Passage: The Dutch East Indies government then commissioned Frans Carel Wilsen, a Dutch engineering official, who studied the monument and drew hundreds of relief sketches. Jan Frederik Gerrit Brumund was also appointed to make a detailed study of the monument, which was completed in 1859. The government intended to publish an article based on Brumund's study supplemented by Wilsen's drawings, but Brumund refused to cooperate. The government then commissioned another scholar, Conradus Leemans, who compiled a monograph based on Brumund's and Wilsen's sources. In 1873, the first monograph of the detailed study of Borobudur was published, followed by its French translation a year later. The first photograph of the monument was taken in 1872 by the Dutch-Flemish engraver Isidore van Kinsbergen.Appreciation of the site developed slowly, and it served for some time largely as a source of souvenirs and income for "souvenir hunters" and thieves. In 1882, the chief inspector of cultural artifacts recommended that Borobudur be entirely disassembled with the relocation of reliefs into museums due to the unstable condition of the monument. As a result, the government appointed Willem Pieter Groeneveldt, curator of the archaeological collection of the Batavian Society of Arts and Sciences, to undertake a thorough investigation of the site and to assess the actual condition of the complex; his report found that these fears were unjustified and recommended it be left intact.
