A1 - Calvillo, Nelson A1 - Rabin, Ira T1 - Did the Original Scribes Write the Distigmai in Codex Vaticanus B of the Bible (Vat. gr. 1209)? N2 - The fourth-century Greek Bible manuscript Codex Vaticanus B (Vat. gr. 1209) contains pairs of horizontally aligned marginal dots known as distigmai, which correspond to textual variants in other manuscripts. The production of the distigmai has been variously dated to the 4th or 16th centuries. A fourth-century date would prove the early existence of hundreds of textual variants, many of which are otherwise only witnessed by later manuscripts. Near infrared microscope reflectography combined with micro-X-ray fluorescence spectroscopy proved that the distigmai, both those categorized as “apricot” (which are visually similar to the ink of the original main text) and “chocolate” (which are visually similar to the reinking of the main text) were written with ink(s) made from chemically purified vitriol, a process that only became standard in the 16th century. As a result, there is no reasonable chance that the distigmai were written in the fourth century. Horizontal lines that have been hypothesized to function as text-critical obeloi were written in the same ink as the original main text, which differs completely from that of the distigmai. In other words, the distigmai and horizontal lines tested were not produced during the same writing session and are separated by more than 1,000 years, making it impossible for them to have functioned as conjoining text-critical symbols in the 4th century.

To demonstrate the matrix tolerance of the method, several PFAS contaminated soil and sludge samples as well as selected consumer product samples (textiles, food contact paper and permanent baking sheet) were investigated. µ-XRF mapping allows for a unique element-specific visualisation at the sample surface and enables localisation of fluorine containing compounds to a depth of 1 µm. Manually selected fluorine rich spots were subsequently analysed via fluorine K-edge µ-XANES spectroscopy. To support spectral interpretation with respect to inorganic and organic chemical distribution and compound class determination, linear combination (LC) fitting was applied to all recorded µ-XANES spectra. Complementarily, solvent extracts of all samples were target-analysed via LC-MS/MS spectrometry. The detected PFAS sum values range from 20 to 1136 µg/kg dry weight (dw). All environmentally exposed samples revealed higher concentration of PFAS with a chain length >C8 (e.g. 580 µg/kg dw PFOS for Soil1), whereas the consumer product samples showed a more uniform distribution with regard to chain lengths from C4 to C8. Independent from quantified PFAS amounts via target analysis, µ-XRF mapping combined with µ-XANES spectroscopy was successfully applied to detect both point-specific concentration maxima and evenly distributed surface coatings of fluorinated organic contaminants in the corresponding samples.

T1 - The marginal notes of Tosefta MS Erfurt N2 - Manuscript Erfurt 12 of the Tosefta (now Berlin, Staatsbibliothek, Ms. or. fol. 1220) is one of three major textual witnesses of the Tosefta. This manuscript has over 80 marginal notes which have not merited scholarly attention. This article presents a comprehensive analysis of all the marginal notes, including an evaluation of their ink composition, a palaeographic assessment of the scripts, as well as a philological assessment of their contents. Combining these methodologies differentiates between the glosses of the scribe and those added by later hands and identifies their provenance, allowing us to trace the history of the manuscript via the emendations that took place in the scholarly communities in which the manuscript was studied. One of the important outcomes of the research is an early dating of the manuscript to eleventh-century Italy, overturning the scholarly view which dates the manuscript to twelfth-century Rhineland KW - Hebrew Manuscripts KW - Ink KW - NIR KW - XRF PY - 2025 DO - https://doi.org/10.3828/jjs.2025.76.2.272 SN - 0022-2097 VL - 76 IS - 2 SP - 272 EP - 300 AN - OPUS4-64770 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - JOUR A1 - Bonnerot, Olivier A1 - Del Mastro, G.

A1 - Rabin, Ira T1 - XRF ink Analysis of some Herculaneum papyri N2 - Recent research has suggested that some of the inks used in Herculaneum papyri do not consist of pure carbon. Starting from this finding, in June 2018 a preliminary campaign of analysis by means of X-Ray fluorescence (XRF) of external portions removed mechanically from their original rolls in the eighteenth century (the so-called scorze) took place at the Biblioteca Nazionale at Naples. Also in this case, the aim of the survey was to investigate the ink composition in order to detect possible traces of metal. This article sums up the results of this survey.
