# Mexica calendar glyph sources and licenses This manifest covers only the local `exhibition-715` Mexica module. All rendered glyph assets are SVG with transparent backgrounds. ## Tonalpohualli day signs The 20 local files in `mexica-calendar-glyphs-source/` are reproductions in a consistent Codex Laud / central-Mexican manuscript style. They are used without semantic redrawing; filenames were normalized for the application. | Local file | Wikimedia Commons source | Creator | License | |---|---|---|---| | `cipactli.svg` | [Cipatli.svg](https://commons.wikimedia.org/wiki/File:Cipatli.svg) | Katepanomegas | CC BY 3.0 | | `ehecatl.svg` | [Ehecatl.svg](https://commons.wikimedia.org/wiki/File:Ehecatl.svg) | Katepanomegas | CC BY 3.0 | | `calli.svg` | [Calli.svg](https://commons.wikimedia.org/wiki/File:Calli.svg) | Katepanomegas | CC BY 3.0 | | `cuetzpalin.svg` | [Cuetzpalin.svg](https://commons.wikimedia.org/wiki/File:Cuetzpalin.svg) | Katepanomegas | CC BY 3.0 | | `coatl.svg` | [Coatl.svg](https://commons.wikimedia.org/wiki/File:Coatl.svg) | Katepanomegas | CC BY 3.0 | | `miquiztli.svg` | [Miquiztli.svg](https://commons.wikimedia.org/wiki/File:Miquiztli.svg) | Katepanomegas | CC BY 3.0 | | `mazatl.svg` | [Mazatl2.svg](https://commons.wikimedia.org/wiki/File:Mazatl2.svg) | Katepanomegas | CC BY 3.0 | | `tochtli.svg` | [Totchli.svg](https://commons.wikimedia.org/wiki/File:Totchli.svg) | Katepanomegas | CC BY 3.0 | | `atl.svg` | [Atl.svg](https://commons.wikimedia.org/wiki/File:Atl.svg) | Katepanomegas | CC BY 3.0 | | `itzcuintli.svg` | [Itzcuintli.svg](https://commons.wikimedia.org/wiki/File:Itzcuintli.svg) | Katepanomegas | CC BY 3.0 | | `ozomahtli.svg` | [Ozomahtli.svg](https://commons.wikimedia.org/wiki/File:Ozomahtli.svg) | Katepanomegas | CC BY 3.0 | | `malinalli.svg` | [Malinalli.svg](https://commons.wikimedia.org/wiki/File:Malinalli.svg) | Katepanomegas | CC BY 3.0 | | `acatl.svg` | [Acatl.svg](https://commons.wikimedia.org/wiki/File:Acatl.svg) | Katepanomegas | CC BY 3.0 | | `ocelotl.svg` | [Ocelotl.svg](https://commons.wikimedia.org/wiki/File:Ocelotl.svg) | Katepanomegas | CC BY 3.0 | | `cuauhtli.svg` | [Cuauthli.svg](https://commons.wikimedia.org/wiki/File:Cuauthli.svg) | Katepanomegas | CC BY 3.0 | | `cozcacuauhtli.svg` | [Cozcuauhtli.svg](https://commons.wikimedia.org/wiki/File:Cozcuauhtli.svg) | Katepanomegas | CC BY 3.0 | | `ollin.svg` | [Ollin.svg](https://commons.wikimedia.org/wiki/File:Ollin.svg) | Katepanomegas | CC BY 3.0 | | `tecpatl.svg` | [Tecpatl.svg](https://commons.wikimedia.org/wiki/File:Tecpatl.svg) | Katepanomegas | CC BY 3.0 | | `quiahuitl.svg` | [Tlaloc2.svg](https://commons.wikimedia.org/wiki/File:Tlaloc2.svg) | Katepanomegas | CC BY 3.0 | | `xochitl.svg` | [Xochitl2.svg](https://commons.wikimedia.org/wiki/File:Xochitl2.svg) | Katepanomegas | CC BY 3.0 | The rain day sign is traditionally represented through features of the rain deity Tlaloc; the source file is therefore mapped to `quiahuitl.svg` in the local calendar vocabulary. ## Xiuhpohualli veintena signs The 19 unchanged JPEG references in `mexica-calendar-month-glyphs-source/` were created by Grae Bear, CC BY 3.0, and come from the Wikimedia Commons [Aztec months glyphs category](https://commons.wikimedia.org/wiki/Category:Aztec_months_glyphs). The matching SVGs were replaced on 2026-09-05 with **modern simplified manual curve redrawings after those references**. This is not a downloaded historical SVG set, a high-resolution scan, or a restoration of details missing from the small JPEG references. The main silhouettes and month mapping are retained; contours and spacing are cleaned for small display sizes. Cream/gold colors are a modern interface treatment, not claimed manuscript colors. The files contain ordinary SVG curves/shapes, no raster images, scanline runs, embedded fonts, blur filters, or external dependencies. Backgrounds are transparent. All 18 twenty-day periods and the five-day Nemontemi period retain their existing filenames and symbol IDs. Each SVG includes source and adaptation credits. The adaptations are distributed under CC BY 3.0. Rebuild staged copies with `.design/mexica-calendar-wheel/tools/build-month-curve-glyphs.py`. The older `vectorize_month_glyphs.py` produces the superseded scanline edition; it must not be used to regenerate this curve edition. | Local SVG | Grae Bear reference | |---|---| | `atlcahualo.svg` | [MetzliAtlca.jpg](https://commons.wikimedia.org/wiki/File:MetzliAtlca.jpg) | | `tlacaxipehualiztli.svg` | [MetzliTlaca.jpg](https://commons.wikimedia.org/wiki/File:MetzliTlaca.jpg) | | `tozoztontli.svg` | [MetzliToz.jpg](https://commons.wikimedia.org/wiki/File:MetzliToz.jpg) | | `huey-tozoztli.svg` | [MetzliToz2.jpg](https://commons.wikimedia.org/wiki/File:MetzliToz2.jpg) | | `toxcatl.svg` | [MeztliToxcatl.jpg](https://commons.wikimedia.org/wiki/File:MeztliToxcatl.jpg) | | `etzalcualiztli.svg` | [MeztliEtzal.jpg](https://commons.wikimedia.org/wiki/File:MeztliEtzal.jpg) | | `tecuilhuitontli.svg` | [MeztliTecu.jpg](https://commons.wikimedia.org/wiki/File:MeztliTecu.jpg) | | `huey-tecuilhuitl.svg` | [MeztliHTecu.jpg](https://commons.wikimedia.org/wiki/File:MeztliHTecu.jpg) | | `tlaxochimaco.svg` | [MeztliMicc.jpg](https://commons.wikimedia.org/wiki/File:MeztliMicc.jpg) | | `xocotl-huetzi.svg` | [MeztliMiccH.jpg](https://commons.wikimedia.org/wiki/File:MeztliMiccH.jpg) | | `ochpaniztli.svg` | [MeztliOch.jpg](https://commons.wikimedia.org/wiki/File:MeztliOch.jpg) | | `teotleco.svg` | [MeztliTeo.jpg](https://commons.wikimedia.org/wiki/File:MeztliTeo.jpg) | | `tepeilhuitl.svg` | [MeztliTep.jpg](https://commons.wikimedia.org/wiki/File:MeztliTep.jpg) | | `quecholli.svg` | [MeztliQue.jpg](https://commons.wikimedia.org/wiki/File:MeztliQue.jpg) | | `panquetzaliztli.svg` | [MeztliPanq.jpg](https://commons.wikimedia.org/wiki/File:MeztliPanq.jpg) | | `atemoztli.svg` | [MetzliAtem.jpg](https://commons.wikimedia.org/wiki/File:MetzliAtem.jpg) | | `tititl.svg` | [MeztliTitl.jpg](https://commons.wikimedia.org/wiki/File:MeztliTitl.jpg) | | `izcalli.svg` | [MeztliIzcalli.jpg](https://commons.wikimedia.org/wiki/File:MeztliIzcalli.jpg) | | `nemontemi.svg` | [MeztliNem.jpg](https://commons.wikimedia.org/wiki/File:MeztliNem.jpg) | ## Numerals - Units 1–19 are locally drawn as additive dots following documented Mexica unit notation. - The 20 flag sign uses [Mexica 20.svg](https://commons.wikimedia.org/wiki/File:Mexica_20.svg), created by Juan Miguel and released to the public domain. - The local display copy retains that source geometry and uses a rounded warm numeral stroke matching units 1–19, with a filtered dark separation outline behind that same path. No historical shape is filled or redrawn. - The notation reference used for the implementation is UNAM CCH's [Sistema de numeración posicional](https://portalacademico.cch.unam.mx/cibernetica1/sistemas-de-numeracion/sistema-de-numeracion-posicional). ## License texts - [Creative Commons Attribution 3.0](https://creativecommons.org/licenses/by/3.0/) - Public-domain status and any file-specific history remain documented on the linked Wikimedia Commons description pages.
