The druids did not write
verified
Caesar reports that the druids deliberately refused to commit their teaching to writing, requiring years of oral memorisation. Whatever else is uncertain, the absence of druidic texts is exactly what the ancient testimony predicts.
The consequence is severe and needs stating before anything else. There is no druidic corpus. Everything about druidic belief comes from either classical authors describing them from outside, often hostilely, or from medieval Irish and Welsh literature written centuries later by Christian scribes. Neither is a druidic source.
This makes Celtic material the mirror image of a tradition like Bahá’í, where the tradition documents its own numerical intent. Here there is no intent on record at all, and claims about “what the druids believed about three” are reconstructions presented as reports.
The Coligny calendar
verified
The Coligny calendar is a fragmentary bronze tablet found in France in 1897, generally dated to the 2nd century CE, inscribed in Gaulish using Latin letters. It is the single most substantial surviving document of Gaulish numerical practice, and it is a genuine artefact rather than a literary report.
verified
It lays out a five-year cycle of sixty-two months — sixty regular lunar months plus two intercalary months, not sixty-two plus two. Months are marked MAT or ANM, conventionally read as “good” and “not good”; MAT months have 30 days and ANM months 29.
The intercalation scheme is a real solution to the real problem set out in calendrical mathematics: reconciling lunar months with the solar year. It is independent evidence that Gaulish society was doing systematic calendrical arithmetic.
disputed
Detailed interpretations — the precise intercalation rule, the meaning of MAT/ANM, how the cycle was corrected over longer periods — remain debated, and the tablet is incomplete. Confident reconstructions should be read as proposals.
The Welsh triads
verified
The Trioedd Ynys Prydein (Triads of the Island of Britain) group traditional material in threes: three of this, three of that. They survive in medieval Welsh manuscripts and are a real and characteristic literary form. Irish legal and wisdom literature shows comparable triadic organisation.
exploratory
That the triadic form reflects a specifically druidic doctrine of three is a reasonable guess and no more. Triadic grouping is a widespread mnemonic device in oral literature — it appears in traditions with no Celtic connection whatever — and the manuscripts are Christian-era. As the number 3 hub sets out, threes recur because three is the smallest structured group, not because traditions share a source.
Ogham
verified
Ogham is an alphabet of twenty letters arranged in four groups of five (aicmí), attested in inscriptions mainly from Ireland and western Britain, principally 4th–6th century CE. The 4 × 5 structure is a plain fact about the script.
disputed
Ogham has no attested numeric values in the manner of Hebrew, Greek or Arabic letters. Systems assigning gematria-style values to ogham letters are modern. The medieval Auraicept na nÉces and the ogham tract material give letter names and associations — including tree names — but this is not a letter-number cipher.
The comparison with Gurmukhi in Sikh scripture is exact and instructive: a documented absence of a numerological system is itself a finding, and a useful one, because it shows that alphabets do not automatically acquire numerology.
What was invented recently
disputed
Much material presented as Celtic numerology — the “Celtic tree calendar” of thirteen months, systematic ogham divination, elaborate druidic number lore — derives from modern reconstruction. The thirteen-month tree calendar in particular traces to Robert Graves's The White Goddess (1948), a work of poetic scholarship whose historical claims are not accepted by Celticists.
This is graded disputed rather than dismissed because the material is real and worth understanding — as a twentieth-century phenomenon. The error is only in the dating. Modern Druidry is a genuine contemporary practice; it is not a survival, and its better representatives do not claim to be one.
The general principle is the one running through Claims That Fail: when the primary sources are thin, the space fills with reconstruction, and reconstruction is then read back as evidence for the thing it was reconstructed from.
