Sanatan knowledge was written down, taught in schools, argued over in commentaries, and carried away by people who came here to study. What happened afterwards is not in dispute: the knowledge kept travelling and the names of the people who produced it stopped being taught. This page puts those names back, one stream at a time.
0 of 31 streams answer all four — who, when, which text, on whose authority. The rest are being sourced at the source desk, where only a human may mark a chain verified.
Date range at the top, the people inside it, and under each person the books he actually wrote — each one mapped to the same category the courses use, so the history and the curriculum are one taxonomy, not two. The credit line is written as ours: we state it ourselves rather than wait to be given it, and it is only written where a Sanskrit work is actually named on the record.
