Nova: Secrets of the Parthenon

SINOSSI

Nova checks in to see how the multi-decade restoration of the Parthenon is going. They find the restorers dealing with a massive jigsaw puzzle with pieces that are only slightly different, many of which are broken or missing, and the remaining pieces were reassembled wrong by the last restoration team. Even modern methods are not up to the challenge of reconstructing the missing pieces with the necessary precision so it is necessary to rediscover the ancient methods.
