Jñānakośa · a treasury of the Indian knowledge systems
Where do the old books speak of metallurgy, of medicine, of the stars? A concordance of sources, concepts and attested passages — quoted verbatim, graded honestly.
The corpus
Each bar spans a work's scholarly dating range — width is uncertainty as much as duration, and many dates are contested (the data records the disputes rather than resolving them). Hatched bars are physical carriers: manuscripts, artifacts, inscriptions. Click any bar for details.
The taxonomy
Fifteen domains, from gaṇita to dhanurveda. Counts are sources / attestations tagged with a concept or anything narrower under it. Selecting a concept lights up its sources on the timeline above.
The evidence
Every attestation carries its verbatim text from a cited e-text, a translation with attribution, and a graded reading — explicit, inferred, metaphorical or disputed. Labeling proceeds in recorded batches; this is the beginning.
