 which aims at making these digitized images accessible worldwide.

Requirements and Aims

The project began with the glass negatives from the departments of the German Archaeological Institute at Athens, Istanbul and Cairo (Emagines1) in 2006. Negatives from Rome, Madrid, the headquarters in Berlin and the Eurasia-Department of the DAI were added during the second project phase in 2008 (Emagines2). These negatives mostly contain historical images of sculpture
Sculpture
Sculpture is three-dimensional artwork created by shaping or combining hard materials—typically stone such as marble—or metal, glass, or wood. Softer materials can also be used, such as clay, textiles, plastics, polymers and softer metals...

, topography and architecture, much of which no longer exists in its former condition. Furthermore, the negatives are severely threatened by physical decomposition and destruction due to environmental influences, natural catastrophes like earthquake

Workflow

To avoid exposing the fragile contents from the risks of long-distance transport, the images are being scanned in the departments of the German Archaeological Institute

The resulting documentation-complex is a centralised scientific of the DAI which can be accessed by web.

Data

84,298 (week 51 in 2009) glass negatives are currently available in Arachne. About 44,000 of these belong to the Emagines2 project. A fuzzy meta-search for the character string 'Emagines' results in about 48,000 hits in different categories, including the glass negatives. The glass negatives can be referenced through 84,298 records using image-navigation.
