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… 

The Draconic gearing of the Antikythera Mechanism Assembling the Fragment D on the Antikythera Mechanism: Its role and operation

The unplaced Fragment D of the Antikythera Mechanism with unknown operation, was a mystery since the beginning of its discovery. The gear r1, which was detected on the Fragment radiographies by C.

The reconstruction of the Antikythera Mechanism Instruction Manual after a diligent study and analysis of the Back cover inscription (part-1)

The Inscriptions which were on the Back Cover of the Antikythera Mechanism were the User’s Manual of the Antikythera Mechanism. In the Back Cover Inscription Part-1 text, the Presentation, Position,

Renumbering of the Antikythera Mechanism Saros cells, resulting from the Saros spiral mechanical apokatastasis

After studying the design geometry of the Antikythera Mechanism Saros spiral, new critical geometrical/mechanical characteristics of the Back plate design were detected. The geometrical

Reconstructing the lost eclipse events of the Saros spiral applying the Draconic gearing on the Antikythera Mechanism. The impact of the gearing errors on the pointers position

We present new observations concerning the procedure for the reconstruction of the lost eclipse events engraved in the Saros spiral cells of the Antikythera Mechanism. For the reconstructed eclipse

The Initial Calibration Date of the Antikythera Mechanism after the Saros spiral mechanical Apokatastasis

This work analyzes the phase correlation of the three lunar cycles and the Saros/Exeligmos cycle, after the study of the chapter “About Exeligmos” in “Introduction to the Phenomena” by Geminus.

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.
