XRF (Elio: 40kV, 80 µA, spot measurements of 120s each) and reflectography (DinoLite: x50 magnification, vis, NIR and UV light) analysis of inks from Milan, Ambrosian Library Ms Ambr. D 54 sup. (f. 2).
Ambr. D 54 is a paper manuscript containing mainly Aristotelian logic: the Isagoge, the Categories, the De interpretatione, the First Analytics, and the beginning of the Second Analytics I, together with scholia, diagrams, and exegetical treatises (Ioannes Philoponos and Leon Magentenos) that comment on them. Most of the folios appear to have been written by the same scribe, the otherwise unknown Alexios Solymas, who wrote a subscription on f. 203r on July 15th, 1272. The folios 1 and 2 were not written by Solymas and they are much later additions of disparate origin. Folio 1v contains a letter and can be dated on palaeographical basis to the fourteenth century. Folio 2 was written by Sylvester Syropoulos in the 1420s.
