Ancient authors say of the druids that they studied the movement of the stars and measured time. For centuries these reports had no direct confirmation, until at the end of the nineteenth century the soil of Gaul gave back an exceptional object: a large bronze calendar written in the Gaulish language. This is the so-called Coligny calendar, the most extensive document we have on how the continental Celts organised the year.
The discovery
In November 1897, in a field near Coligny, in the French département of Ain, numerous bronze fragments came to light together with the remains of a bronze statue of a deity. Patiently reassembled, the pieces revealed a large engraved plate divided into columns and rows. Today the calendar is kept in Lyon, in the museum devoted to the Roman city of Lugdunum. It is usually dated to the Roman imperial period, around the second century AD.
One detail stands out at once: the language is Gaulish, but the alphabet is Latin. At a time when Gaul was already Romanised, someone felt the need to preserve in writing, and in a precious and durable metal, a reckoning of time that belonged to the native tradition.
How it is built
The calendar covers a five-year cycle. Each year is made up of twelve lunar months of 29 or 30 days, and at regular intervals an extra month is inserted to bring the lunar year back into line with the solar one. In all, the plate records sixty-two ordinary months and two intercalary months.
Next to each day a small hole has been drilled: most likely a peg was inserted to mark the current day, as on a wall calendar. Each month is divided into two halves, and the second is introduced by the word atenoux, which many scholars link to the idea of the «returning night» or the waning moon, although the exact meaning is debated.
The names of the months
The twelve ordinary months bear Gaulish names. Here they are in the order in which they appear:
- Samonios
- Dumannios
- Riuros
- Anagantios
- Ogronios
- Cutios
- Giamonios
- Simiuisonna
- Equos
- Elembiuos
- Edrinios
- Cantlos
Some names seem transparent: Samonios is often linked to a root meaning summer, Giamonios to one meaning winter. This has suggested a year divided into two great halves, a «light» one and a «dark» one. But Gaulish etymologies remain uncertain, because the language is known only in fragments.
MAT and ANM: favourable and unfavourable time
Each month is marked with an abbreviation: MAT or ANM. The first is commonly linked to a Gaulish word meaning «good, complete», the second to its negation. As a general rule, months of 30 days are MAT and those of 29 are ANM. The distinction therefore seems to have a technical value as well, tied to the length of the month, but the idea of «completed» and «incomplete» time carries a qualitative nuance.
| Abbreviation | Most common interpretation | Months |
|---|---|---|
| MAT | good, complete | usually of 30 days |
| ANM | not good, incomplete | usually of 29 days |
Individual days also carry abbreviated notes, such as D AMB, N INIS R, PRINNI LOUD, whose meaning is largely obscure. They probably indicated festivals, days suited or unsuited to certain activities, or ritual references that escape us today.
Samonios and Samhain
In the month of Samonios there is a note that has been read as referring to the «three nights of Samon-». Many scholars have compared it with the Irish festival of Samhain, which marked the beginning of the dark season. The link is suggestive and linguistically plausible, but it is not certain: we do not know for sure in which season Samonios fell in the Gaulish calendar, and centuries and great distances separate Roman Gaul from medieval Ireland.
Another fragment
The Coligny calendar is not alone. In a sanctuary near the lake of Villards-d'Héria, in the French Jura, fragments of a similar calendar have been found. Their existence suggests that instruments of this kind circulated in more than one place and were linked to sanctuaries, where the reckoning of sacred time was probably entrusted to specialists.
Why it matters
The calendar shows that the Gauls had a refined system for harmonising moon and sun, a problem every agricultural and religious civilisation has had to face. It also shows that time was not neutral: there were completed months and incomplete months, marked days and ordinary days. Time was quality as well as quantity.
For those who study the tradition, this is perhaps the most valuable lesson. Counting the days with care, recognising rhythms and thresholds, distinguishing the moments suited to beginnings from those suited to completion: this is a way of inhabiting time consciously, which Studio Esoterico Cornelio considers an essential part of all inner work.
In short
- The Coligny calendar, discovered in 1897, is a bronze plate in the Gaulish language and the Latin alphabet.
- It covers a five-year cycle of lunar months with two intercalary months to keep pace with the sun.
- The months are marked MAT or ANM, interpreted as «complete» and «incomplete».
- The link between Samonios and the Irish festival of Samhain is plausible but unproven.
- The document reveals a qualitative idea of sacred time, measured out in different days and months.
