You should look at some Arabic calligraphy- there is a lot of artistic Arabic calligraphy where passages from the Quran, poetry, and other text are written beautifully as art.
BTW sorry for my rudeness, I find your project very cool and I love calligraphic type projects. I was so excited that I wanted to share something related to you. :-)
Heh no worries and thanks! I love Arabic/Islamic calligraphy too, but I've had to leave out all calligraphic forms of text art (calligrammes, micrography, carmina figurata, 17th century european calligraphic art, etc..) out of the archive to keep the scope of the project focused and clear. Otherwise it would take me another 8 years :)
However, there's some arabic letterpress stuff in the archive! https://garden-of-flowers.heikkilotvonen.com/?filters=arabic I hope to find more, especially the kufic style, but I haven't found many good sources for that kind of stuff yet.
