The Nicholas V. Artamonoff Collection includes 542 photographs taken in Istanbul and five archaeological sites in Western Turkey (Ephesus, Hierapolis, Laodicea on the Lycus, Pergamum, Priene) from 1935 to 1945. The high quality photographs are of great value as they show buildings, sites, and objects that no longer exist or are in a better state of preservation than today.
The Image Collections and Fieldwork Archives (ICFA) of Dumbarton Oaks holds the original negatives of these photographs. In 1980 all of the original Artamonoff negatives were copied to safety film negatives by ICFA for their preservation, and are housed in ICFA cold storage. This online exhibit has been created by Günder Varinlioğlu, former Byzantine Assistant Curator of ICFA, and Alyssa DesRochers, former ICFA intern. The project is ongoing; research continues and the site is a work in progress.
