Beyond the tree of texts: Building an empirical model of scribal variation through graph analysis of texts and stemmata

Stemmatology, or the reconstruction of the transmission history of texts, is a field that stands particularly to gain from digital methods. Many scholars already take stemmatic approaches that rely heavily on computational analysis of the collated text (e.g. Robinson and O’Hara 1996; Salemans 2000; Heikkilä 2005; Windram et al. 2008 among many others). Although there is great value in computationally assisted stemmatology, providing as it does a reproducible result and allowing access to the relevant methodological process in related fields such as evolutionary biology, computational stemmatics is not without its critics. The current state-of-the-art effectively forces scholars to choose between a preconceived judgment of the significance of textual differences (the Lachmannian or neo-Lachmannian approach, and the weighted phylogenetic approach) or to make no judgment at all (the unweighted phylogenetic approach). Some basis for judgment of the significance of variation is sorely needed for medieval text criticism in particular. By this, we mean that there is a need for a statistical empirical profile of the text-genealogical significance of the different sorts of variation in different sorts of medieval texts. The rules that apply to copies of Greek and Latin classics may not apply to copies of medieval Dutch story collections; the practices of copying authoritative texts such as the Bible will most likely have been different from the practices of copying the Lives of local saints and other commonly adapted texts. It is nevertheless imperative that we have a consistent, flexible, and analytically tractable model for capturing these phenomena of transmission. In this article, we present a computational model that captures most of the phenomena of text variation, and a method for analysis of one or more stemma hypotheses against the variation model. We apply this method to three ‘artificial traditions’ (i.e. texts copied under laboratory conditions by scholars to study the properties of text variation) and four genuine medieval traditions whose transmission history is known or deduced in varying degrees. Although our findings are necessarily limited by the small number of texts at our disposal, we demonstrate here some of the wide variety of calculations that can be made using our model. Certain of our results call sharply into question the utility of excluding ‘trivial’ variation such as orthographic and spelling changes from stemmatic analysis.

The Encyclopedia of the Medieval Chronicle brings together the latest research in chronicle studies from a variety of disciplines and scholarly traditions. Chronicles are the history books written and read in educated circles throughout Europe and the Middle East in the Middle Ages. For the modern reader, they are important as sources for the history they tell, but equally they open windows on the preoccupations and self-perceptions of those who tell it. Interest in chronicles has grown steadily in recent decades, and the foundation of a Medieval Chronicle Society in 1999 is indicative of this. Indeed, in many ways the Encyclopedia has been inspired by the emergence of this Society as a focus of the interdisciplinary chronicle community. The Encyclopedia fills an important gap especially for historians, art historians and literary scholars. It is the first reference work on medieval chronicles to attempt this kind of coverage of works from Europe, North Africa and the Middle East over a period of twelve centuries. 2564 entries and 65 illustrations describe individual anonymous chronicles or the historical oeuvre of particular chroniclers, covering the widest possible selection of works written in Latin, English, French, Spanish, German, Dutch, Norse, Irish, Hebrew, Arabic, Greek, Syriac, Church Slavonic and other languages. Leading articles give overviews of genres and historiographical traditions, and thematic entries cover particular features of medieval chronicles and such general issues as authorship and patronage, as well as questions of art history. Textual transmission is emphasized, and a comprehensive manuscript index makes a useful contribution to the codicology of chronicles.
