In 166r-171v, the right column corresponds to BL Add 14661 72v (and to the Greek text in Khn XII 148-150) [identification made on the basis of the phrase ,they are drying in the second degree , legible in the gutter region, which belongs in the first of the passages devoted to lentils; a banal enough phrase, certainly, but one that I happened to have typed recently in working on the comparative material for the lentil section of unayns compilation]. Of these two leaves, I considered the first (166r-171v) to be, for our November work meeting: the text contained in the left column corresponds to a part of BL Add 14661 that is missing. I had forgotten that there was a lacuna in BL Add 14661 between fol. 72v and 73r (Wright 1872, p. 1187 [ the last (quire) being imperfect, owing to the loss of two leaves after fol. 72]; Merx 1885, p. 301 [Hier tritt ein Lcke im Text ein, der Fol. 73a mit weiter geht]). The left column of this leaf contains the first part of the Syriac text from that lacuna.

Spectral Imaging


Scholarly Study Dear Irene, Grigory, Matthias, and Siam,

Mike Toth and Bill Christens-Barry invited Jimmy and me to the BnF yesterday to observe their ultraviolet photography [sic] of a wandering leaf of the Syriac Galen Palimpsest that Grigory had tracked down last year.

They sent us the results this morning; one passage is particularly legible (shown here): its the first line of column A of the undertext of the leaf, and it reads, quite clearly:

The power/faculty of that elemental earth "

perhaps (but not certainly) followed in the second line by

which is

The first line is specific enough to be useful for a word search.

This particular sequence of words is not found in BL Add 14661, so the BnF leaf probably does not belong to Books VI-VIII of the Simples.

Given the theoretical nature of the topic, it is plausible that it comes from Books I-V.
