Baby books


Books from these early days are called incunabula. I love this word. Incunabulum is the singular form. It’s a Latin word that literally means ‘swaddling clothes,’ what they used to wrap newborn babies in. Think of a baby in a cradle or a crib. I think the swaddling clothes or the cradle are supposed to be the early printing business. The baby is the book. Book production in its infancy. Incunabula were the cradle of book-printing, like the Tigris-Euphrates valley is the cradle of Western Civilization, or Olduvai Gorge is the cradle of human evolution, or Massachusetts is the cradle of marshmallow and peanut butter sandwiches.

Folios and quartos



Back in the early days of printing and paper manufacturing, there weren’t standard sizes yet. On the other hand, they did have standard names for a book’s format:
A press sheet folded in half was called a folio. You get 2 leaves or 4 pages.
If you folded the press sheet again, you get a quarto—4 leaves or 8 pages. It’s half as big as a folio.
If you folded the press sheet one more time, you get an octavo—8 leaves or 16 pages. It’s one-fourth as big as a folio.


Of course you can keep folding, at least until you get so many pages the paper won’t bend anymore. These formats get called duodecimo, sextodecimo, octodecimo…

Any rags?

A rag collector in Paris late 1800s

In spite of Frederick’s decree, Europe’s papermakers simply got on with making paper. They added a twist to the recipe: rags. Rags means old cloth like towels, tablecloths, bedsheets, curtains, handkerchiefs, dresses, shirts, pants, socks, underwear, twine, even rope. In Europe, rag fiber meant linen or hemp. Buying old rags sprang up as a side business to support the papermaking business. Rag content in paper makes it pretty nice to draw and paint on. Here in the USA rag means cotton fiber. Rag paper is PH neutral—it contains very little or no acid so it doesn’t yellow over time. The European process was still pretty much the same one the Chinese used: you throw fibrous material into a vat of treated water and break down the fibers until you get a slurry.

The watermark found on many pages of Gutenberg’s bibles.

Most of Gutenberg’s bibles are printed on paper. He got his paper from a mill in northern Italy. The pages have a watermark—the logo of the mill is ever-so-slightly indented into the paper. You only see it when you hold the paper up to the light. How fitting is it that the watermark on the pages of the Gutenberg Bible is in the shape of an ox head? An ox head was the original shape of the first letter of our alphabet: aleph. https://johnmanders.wordpress.com/2021/01/11/canaanite-turquoise-miners-fool-around-during-lunch-break/

Paper or parchment?

Holy Roman Emperor Frederick II—’the Wonder of the World’ as his pals liked to call him

The invention of papermaking slowly—like a thousand years slowly—made its way to the Middle East and then Europe. In Spain and Italy, mills began cranking out paper in the 1100s. This paper was for writing on (of course, right? Printing wasn’t a thing yet).

Paper was considered not as good as parchment. There’s a sacred aspect to parchment. Parchment had been the preferred writing surface for religious and legal documents since the days when it replaced papyrus. Still, paper was less expensive than parchment, so customers started making the switch to paper.

The land-owning barons and earls who sold livestock to make parchment saw the new paper industry cutting in on their profits, so they sandbagged the demand for paper. In 1221 the Holy Roman Emperor Frederick II decreed that paper documents were invalid—which meant contracts written on paper weren’t legally binding. Lawyers, judges and government officials had to use the more expensive parchment just to keep their documents valid. It’s a sad fact that big business will always enlist cronies in government to squash their competition. Always.

Deckle and mold

The Chinese papermakers made wooden frames and stretched a mesh/screen across them—they were 2-piece flat strainers called a deckle and mold. Think of two screen windows—one has a screen in it, the other is an empty frame. They dipped the deckle and mold into the slurry and pulled them up horizontally. The water drained through the mesh. They removed the mold to leave a square of slurry on top of the mesh, which got transferred onto a piece of felt. Multiple pieces of felt and slurry were stacked together as a post and pressed to dry flat. When the whole post was finally dry, the slurry was paper that they could pull off the felt.



The Chinese papermakers improved on the recipe by adding bleach to brighten the paper’s appearance and finishing the paper’s surface with sizing (starch at first, then in the 1400s they switched to animal glue) to make it smoother.

PAPER!

Great galloping Agamemnon, we forgot paper! Why didn’t you guys say something?

Those monks hand-wrote their bibles on parchment or vellum, remember? Parchment isn’t cheap. It was Gutenberg’s mission to make bibles affordable, so most of them he printed on paper (just a few he printed on vellum) because paper was way less expensive.

Bamboo

Paper was another one of those Chinese inventions that came to the West along the Silk Road. They started making it around ad 100 (a guy named Ts’ai Lun is credited with paper’s invention). China’s first paper was made from bamboo, which is a reed—like papyrus in Egypt. Just like the Egyptians, they soaked the bamboo after splitting it into strips, then criss-crossed the softened strips into a sheet, pressed and dried it.



This kind of paper is not so good for printing. A printing surface needs to be perfectly smooth, and papyrus-style has ridges from the reed’s strips. To make high-quality paper—the good stuff—takes more work. Chinese papermakers figured out that you can soak the bamboo and other fibrous plants like flax in a vat of water and alkalei to break down their fibers more quickly. Alkalei is an acid you get from wood ash. They also beat the soaking bamboo (maybe like churning butter?) until the whole mess disintegrated into a slurry of plant fibers and water.
