The historiographical eras, oldest at the top, read as a family tree rather than a
list — where one stance grows out of another, where it forks, and where a later voice answers or
breaks from what came before. Every node's name, dates, and description come straight from this
repo's own historiographies-of-astrology grammar; only the lines connecting them are
this page's own claim about lineage. Tap any era to read more, or open it as a grammar where one
exists in this repo. See also Lenses for the same planet read across
traditions, or all grammars for the full library.
grammars/historiographies-of-astrology/grammar.json — add or edit a view-*
item there and it appears here automatically, no code change needed. The parent→child lines are
a small hardcoded EDGES list in this page, because lineage is this page's own honest
simplification of a five-thousand-year practice, not a fact stored in the grammar itself.
Some eras here also have a full grammar in this repo you can open —
Ptolemy's Tetrabiblos, Alan Leo, Proctor's skeptical astrology, and the canonical Western
interpretation set — look for their Cards / Study / Tree links on the matching node.
