Three layers of the record, stacked like strata. Ancient witnesses sit at the bottom as date ranges, translations in the middle, and modern scholarship on top. The ribbon over each layer shows its density through time. Switch to true time to see how compressed the ancient evidence is, or click an era to zoom in.

Ribbons are kernel density estimates, and each witness's weight is spread across its date range. Scholarship dots are nudged sideways where they would overlap, so hover for the exact year. They count only works cited in this corpus, which shows what this edition draws on, not the size of the field.
