Inscribed at top in small, non-ornamental hand: “Florius De Arte Luctandi.” (Can we say anything about this hand?) There is a small slash near the D which might be read as a comma, but I don’t think it is. I’ve noticed some people call the MS “Florius, de…” – this must be why.
At the same height, in the upper right corner, a numeral 1.
lower: 312, struck through
Large open blackletter “c c e” (as if practicing?), connected to pennanular device with curl at top—is this a logo of some sort?
Stamped, “Bibliotheque Nationale” in red circle
In brown ink, a six-pointed star with two swashes and a circle on a verticle line in the center, with E above the top point (? Could be something else, including S) and S at either side, even with the lower horizontal line.
“Supplt p. 674” in dark brown ink
