[FR] Définition des modèles organisés de signes triples du calendrier de ColignyLe calendrier de Coligny fut découvert il y a plus d’un siècle, au cours duquel les modèles complexes, interconnectés, des divers termes disposés au long de ses mois et années ont été dans une large mesure définis, à l’exception des signes triples qui jusqu’à maintenant n’ont été définis qu’en partie. Les modèles suivis par les signes triples seront ici définis de manière plus précise, ainsi que les interactions avec plusieurs notations, y compris le cas spécial du Jour 21, le cas anormal des triades placées à la fin d’une quinzaine, et le terme EXO. Avec la définition du modèle qui gouverne l’année, le modèle organisé qui sous-tend la distribution des signes triples peut maintenant être finalisé avec certitude, au lieu de compléter le calendrier en restituant les jours inconnus par assemblage.
[EN] It is now over a century since the Coligny calendar was discovered, during which time the intricate, complex and interrelating patterns of the various terms that are layered over its months and years have to a large degree been defined, one exception being the triple marks which have so far only been defined in part. Here the patterns followed by the triple marks are further defined, along with the mark’s interactions with several related notations, including the special treatment of Day 21, the anomalous treatment of triplets that run over the end of a fortnight, and the EXO term. With the definition of the pattern that governs the years, the systematic pattern underlying the distribution of the triple marks can now be finalised with certainty, rather than filling in unknown days through conflation.

[FR] Le caractère lunaire et métonique du calendrier de ColignyDans cet article, l’auteur analyse comment les mois du calendrier de Coligny suivent de très près les lunaisons pendant les 62 mois des 5 années figurant sur la plaque de bronze, et, ce faisant, met en évidence la précision extraordinaire, au jour près, à chaque «extrémité» de la lunaison moyenne. Cela signifie que chaque mois du calendrier lunaire commence toujours au même point de la phase de la lune, et que ce calendrier peut rester synchronisé avec la lune indéfiniment. La forme globale du calendrier est déterminée ensuite par l’attribution de 29 jours au premier mois intercalaire, ce qui fait du calendrier un calendrier métonique tout au long de 4 cycles successifs de 5 ans ; cela montre aussi que, dans cet ensemble de 5 années, nous avons une partie complète, la seule nécessaire, du calendrier entier. Ce calendrier métonique pouvait aussi être intégré à une période de 30 ans, constituée de 6 cycles successifs de 5 ans, sans qu’il soit nécessaire de redéfinir le cycle de 5 ans.
[EN] This paper examines how closely the lunar calendar months of the Coligny calendar track the individual lunations over the 62 months of the 5-year bronze plaque, and in doing so, discovers an extraordinary precision to within a day either side of the average lunation. This means that each calendar month always starts at the same point in the lunar phase and the calendar can remain in sync with the moon indefinitely. The question of the overall shape of the calendar is further defined by assigning 29 days to Intercalary One, which then shows the calendar to be a Metonic calendar through four successive cycles of the 5-year base, and that in the one 5-year plaque we have the complete and only needed part of the entire calendar. This Metonic calendar could also be embedded as part of a larger 30-year age of 6 successive cycles of the 5-year base, again without the necessity of re-shaping the 5-year base cycle.
