XRF (Elio: 40kV, 80 µA, spot measurements of 90s each) and  reflectography (DinoLite: x50 magnification, vis, NIR and UV light) analysis of inks from Vatican Library Ms Reg. Gr. 107.

The Organon manuscript Città del Vaticano, Biblioteca Apostolica Vaticana, Reg. Gr. 107 is a paper, composite manuscript consisting of two codicological units. The oldest unit was written around 1330-1350 by an anonymous scribe. The youngest unit was written around 1380-1390 by a team of scholars. The youngest unit (ff. 1-95) was produced to complement the defective oldest unit (ff. 97-487). Moreover, the scholars who made the youngest unit added a dense exegetical paracontent on the folios of the oldest unit. By the end of the 15th and beginning of the 16th century, Reg. Gr. 107 was read and annotated by three users, one of whom was identified as Demetrios Chalkondyles.
