1898 is pretty early in the technology of photography, maybe I didn't read carefully enough, but I would like to know what was used to take these photographs. They are very interesting and look better than I would expect for 1898!

As to the history of photography, when these were taken Fenton's [in]famous pictures of the Crimean War were already 50 years old. Sergey Prokudin-Gorsky colour pics of the Russian empire are of about the same early 20th century vintage.
The majority of the images depict Palestine (present day Israel and the West Bank) from 1898 to 1946.For reference this color photo was made about 10 years after these: https://www.loc.gov/resource/ppmsc.03959/
