A study of urban texts in Jerusalem between 1858 and 1948. Looking comparatively at Arabic and Hebrew, in use on various artefacts in the urban environment: money, banners, graffiti, stone inscriptions, shopsigns and street names. I am describing a cultural change and its implications, as old ways of writing make room for new ones, in the troubled context of Palestine.


I am using a range of sources and disciplines to investigate and reach conclusions: photographic material, drawings and paintings of Jerusalem; memoirs, autobiographies, travellogues and novels that give me an account of how text was read and perceived; archival material of the British administration in Palestine between 1917-1948, to understand British perception of urban texts.
