The innumerable architectural members, once strewn about the Athenian Acropolis, are an important source for the reconstruction of the buildings on the Acropolis. Only the difficult sorting, registering, measuring and drawing, and the assignment of the fragments to their former context make this material truly valuable for scientific research. This work was done by Konstantinos Kissas, former member of the team working on the Acropolis and today Ephor of Antiquities in Corinth. His study presented here inlcudes more than 120 fragments documented in drawings, photographs and reconstructions (and more material is available on a CD that accompanies the volume). He offers important detailed observations that lead to new proposals for the reconstruction of the buildings of the Athenian Acropolis in the Archaic period, i. e. the century before the destruction of Athens by the Persians in 480 B.C. The material consists largely of unpublished architectural members, such as roof tiles of Naxian marble and sima- and metope-fragments from the so-called H-Building, which are studied in connection with architectural members of the ›Old Athena Temple‹.
