Welcome to the I Can't Sleep Podcast,
Where I help you drift off one fact at a time.
I'm your host Benjamin Boster,
And today's episode is about papyrus.
Papyrus is a material similar to thick paper that was used in ancient times as a writing material.
It was made from the piss of the papyrus plant.
Cyperus papyrus.
A wetland sedge.
Papyrus,
Plural papyri or papyruses,
Can also refer to a document written on sheets of such material,
Joined side by side,
And rolled up into a scroll,
An early form of a book.
Papyrus was first known to have been used in Egypt,
At least as far back as the first dynasty,
As the papyrus plant was once abundant across the Nile Delta.
It was also used throughout the Mediterranean region.
Apart from writing material,
Ancient Egyptians employed papyrus in the construction of other artifacts,
Such as reed boats,
Mats,
Rope,
Sandals,
And baskets.
Papyrus was first manufactured in Egypt as far back as the 3rd millennium BCE.
The earliest archaeological evidence of papyrus was excavated in 2012 and 2013 at Wadi al-Jarf,
An ancient Egyptian harbour located on the Red Sea coast.
These documents,
The Diary of Mirror,
Date from circa 2560 to 2550 BCE.
The papyrus rolls describe the last years of building the Great Pyramid of Giza.
For multiple millennia,
Papyrus was commonly rolled into scrolls as a form of storage.
However,
At some point late in its history,
Papyrus began being collected together in the form of codices,
Akin to the modern book.
This may have been mimicking the book form of codices created with parchment.
Early Christian writers soon adopted the codex form,
And in the Greco-Roman world it became common to cut sheets from papyrus rolls to form codices.
Codices were an improvement on the papyrus scroll,
As the papyrus was not pliable enough to fold without cracking.
And a long roll or scroll was required to create large volume text.
Papyrus had the advantage of being relatively cheap and easy to produce,
But it was fragile and susceptible to both moisture and excessive dryness.
Unless the papyrus was of perfect quality,
The writing surface was irregular and the range of media that could be used was also limited.
Papyrus was gradually overtaken in West Asia and Europe by a rival writing surface that rose in prominence known as parchment,
Which was made from animal skins.
By the beginning of the 4th century CE,
The most important books began to be manufactured in parchment,
And works worth preserving were transferred from papyrus to parchment.
Parchment had significant advantages over papyrus,
Including higher durability in moist climates and being more conducive to writing on both sides of the surface.
The main advantage of papyrus had been its cheaper raw material.
The papyrus plant is easy to cultivate in a suitable climate and produces more writing material than animal hides.
However,
As trade networks declined,
The availability of papyrus outside the range of the papyrus plan became limited,
And it thus lost its cost advantage.
Papyrus's last appearance in the Merovingian Chancery was with a document from 692 CE,
Though it was known in Gaul until the middle of the following century.
The latest certain dates for the use of papyrus in Europe are 1057 for a papal decree under Pope Victor II,
And 1087 for an Arabic document.
Its use in Egypt continued until it was replaced by a less expensive paper introduced by the Islamic world.
By the 12th century,
Parchment and paper were in use in the Byzantine Empire,
But papyrus was still an option.
Until the middle of the 19th century,
Only some isolated documents written on papyrus were known,
And museums simply showed them as curiosities.
They did not contain literary works.
The first modern discovery of papyri rolls was made at Herculaneum in 1752.
Until then,
The only papyri known had been a few surviving from medieval times.
Scholarly investigations began with the Dutch historian Caspar Jacob Christiaan Ruivens.
He wrote about the content of the Leiden Papyrus,
Published in 1830.
The first publication has been credited to the British scholar Charles Wycliffe Goodwin,
Who published for the Cambridge Antiquarian Society,
One of the papyri Graecae Magicae V,
Translated into English with commentary in 1853.
Papyrus was made in several qualities and prices.
Pliny the Elder and Isidore of Seville described six variations of papyrus that were sold in the Roman market of the day.
These were graded by quality based on how fine,
Firm,
White,
And smooth the writing surface was.
Grades range from the superfine Augustan,
Which was produced in sheets of 13 digits,
10 inches wide,
To the least expensive and most coarse,
Measuring 6 digits,
4 inches wide.
Materials deemed unusable for writing or less than six digits were considered commercial quality and were pasted edge to edge to be used only for wrapping.
The English word papyrus derives via Latin from Greek,
Papouros,
A loanword of unknown origin.
Greek has a second word for it,
Biblos,
Said to derive from the name of the Phoenician city of Byblos.
The Greek writer Theophrastus,
Who flourished during the 4th century BCE,
Uses papyrus when referring to the plant used as a foodstuff,
And byblos for the same plant when used for non-food products,
Such as cordage,
Basketry,
Or writing surfaces.
The more specific term biblos,
Which finds its way into English in such words as bibliography,
Bibliophile,
And bible,
Refers to the inner bark of the papyrus plant.
The virus is also the edamame of paper,
A similar substance.
In the Egyptian language,
Papyrus was called waj,
Chufi,
Or jet.
The word for the material papyrus is also used to designate documents written on sheets of it,
Often rolled up into scrolls.
The plural for such documents is papyri.
Historical papyri are given identifying names,
Generally the name of the discoverer,
First owner,
Or institution where they are kept,
And numbered,
Such as Papyrus Harris I.
Often an abbreviated form is used,
Such as P.
Harris I.
These documents provide important information on ancient writings.
They give us the only extant copy of Menander,
The Egyptian Book of the Dead.
Egyptian treatises on medicine and on surgery.
Egyptian mathematical treatises,
And Egyptian folktales.
When in the 18th century a library of ancient papyri was found in Herculaneum,
Ripples of expectation spread among the learned men of the time.
However,
Since these papyri were badly charred,
Their unscrolling and deciphering are still going on today.
Papyrus was made from the stem of the papyrus plant,
Cyperus papyrus.
The outer rind was first removed,
And the sticky,
Fibrous inner pith is cut lengthwise into thin strips,
About 40 cm long.
The strips were then placed side by side on a hard surface,
With their edges slightly overlapping.
And then another layer of strips is laid on top at right angles.
The strips may have been soaked in water long enough for decomposition to begin,
Perhaps increasing adhesion,
But this is not certain.
The two layers possibly were glued together.
While still moist,
The two layers were hammered together,
Mashing the layers into a single sheet.
The sheet was then dried under pressure.
After drying,
The sheet was polished with a rounded object,
Possibly a stone,
Seashell or round hardwood.
Sheets or melema could be cut to fit the obligatory size or glued together to create a longer roll.
The point where the malema are joined with glue is called the calyces.
A wooden stick would be attached to the last sheet in a roll,
Making it easier to handle.
To form the long strip scrolls required,
Several such sheets were united and placed so all the horizontal fibers,
Parallel with the roll's length,
Were on one side.
And all the vertical fibers on the other.
Normally,
Texts were first written on the recto,
The lines following the fibers,
Parallel to long edges of the scroll.
Secondarily,
Papyrus was often reused,
Riding across the fibers in the verso.
One source used for determining the method by which papyrus was created in antiquity is through the examination of tombs in the ancient Egyptian city of Thebes,
Which housed a necropolis containing many murals displaying the process of papyrus making.
The Roman commander Pliny the Elder also describes the methods of preparing papyrus in his Naturalis Historia.
In a dry climate like that of Egypt,
Papyrus is stable,
Formed as it is of highly rot-resistant cellulose,
But storage in humid conditions can result in molds attacking and destroying the material.
Library papyrus rolls were stored in wooden boxes and chests made in the form of statues.
Papyrus scrolls were organized according to subject or author,
And identified with clay labels that specified their contents without having to unroll the scroll.
In European conditions,
Papyrus seems to have lasted only a matter of decades.
A 200-year-old papyrus was considered extraordinary.
Imported papyrus,
Once commonplace in Greece and Italy,
Has since deteriorated beyond repair,
But papyri are still being found in Egypt.
Extraordinary examples include the Elephantine papyri and the famous finds at Aux Rincas and Nag Hammadi.
The Villa of the Papyri at Herculaneum,
Containing the library of Lucius Calpurnius Pisos Cisoninus,
Julius Caesar's father-in-law,
Was preserved by the eruption of Mount Vesuvius,
But has only been partially excavated.
Sporadic attempts to revive the manufacture of papyrus have been made since the mid-18th century.
Scottish explorer James Bruce experimented in the late 18th century with papyrus plants from Sudan.
Her papyrus had become extinct in Egypt.
Also in the 18th century,
Sicilian Saverio Landolina manufactured papyrus at Syracuse,
Where papyrus plants had continued to grow in the wild.
During the 1920s,
When Egyptologist Peres Khombegan lived in Maadi,
Outside Cairo,
He experimented with the manufacture of papyrus,
Growing the plant in his garden.
He beat the sliced papyrus stalks between two layers of linen and produced successful examples of papyrus,
One of which was exhibited in the Egyptian Museum in Cairo.
The modern technique of papyrus production used in Egypt for the tourist trade was developed in 1962 by the Egyptian engineer Hassan Ragab using plants that had been reintroduced into Egypt in 1872 from France.
Both Sicily and Egypt have centers of limited papyrus production.
Papyrus is still used by communities living in the vicinity of swamps,
To the extent that rural householders derive up to 75% of their income from swamp goods.
Particularly in East and Central Africa,
People harvest papyrus,
Which is used to manufacture items that are sold or used locally.
Examples include baskets,
Hats,
Fish traps,
Trays or winnowing mats,
And floor mats.
Papyrus is also used to make roofs,
Ceilings,
Rope,
And fences.
Although alternatives such as eucalyptus are increasingly available,
Papyrus is still used as fuel.
