Straif

sulphur

A reagent: the thing that changes what it touches and is not the point itself

Ogham glyphs are shown in Unicode, laid out left to right. On a standing stone the letters run bottom to top along the arris, so this row is a convenience rather than a facsimile.

A mineral in a tree alphabet

Straif means sulphur, and it is the least botanical name in an alphabet that is supposedly about trees. Not a plant, not an animal, not a body part: a mineral, and specifically a mineral used industrially.

The sound is uncertain. It is transliterated z, but Primitive Irish had no /z/, and the letter most likely stood for an archaic sibilant cluster — /st/, /sw/ or /ts/ — distinguishing it from the plain /s/ of Sail. Whatever it was, it merged away early, which is why the letter is rare on stone and why the manuscript tradition had to guess at its value.

The medieval gloss is blackthorn, draigen. The likeliest route is a pun on sensation: sulphur burns and stings chemically, blackthorn stings physically. It is not an etymology.

The dye-works

Tressam rúamnai is the strongest rúamna — a reddening, a dyeing, a staining. This is the kenning that anchors the letter, and it is about textile production.

Dyeing in early Ireland was serious, skilled and economically significant. Cloth was a store of value and a marker of rank; the law tracts regulate what colours and how many a person of a given status may wear. Getting a strong, fast colour into wool is not simple chemistry, and it depends on mordants — substances that fix the dye to the fibre so it does not wash or fade out.

Sulphur compounds belong to that world. So do iron salts, urine, alum and lye. A dyer's skill lay substantially in knowing which agent to use, in what quantity, and at what point in the process.

Which makes the second kenning follow naturally rather than mysteriously. Mórad rún is the increase or magnifying of rún — secrets. A dyer's recipes were the trade. Knowing how to get a deep red that held was a livelihood, and it was not shared. The letter names the reagent and then names the secrecy that surrounds knowing how to use it.

Saigid nél, seeking of clouds, is the physical observation: burning sulphur produces thick, choking, pale smoke that climbs. Anyone who has smelled it will recognise the phrase.

Not alchemy

It is tempting to read mórad rún as occult, and modern Ogham material frequently does, giving Straif meanings around magic, initiation and hidden power.

The kennings do not support that and the chronology makes it unlikely. Alchemy as a system reaches Western Europe through Arabic transmission from roughly the twelfth century; the Bríatharogaim are Old Irish, considerably earlier. Sulphur's role as one of the alchemical principles belongs to a tradition these composers had no access to.

What they did have access to was a workshop. Rún means a secret in the ordinary sense — something deliberately not told — and craft secrecy is amply documented without any esoteric framing. The dyer, the smith and the physician all held knowledge that was their income.

The honest reading is that Straif is about proprietary technical knowledge, which is a more interesting idea than mysticism and considerably better attested.

In reading

Straif is the agent of change rather than the change itself.

A mordant is not the colour. It is what makes the colour hold, and it is invisible in the finished cloth. In a spread this letter marks the catalyst — the person, condition or piece of information that is causing a transformation without being the transformation.

Its second face is secrecy that is functional rather than sinister. Somebody is not telling something, and their reason is that the knowledge is their position. That reads on questions about expertise, professional advantage, and information asymmetry, and it does not imply bad faith.

The smoke gives a third and cautionary note. Sulphur works and it is unpleasant to be near. Straif can mark a process that is producing the right result and is genuinely hard to be around while it runs.

Modern sets give blackthorn, with strife, fate and inevitability attached. That comes from the gloss, and the gloss came from a pun.

Questions to sit with

  • What is causing this change without being the change?
  • Who is not telling you something because the knowing is their position?
  • Is this process working and simply unpleasant to be near, or actually going wrong?

Frequently asked questions

Sulphur. It is the least botanical name in the alphabet — not a plant, animal or body part, but an industrially used mineral. Its kennings cover dyeing, guarded secrets and the smoke of burning.

Because tressam rúamnai, strongest reddening, points at textile production, which was skilled and economically serious. Cloth was a store of value and law tracts regulate what colours each rank may wear. Getting a fast colour into wool depends on mordants, and sulphur compounds belong to that class of fixing agents.

Almost certainly not. Alchemy reaches Western Europe through Arabic transmission from around the twelfth century, and the Bríatharogaim are considerably earlier. Rún means a secret in the ordinary sense, and craft secrecy is amply documented: a dyer's recipes were their livelihood and were not shared.

Uncertain. It is transliterated z, but Primitive Irish had no /z/, so the letter most likely stood for an archaic sibilant cluster such as /st/, /sw/ or /ts/, distinct from the plain /s/ of Sail. It merged away early, which is why the letter is rare on stone.

The agent of change rather than the change: a mordant is not the colour, it is what makes the colour hold, and it is invisible in the finished cloth. It also marks functional secrecy, where someone is not telling something because the knowledge is their position — which does not imply bad faith.
