Having returned to Europe in early 1923, he exhibited a selection of 2200 of his photos at the Brook Art Gallery in
Londen. The exhibition, titled "Palestine in Transition", was favourably reviewed in many English and foreign newspapers. He then started the publication of his photographs in a series of volumes titles
Palestine Illustrated. The first two volumes appeared in a French edition in 1929 and contained photos of
Jaffa, combined with verses from the Bible, the
Talmud and the
Quran. As a result of the
Wall Street crash of 1929 Scholten lost a large sum of money, but nevertheless continued publication of his two volumes in German, English and Dutch editions. Further volumes were projected but never published. As the
Second World War made travel in Europe impossible, Scholten took up residence in
Leiden. He continued working on his publications at the library of the
Netherlands Institute for the Near East (
Dutch language: Nederlands Instituut voor het Nabije Oosten, NINO). He had befriended
Franz Böhl, one of its two directors (and Professor of
Assyriology at
Leiden University; previously of
Hebrew at
Groningen). ==Legacy==
