The eclipse predictor (or Saros dial) of the Antikythera mechanism provides a wealth of astronomical information and offers practically the only possibility for a close astronomical dating of the mechanism. We apply a series of constraints, in a sort of sieve of Eratosthenes, to sequentially eliminate possibilities for the epoch date. We find that the solar eclipse of month 13 of the Saros dial almost certainly belongs to solar Saros series 44. And the eclipse predictor would work best if the… 

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.

Babylonian solar theory on the Antikythera mechanism

This article analyzes the angular spacing of the degree marks on the zodiac scale of the Antikythera mechanism and demonstrates that over the entire preserved 88° of the zodiac, the marks are

Our current knowledge of the Antikythera Mechanism

The Antikythera Mechanism is the oldest known mechanical calculator. It was constructed around the second century bce and lost in a shipwreck very close to the small Greek island of Antikythera. The

The Calendar on the Antikythera Mechanism and the Corinthian Family of Calendars

Abstract:This article explores the evidence for the Corinthian family of calendars in light of the calendar recently discovered on the Metonic Spiral of the Antikythera Mechanism. It will be argued

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 Back Plate Inscription and eclipse scheme of the Antikythera Mechanism revisited

This paper presents a new edition of the Back Plate Inscription (BPI) of the Antikythera Mechanism, a series of descriptions of circumstances associated with eclipses indicated cyclically by the

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

The Draconic gearing of the Antikythera Mechanism: Assembling the Fragment D, its role and operation

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

Solar Anomaly and Planetary Displays in the Antikythera Mechanism

Recent scholarship has greatly improved our understanding of the structure and function of the Antikythera mechanism.1 One unresolved issue is whether the mechanism included a display of the

Calendars with Olympiad display and eclipse prediction on the Antikythera Mechanism

Though no month names on the Metonic calendar were previously known, all 12 months are identified, which are unexpectedly of Corinthian origin, and the cycles of human institutions with the celestial cycles embedded in the Mechanism’s gearwork are linked.

Eclipse Prediction on the Ancient Greek Astronomical Calculating Machine Known as the Antikythera Mechanism

Two arithmetical models are presented here that explain the complete eclipse prediction scheme and imply a surprisingly early epoch for the Antikythera Mechanism.

The ancient Greek art of spbairopoiia was devoted to the building of models of the universe such as celestial globes and annillary spheres. But it also included the construction of geared mechanisms

Astronomical Algorithms

This book intends to be a guide for the (professional or amateur) astronomer who wants to do calculations, although a few astronomy oriented mathematical techniques are dealt with, such as interpolation, fitting curves, and sorting data.
