@dbellingradt It's a pity that the text is covered, but anyways it starts by saying something like "More reveals itself the often thought Most Holy Secret also in the shape of the human heart, then so [?] a 3 [pointing down], which means as much as Trinum [...] Unum [...]". I guess Unum and Trinum are the reason for the i and the 3 at the top, but I'm not able to understand the meaning of that variation of HOMO ("man" in Latin)

@dbellingradt BTW, it must be an Austrian text, because at the very top it says "Oesterreichisches Deo Gratias". And yes, @bob_zim is right: there are even two different "r"s in that Fraktur typeface

@dbellingradt Oops, I didn't realize you are a German native speaker and a historian specialized in books :-D

@dbellingradt
oh, and let me keep on guessing: in HOMO the H and the Os are barred so as to focus the reader's attention on the M, that is below the i and 3, i.e., below Unity and Trinity, and contains the intermediate 2 (which looks like a z), as in M is made up of 2 opposing 1s (maybe the 2 genders?)

@waltertross it is much better and more complex, have a look: https://bsky.app/profile/dbellingradt.bsky.social/post/3lsnjlpdars23

@dbellingradt
that's fascinating! So the z remains to be explained. I would make sure
a) there's no hint in the text, and
b) it cannot be a 2 in any of the typefaces used.
If so, only z and N remain, with z not a truly Latin letter, maybe the initial of some non-Latin name or word

@dbellingradt I see in BS that the answer has been given by Paul White! It's a 2, and the i is indeed (also) a 1. So:
1 over I[nitium]
2 over V[erbum caro factum]
3 over I[gnis]
