X-Ray Fluorescence and Reflectography Data from Hamburg, Staats- und Universitätsbibliothek Hamburg Carl von Ossietzky, P. graec. 184.I

XRF (Bruker M6 JetStream: 50kV, 600 µA, maps with 150-200 µm steps and 22-30 ms per pixel), infrared reflectography (Osiris Apollo infrared camera, 150 mm, f/5.6/f/45 lens, 1510 nm long-wave pass filter) and  reflectography (DinoLite AD4113T-I2V: x40 magnification, vis, NIR ~940 nm and UV ~395 nm light) analysis of inks from P. graec. 184 I from the Staats- und Universitätsbibliothek Hamburg Carl von Ossietzky.

P. graec. 184 I (P. Hamb. I 39, Tm 44371, Rom. Mil. Rec. 1.76_44-45) is a fragment of a 4,33 m long roll with receipts for faenarium (payments for hay) for Roman soldiers of the <em>ala veterana Gallica</em>. The inks are carbon-based, containing various amounts of copper (Cu). The results of the analysis were published in Bonnerot, Olivier, and Leah Mascia. “Scribes and Writing Practices in Egypt’s Ala Veterana Gallica: A Preliminary Study of Inks from a Military Roll.” In <em>2023 IMEKO TC-4 International Conference on Metrology for Archaeology and Cultural Heritage. Rom (Italy), October 19-21 2023</em>, 2:845–50. Rome (Italy): International Measurement Confederation (IMEKO), 2023. https://imeko.org/publications/tc4-Archaeo-2023/IMEKO-MetroArchaeo-2023-157.pdf
