8033Re: [textualcriticism] Proposed method (sans Vulgate)
- Aug 1, 2013Tim,
I think your results are intriguing. I have one question for you though. It is my understanding that most of the manuscripts are Byz in nature. So by including all the variants, doesn't your methodology weight the results in favor of the Byz text? It struck me as particularly interesting that the conventional 'better' manuscripts are farther away in your rankings from the hypothetical original Rec-6-1 than Byz and the early versions. Or is one to interpret the rankings so that a greater distance indicates a better text?

It occurred to me that I should drop the Vulgate from the group representatives used to recover the initial text because it is known to be secondary.
Using PAM to divide the UBS4 data set for Mark into six groups identifies these medoids: B, Byz, it-ff-2, arm, vg, 205. Dropping vg and finding the most frequent reading across the five remaining medoids recovers the text labelled Rec-6-1 in this table:
MVA of the UBS4-Mark data matrix with Rec-6-1 added produces these CMDS and DC results:
The recovered text is located near Families 1 and 13 in the CMDS map and is in the same branch as Families 1 and 13 in the DC dendrogram.
The MSW plot suggests 5- and 10-way partitions. A 5-way partition puts Rec-6-1 in this group: W, Theta, f-1, f-13, 28, 205, 565, 700, syr-s, arm, geo. However, it does not fit well as indicated by a negative value of a statistic called the silhouette width. A 10-way partition places Rec-6-1 in this group: f-1, f-13, 28, 205, 700, syr-s, arm, geo. In this case the sil. width for Rec-6-1 is positive, indicating a better fit.
Ranking witnesses by distance from Rec-6-1 produces this list:
205 (0.120); f-1 (0.149); Lect (0.208); 597 (0.226); Byz (0.227); G (0.232); 1292 (0.235); 180 (0.239); 1243 (0.239); 1010 (0.246); 1006 (0.248); slav (0.248); 28 (0.256); 700 (0.256); E (0.256); 1505 (0.259); 157 (0.268); 1424 (0.270); H (0.270); 1241 (0.274); F (0.274); Sigma (0.286); vg (0.287); arm (0.290); A (0.291); geo (0.291); f-13 (0.299); 1071 (0.299); syr-h (0.302); it-q (0.318); 33 (0.322); it-l (0.324); syr-p (0.330); 565 (0.353); it-aur (0.360); Augustine (0.364*); N (0.370*); 1342 (0.371); syr-s (0.373*); 579 (0.379); Theta (0.398*); eth (0.408*); syr-pal (0.409*); it-f (0.411*); 892 (0.414*); cop-bo (0.434*); it-ff-2 (0.435*); C (0.438*); L (0.438*); it-i (0.447*); Delta (0.448*); W (0.452*); cop-sa (0.453*); 2427 (0.477*); it-c (0.491*); it-b (0.495*); UBS (0.496*); Psi (0.500*); it-r-1 (0.526*); B (0.558); Aleph (0.564); it-a (0.586); it-d (0.591); D (0.602); it-k (0.625)
So, when the Vulgate is dropped from medoids identified by a 6-way partition of the UBS4-Mark data set and a text is recovered by taking the most frequent reading of the remaining five medoids, CMDS, DC, PAM, and ranking results indicate that the recovered text is in the vicinity of Family 1.
