Psalm 83:4 turns up in my family's Passover liturgy, in a section devoted to memorializing the Holocaust and the Warsaw Ghetto Uprising.

However, wage inflation ensued and the calibre of book-thumbers fell. Eventually one of these "scholars" read his employer's books by dint of plowing them into a field.

How interesting that this technique was already in use in C.E. 800-1000.

"Illuminated . . ."

How long before some third-rate Elmer Gantry reads that word and starts crowing about the glowing miracle bible?

It's all coming together people!

Just sayin'.

(As a 'history of the bible' nerd, though, I have to say I'm doing a geeky dance of glee at the find).

*kicks Kip in the shins*

I can't remember where I read or heard that under these conditions the ink actually darkened the vellum with a chemical reaction. It may have been lifted off, but the vellum would still be marked where it was.

Hell, it's not as if portents of Armaggedon are so rare these days, anyhow. You just have to go stand outside until the heatstroke gets you, or a hurricane blows you away, or somebody blows something up, or a cable company proposes a frighteningly Mark Of The Beast-esque tiered Internet.

Or until a Senator proposes we switch to tube-based internets.

SFX: rumble of backhoe.
... FLASH! BANG!
... Awful silence.
Me (runs out of office): You idiot, you've just dug through a 10,000 volt cable and blacked out our whole block!
Him: rrr, duh, didn see anythin...
Me (tears hair): Sh*t, all our systems are going to be down for weeks!
Him: rrrr, like, sorry, duh, just doin what da boss told me...
Etc. Etc.

[For non-physicists here, the idiot survives because he's enclosed in his metal cab, though even the dumbest driver does notice that something has happened.]

Is the Joel Rosenberg of the interview the same person as the sf/f writer? I ask because I know that the writer is Jewish and Zionist. Has he gone over to the Christian fundies?

That's amazing. I wonder what the ink was made from.

However a quick visit to Google in search of iron gall ink recipes brings - tada! - more than you ever wanted to know about iron gall ink.

It's the Ink Corrosion Website. Absolutely amazing (from my point of view).

Back to the thread, this is pretty cool. I wonder if this means that backhoes can be used to dowse for things other than fibre optic cables?

They're really good for finding water pipes in city streets, especially those pipes that have inexplicably dropped off the blueprints...

The ink was based on oak galls, and it not only penetrates the vellum, it leaves chemical traces even if it's scraped off; you need a black light to see them, or sometimes, multi-spectrum imaging, to get them back. The real danger is exposure to light; that does cause the ink to fade.

I've posted about the bog psalter here.

They used Oak galls, both locally produced and imported from Aleppo (the best ones came from Allepo and they were as good as hard money). They were ground up and left to soak in rain water for a few days. The strained mixture was then mixed with what we'd call gum Arabic, made from the sap of an Acacia tree. Irish scribes used both copperas (ferrous sulphate) and lamp black (carbon). It sort of tans the vellum, thus leaving a mark even when the ink itself is gone.

The problem with this mss. is exposure to air will darken all the surface, and then, other things will, well, grow on it, and microbes and fungus will destroy it, and then the acid will destroy it as well.

Galls are distorted growth in the wood caused by a little bug. There can be galls on leaves (those are the ones I'm most familiar with), but I believe the galls they use for ink are in the wood itself.

If you've ever seen a branch that has a rounded lump on it (knobby growth?), that's probably a gall.

They are not acorns.

Then the catterpillar like thing bores a hole and leaves, sometimes as a fly sometimes as a caterpillar. You want to harvest the gall as soon after that as possible, because the tannin soon decays the gall, and if you do it before, the tannin hasn't accumulated; there's some sort of a tannin exchange biological process that involves the critter, though as yet I've found no good explanation of how/why the tannin that is naturally produced by the oak accumulates in the gall.

The ones from Aleppo seem to be higher in tannin, and it seems to be a product of the oak species, rather than the critter making the gall. They came to Ireland by way of France, and monastaries mostly bought with them with processed hides, ready for vellum manufacture, and with prepared ready-to-use vellum. As yet, we can't or haven't distinguished the kind of gall used based on chemical analyis of the ink, though we have done that with respect to the copper in the ink, and there's been some research into the DNA of the cow or sheep used in the vellum. We know, for instance that more than the Dun Cow was used for the Book of the Dun Cow.

I read someplace that the owner of the land in which the bog is located is mindful of what wonderful things can be found preserved in bogs, and asked the workers to be on the lookout.

I wonder if he was hoping for a bog mummy, and was a bit disappointed.

But bogs were used as cthonic ritual deposit areas, so lots of other lovely things are found there as well, like swords, arm rings, cauldrons, coins, infixes . . .

Weird and cool. In retrospect, it makes sense that you might be able to do that, but it had never occured to me that someone had gone and done it.

I believe that the insects which cause oak galls are usually wasps (very small wasps).

There's a lovely ring of threads here somewhere, along the lines of Psalms > Song of Solomon > sex > Kinsey > gall wasps > oak galls > ink > Irish monks tossing perfectly good Psalters into bogs > Psalms ... but I don't pretend to Mike Ford's talents.

There are apparently well over a thousand species of gall wasp. However (because Nature is never content with being simple) galls can also be formed by other insects. For example, the phylloxera aphid that devastated European vineyards in the 19th Century causes galls to form on grapevine roots and leaves.

The aphid galls are small; it's hard to remove them from the tree without crushing the gall. I suspect all the galls I've used were from wasps.

Apologies in advance, and though it'll probably be obvious in a verse or so, the tune is "So Where'd Those Darn Flowers Get To, Anyway?"

About a thousand years ago
In old Ireland
Brother Padric set him down
For praise on page
They had geese and they had sheep
All the things those places keep
But life is full of doubt;
Seems that the ink was out

Padric took a little trip
To the Eastern lands
If you want these things done right
You send a monk
In the East Aleppo lay
Tigris-and-Euphrates way
Out where there grew a tree
Stately as an oak can be.

Green and leafy stood the oak
As they tend to do
Giving shade and well bespoke
And it had wasps
Leaving eggs upon its leaves
Now a tree, it never grieves
Where we would be appalled
A tree is merely galled

Padric bought a bag of galls
At Aleppo fair
With a bit of haggling there
(That’s how it’s done)
Though the price was likely high
There’s a cost for what you buy,
The word wasps speak to men
Is universal ken

Pardon please while we digress
Momentarily
Centuries and seas away
To old I. U.
Alfred Kinsey watched the bugs
Meeting trees and cutting rugs
Down other paths it led
But let’s not lose the thread

Padric sits in northern light
With a tankard full
Tannin, gum, and vitriol
And his goose quill
All the Psalmists’ words come through,
David, Woody, Dylan too,
And before very long
He hears another song

It’s the Song of Songs, of course
(Though not Solomon’s)
Life is short but art is long
(Here’s to metaphor)
Watch her feet in sandal shoon
It’s an old familiar tune
Monks are not made of wood
Some things are understood.

Padric put his stylus down
Then what happened?
How did book come into bog?
We may never know;
Did the Norsemen make them flee,
Psaltery and battery?
Odd how we give events
A shot of violence

So the vellum went to sleep
Underneath the mire
We know the pH was right
Where light don’t shine
And when the reaction’s done
Ink and sheep become as one
It’s as we like to say,
Words do not fade away.

Now the years have come and gone
(It’s their habit to)
And the way earth turns around
Who would suppose
That a sharp-eyed bloke would be
Working with a JCB
Another page to turn
Another page to turn
