(A) Navigation map of the Aegean sea, 17th century illuminated parchment, 58.8 × 39 cm2 (©INP, Ghyslain Vanneste). Inset: zoomed view of the gelatinized area. (B) NLO imaging of the gelatinized area with some fluorescent bundles (arrows) (mosaic, field of view 1300 × 1100 μm2, pixel size 0.8 μm). (C) Average intensity depth profile over the white square area in B and (D–F) zoomed NLO images at different depths (10, 20 and 28 μm deep).
