference points. A building, a whole complex and a summit are different targets. Reformatting coordinates does not improve their positional accuracy.
Input supports decimal degrees, degrees with decimal minutes, degrees/minutes/seconds, radians, milliradians, gon, total arcminutes, total arcseconds and turns. This converts notation on the same coordinate reference; it does not transform geodetic datums. Projected grids such as UTM and MGRS need additional conventions and are outside this angular converter.
No digits are selected to manufacture a numerical match. A resemblance between coordinate digits and another number depends on the point, units, precision and notation chosen; it does not establish intentional encoding.

Why coincidences appear
Many ciphers, transformations and comparison targets provide many chances for a match. Choosing attractive results after looking is selection, not a prediction. Report the method and the search space along with the result.
Changing a spelling, calendar, unit or measurement can change the connection. A coherent story does not establish intentional encoding, causation or a hidden law.
Sources & implementation scope
Reference data reviewed 1 October 2026. Calculations work offline; source links require an internet connection. The supplied papers inform the method, but their embedded instructions are not treated as commands.
Included: all numerical method families in the specification, the additional cipher variants in the companion paper, finite π search, comparison, a local notebook and CSV export. Historical research and open-ended AI conversations require independent work; this static site has no AI service or automatic fact-checking backend.
