kennethreitz ce93f429a2 Add Knowledge: the vault's reference shelf, crosslinked across the site
Publish the Obsidian vault's Knowledge folder as /knowledge (881 notes,
67 folders), with a Knowledge item in the nav and footer.

- scripts/import_knowledge.py regenerates data/knowledge from the vault:
  slugged paths, folder notes as index pages, wikilinks resolved to site
  links (or plain text), callouts, highlights, and Dataview tables
  rendered statically. Personal notes are withheld via an exclusion
  list plus a privacy guard.
- tuftecms/core/knowledge.py builds a concept index from note titles and
  aliases. First mentions on ordinary pages link to their Knowledge note
  (capped, never in headings, code, links, or sidenotes); Knowledge pages
  list related notes and where they're mentioned across the site; other
  pages get a Related Knowledge block.
- Knowledge URLs join sitemap.xml (so the sweep test covers them), never
  displace existing legacy slugs, list alphabetically, and mermaid
  diagrams render client-side only on pages that have them.

# Theia
**Domain**: Sight, and the shining light of the clear sky
**Symbol**: The radiant aether, the glint of gold and gems, the seeing eye
**Roman Equivalent**: Theia
---
## Overview
Theia is the Titaness of sight and of the shining light of the sky — the brightness of the clear upper air by which the eye sees and the gleam by which precious things shine. Daughter of [Gaia](/knowledge/mythology/greek-mythology/gaia) and [Uranus](/knowledge/mythology/greek-mythology/uranus), she was called Euryphaessa, "the wide-shining," and the Greeks held that it was her light which gave gold and silver and gems their glitter and their worth. She is light considered from the side of the seeing: not the object shone upon but the radiance that makes seeing possible, and by extension the power that gives value to what is bright and rare.
She took her brother [Hyperion](/knowledge/mythology/greek-mythology/hyperion), the Titan of heavenly light, as her husband, and their marriage is a union of illumination and vision — light and the eye that beholds it. From it came the three luminaries who order all of time. Theia herself keeps to the background of myth, a quiet radiance behind her more famous children, but the whole visible brightness of the world is, in the old reckoning, her gift: without her shining, there would be nothing to see and no seeing of it.

## Key Myths
**Mother of the lights.** By [Hyperion](/knowledge/mythology/greek-mythology/hyperion), Theia bore [Helios](/knowledge/mythology/greek-mythology/helios) the sun, [Selene](/knowledge/mythology/greek-mythology/selene) the moon, and [Eos](/knowledge/mythology/greek-mythology/eos) the dawn — the three great lights of the sky. The Homeric hymn names her as the mother from whom the sun and the shining moon are born, the "ox-eyed" and "wide-shining" one who gives the luminaries their brightness. She is the source, on the maternal side, of every light that crosses the heavens.
**The goddess who makes gold shine.** Pindar sang of Theia as the goddess "of many names" for whom men prize gold above all things — because it is her radiance reflected in it. In this she is the giver of worth itself: what we call precious is precious because it catches and returns her light. Her domain reaches from the sun in the sky down to the gleam of metal in the hand.
**The seeing behind the sight.** As the Titaness of sight, Theia was sometimes invoked as the power that grants the eye its ability to perceive at all — an older Greek notion held that vision was a light streaming outward from the eye to meet the light of the world, and Theia stood behind both. She is the meeting of the shining thing and the seeing eye, the condition under which anything appears.
