Years ago I drove down to Austin to see the original scroll of Kerouac’s On the Road at UT’s Harry Ransom Center. Among the Center’s permanent collection is the Niepce Heliograph, a precursor to the daguerreotype, and the earliest surviving example of the origins of photography. The poets I know here will appreciate that heliograph translates as “sun writing”. https://www.hrc.utexas.edu/niepce-heliograph/
