Manuscript Tradition Simulacrum

What The Tool Does

Every text that survived to the age of print came down through manuscript copying, and every manuscript copy introduced errors — omissions, misreadings, scribal corrections, interpolations. The tool analyses the surviving manuscripts of a work, identifies the relationships between them, and reconstructs the transmission tree: which copies were made from which, where common errors reveal common ancestors, and what the lost archetype — the closest approach to the author's original that the surviving evidence permits — most probably contained.

The practical output is a *stemma codicum*, a diagram of the manuscripts' genealogy, together with an edited text that reports the variants at every point of disagreement. Where the stemma permits, a confident reading is proposed; where two branches of the tradition preserve equally-weighted readings, both are reported; where the archetype itself is unrecoverable, the uncertainty is acknowledged and the editor's best judgement is given with its reasons.

Where The Method Comes From

Stemmatics as a modern scholarly method was systematised by Karl Lachmann in the first half of the nineteenth century, primarily through his editions of the New Testament (1831), Lucretius (1850), and medieval German texts. Lachmann's achievement was the insight that shared errors between manuscripts are the marker of common descent — two manuscripts that share an obviously wrong reading must have inherited it from a common ancestor rather than independently produced it. From that principle, the whole genealogy can be reconstructed.

Paul Maas codified the method in *Textkritik* (1927), still the single most rigorous short statement of the discipline. In the second half of the twentieth century, Bernard Cerquiglini's *Éloge de la variante* (1989) and the New Philology movement pushed back against the Lachmannian search for a single archetype, arguing that medieval textual culture was fundamentally variant and that the search for the original sometimes obscured what was most interesting about the tradition. More recent work, led by Peter Robinson and others, has applied computational phylogenetic methods borrowed from evolutionary biology to large manuscript traditions, producing stemmata for works with hundreds of surviving witnesses. The tool draws on all three: Lachmannian rigour where the tradition supports it, New Philological humility where variance is itself meaningful, and computational methods where the manuscript count requires them.

What It Can And Cannot Do

The tool constructs stemmata, identifies significant variants, distinguishes scribal errors from authorial revision, locates the most probable archetypal reading at each point of divergence, and reports the confidence with which each reading is proposed. It handles Greek and Latin classical traditions, medieval vernacular traditions, patristic literature, and scriptural texts in their original languages.

It cannot recover what the archetype cannot preserve. If a reading was lost before any surviving manuscript was copied — if every surviving witness inherited the same corruption — the archetype itself is wrong, and only conjectural emendation can propose a better reading. The tool distinguishes clearly between readings supported by the manuscript tradition and readings that require editorial conjecture.
