Frisian runes
A few dozen small objects from the coastal Netherlands are the reason runologists write "Anglo-Frisian" rather than "Anglo-Saxon", and the reason nobody can say for certain which side of the North Sea invented the alphabet's defining feature.
The expanded runic alphabet of the North Sea coast is usually called the Anglo-Saxon futhorc, and that name is half right. The same characters, doing the same jobs, turn up on the other side of the water: in Frisia, in what is now the coastal Netherlands. That handful of objects matters out of all proportion to its size.
How many inscriptions are there?
This is the first thing to get straight, because the answer moves depending on who is counting and how strictly they define "Frisian".
| Edition | Inscriptions admitted |
|---|---|
| Arntz and Zeiss, the old corpus | Nine |
| Looijenga (2003) | Twenty-one predating the 9th century |
| Giliberto (2000) | Thirty-one |
There is no agreed size for the Frisian corpus. Any figure quoted without an edition attached has picked one and not said so; a range of nine to thirty-one is a large range on a corpus this small.
What survives
Small, portable, mostly 6th to 8th century: combs, coins, sword fittings, antler and bone pieces, and objects of yew. Nothing monumental. The finds come largely from the terpen, the man-made dwelling mounds of the coast, whose waterlogged soil preserves wood in the way the Bergen wharf does.
| Object | What it is | Why it matters |
|---|---|---|
| Arum sword | A miniature yew-wood sword, far too slight to be a weapon, reading edæboda | The best-known Frisian find, and an amulet or token rather than a model |
| Westeremden yew-stick | 41 characters over three lines, on yew | The longest Frisian runic text there is, and the object behind a disputed claim about the rune stan |
The part that actually matters
The futhorc's defining innovation is the three-way split of the inherited a-vowel: the old ansuz rune took the o-value and became os, and two new runes, ac and æsc, were created to cover what was left. That split is what turns a futhark into a futhorc, and it had to happen somewhere.
The older assumption was that it must have been Frisia, on the general principle that the Continent came first. That does not follow from the evidence. The runic finds are early on both sides of the North Sea, and the case for an English origin exported to Frisia is at least as good as the reverse.
The English side of that comparison rests on two 5th-century objects. The Caistor-by-Norwich astragalus is the oldest runic find in England, but its runes are the inherited twenty-four, so it says nothing about the innovations. The Undley bracteate does: its æsc rune, and probably its os, make it the earliest inscription that can be argued to be futhorc at all. Set the Frisian finds against those two and the dates overlap, which is exactly why the question stays open.
Which side of the North Sea devised os, ac and æsc has never been settled, and the runic evidence does not obviously favour either. This is why specialists write "Anglo-Frisian" for the innovations: the compound keeps the question open rather than answering it by naming.
How Frisian material is cited
Frisian inscriptions carry no Rundata signature. That is a fact about cataloguing, not a gap in the record: Rundata covers the Scandinavian tradition, and Frisian, English and Continental material is catalogued elsewhere. On this site, as in the literature, those objects are identified by name and findspot instead; see methodology.
A note on the language
Questions this guide answers
- What are Frisian runes?
- Runic inscriptions from the coastal Netherlands, mostly 6th to 8th century and mostly on small portable objects. They use the same expanded alphabet as Anglo-Saxon England, which is why the two are treated together as Anglo-Frisian.
- How many Frisian runic inscriptions are there?
- Between nine and thirty-one, depending on the edition. The old Arntz–Zeiss corpus admitted nine, Looijenga counts twenty-one predating the 9th century, and Giliberto reaches thirty-one.
- Are Frisian runes the same as Anglo-Saxon runes?
- Effectively yes as an alphabet: the same characters with the same values. They are treated as one tradition, called Anglo-Frisian, precisely because no one has established which side of the North Sea developed it first.
- What is the longest Frisian runic inscription?
- The Westeremden yew-stick, with 41 characters over three lines. Its reading is contested line by line, so translations of it should be treated with caution.
