Summary
Gearing layout proposed by Evans et al for planetary indication on the Antikythera mechanism.
This team propose individual dials placed around the main face of the mechanism, with simple gearing and markings on the respective dial faces showing such information as: rising, setting, reversing and so forth of said planet.
Gear trains are:
- Mars: 224/71 * 19/128 = 0.4683
- Jupiter: 224/86 * 45/128 = 0.9157
- Saturn: 224/53 * 24/105 = 0.966
- Mercury: 224/57 * 77/96 = 3.152
- Venus: 224/29 * 25/63 * 20/98 = 0.6255
The idea of planetary indication on the Antikythera mechanism is relatively hotly debated because no hard evidence has ever been found to prove once and for all if such a display existed and if it did how it was engineered.
This image is just a general arrangement of the gearing layout, in a similar style to the image on commons of the known mechanism. This image omits all of the known mechanism apart from a1 and b1 to show where in relation the proposed gears fit.
If more detailed information about the proposed dials and how one would read them is required then please read Evans, Carmen and Thorndike's article entitled "SOLAR ANOMALY AND PLANETARY DISPLAYS IN THE ANTIKYTHERA MECHANISM"
