Princeton University just updated a website on the expedition of the late 1950s/early 1960s to St. Catherine’s Monastery at Mt. Sinai, where there is a repository of the world’s oldest icons. This collection is unique in that it documents, in color and condition, all of the monastery’s icons after cleaning and restoration in the 1950s and 1960s. These photos have not been digitally altered, except for cropping and rotating. Princeton’s Visual Resource Center digitized and catalogued the collection of several thousand color images (5 × 7 inch color Ektachrome transparencies and 35mm slides) of icons in the Monastery of Saint Catherine made by the joint expeditions that you can view and download by clicking the link below.
