In this work we analyze the dark shades which are evident on the ΑMRP X-ray positive Computed Tomographies and Radiographies of the Antikythera Mechanism ancient prototype. During 2000 years under the sea, the Mechanism bronze parts were totally corroded. The decreased X-ray absorption of the corroded bronze, allowed the CTs capture even in the thick large side of Fragment A. During the photometric analysis of the CTs, apart from corroded bronze, at least two other different (corroded) metal… Expand

Ancient machine tools for the construction of the Antikythera Mechanism parts
TLDR
These ancient machine tools can be considered as the progenitors of the Hellenistic period machine tools, which were used for the construction of the mechanical components of the Antikythera Mechanism. Expand

Conclusions from the Functional Reconstruction of the Antikythera Mechanism
TLDR
Two functional models of the Antikythera Mechanism were reconstructed and helped to understand how the Mechanism worked and provided answers to questions regarding the presence and the use of some parts. Expand
