These PTMs were constructed from images of all known remaining surfaces of the Antikythera Mechanism fragments housed in the National Archaeological Museum in Athens, Greece. The PTMs were constructed from images taken under varying lighting directions by Tom Malzbender, Dan Gelb and members of the Antikythera Mechanism Research Project during the week of September 12, 2005. Each PTM has a resolution of 3008 x 2000 and is >50Mb in size, so be patient during a download. These PTM files can be viewed interactively on the Windows or Linux platform by downloading the publically available PTM Viewer. Using this viewer, it is possible to transform the reflectance functions by the techniques of specular enhancement and diffuse gain to allow more detail to be seen.
