79-465: A scroll (from the Old French escroe or escroue ), also known as a roll , is a roll of papyrus , parchment , or paper containing writing. A scroll is usually partitioned into pages, which are sometimes separate sheets of papyrus or parchment glued together at the edges. Scrolls may be marked divisions of a continuous roll of writing material . The scroll is usually unrolled so that one page
158-500: A 2D image, the writing on this inside can be revealed. This process happens in three steps: segmentation, texturing and flattening. The first stage of the virtual unwrapping process, segmentation, involves identifying geometric models for the structures within the virtual scan of the scroll. Because of the extensive damage, the parchment has become deformed and no longer has a clearly cylindrical geometry. Instead, some portions may look planar, some conical, some triangular, etc. Therefore,
237-413: A 3D mapping which differentiates between the ink and the paper. The virtual unwrapping process is independent of which type of volumetric scan is used, which allows scientists to test out different scanning methods to find which distinguishes ink from paper best and which easily accommodates scanning upgrades. The only data needed for the virtual unwrapping process is this volumetric scan, so after this point
316-467: A codex is the term used primarily for a bound manuscript from Roman times up through the Middle Ages. From the fourth century on, the codex became the standard format for books, and scrolls were no longer generally used. After the contents of a parchment scroll were copied in codex format, the scroll was seldom preserved. The majority that did survive were found by archaeologists in burial pits and in
395-409: 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
474-624: A loanword of unknown (perhaps Pre-Greek ) origin. Greek has a second word for it, βύβλος ( byblos ), said to derive from the name of the Phoenician city of Byblos . The Greek writer Theophrastus , who flourished during the 4th century BCE, uses papyros when referring to the plant used as a foodstuff and byblos for the same plant when used for nonfood products, such as cordage, basketry, or writing surfaces. The more specific term βίβλος biblos , which finds its way into English in such words as 'bibliography', 'bibliophile', and 'bible', refers to
553-453: A long roll, or scroll, was required to create large-volume texts. 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 Europe by
632-473: A lower section of the Villa's collection that remains buried. Ethel Ross Barker noted in her 1908 Buried Herculaneum : Appearance of the rolls. — A large number of papyri, after being buried eighteen centuries, have been found in the Villa named after them. In appearance the rolls resembled lumps of charcoal; and many were thrown away as such. Some were much lighter in colour. Finally, a faint trace of letters
711-681: 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 Oxyrhynchus and Nag Hammadi . The Villa of the Papyri at Herculaneum , containing the library of Lucius Calpurnius Piso Caesoninus , Julius Caesar 's father-in-law,
790-417: A mixture of ethanol, glycerin, and warm water, in hopes to make scrolls readable. According to Antonio de Simone and Richard Janko, at first the papyri were mistaken for carbonized tree branches, some perhaps even thrown away or burnt to make heat. What we see is that the ink, which was essentially carbon based, is not very different from the carbonised papyrus. Opening a scroll would often damage or destroy
869-479: A papyrus was taken to a laboratory in the Louvre. An attempt to unravel it was made with a "small mill", but it was unsuccessful and was partially destroyed, leaving only a quarter intact. By the middle of the 20th century, only 585 rolls or fragments had been completely unrolled, and 209 unrolled in part. Of the unrolled papyri, about 200 had been deciphered and published, and about 150 only deciphered. The bulk of

From 1819 until 1820, Humphry Davy was commissioned by the prince regent George IV to work on the Herculaneum papyri. Although it is considered that he had only limited success, Davy's chemical method, which used chlorine, managed to partially unroll 23 manuscripts. In 1877,
1027-436: A rival writing surface that rose in prominence known as parchment , which was made from animal skins . By the beginning of the fourth century A.D., 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
1106-527: A room to the north. In the spring and summer of the following year, 337 Greek papyri and 18 Latin papyri were found in the Library. Nothing of any importance was discovered after this date. The numbers given here exclude mere fragments. Including every tiny fragment found, the catalogues give 1756 manuscripts discovered up to 1855, while subsequent discoveries bring the total up to 1806. Of these, 341 were found almost entire, 500 were merely charred fragments, and
1185-469: A spot with a blank space. This means that when the radiation emerges from the paper, its phase will be slightly different than that of the empty space, allowing researchers to distinguish ink-covered spots from blank spots. While this technique does allow researchers to visualize places with ink, it is much less clear than techniques such as CT scans which distinguish between different materials because slight changes (thinner ink, thicker papyrus, folds in
1264-529: A team working with Institut de Papyrologie and a group of scientists from Kentucky have been using X-rays and nuclear magnetic resonance to analyze the artifacts. In 2009, the Institut de France in conjunction with the French National Centre for Scientific Research imaged two intact Herculaneum papyri using X-ray micro-computed tomography (micro-CT) to reveal the interior structures of
1343-501: Is a material similar to thick paper that was used in ancient times as a writing surface . It was made from the pith 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

In ideal cases, the scanned volume will match perfectly with the surface of each geometric piece and yield perfectly rendered text, but there are often small errors in the segmentation process that generate noise in the texturing process. Because of this, the texturing process usually includes nearest-neighbor interpolation texture filtering to reduce
1501-559: Is exposed at a time, for writing or reading, with the remaining pages rolled and stowed to the left and right of the visible page. Text is written in lines from the top to the bottom of the page. Depending on the language, the letters may be written left to right, right to left, or alternating in direction ( boustrophedon ). Scrolls were the first form of editable record keeping texts, used in Eastern Mediterranean ancient Egyptian civilizations . Parchment scrolls were used by
1580-401: Is hope that the continuing work on the library scrolls will discover some of these. For example, as many as 44 works discovered were written by the 1st-century BC Epicurean philosopher and poet Philodemus , a resident of Herculaneum, who possibly formed the library, or whose library was incorporated in it. Due to the eruption of Mount Vesuvius in 79 AD, bundles of scrolls were carbonized by
1659-479: Is impossible to believe that the Christian adoption of the codex can have taken place any later than circa A.D. 100 (it may, of course, have been earlier)". There were certainly practical reasons for the change. Scrolls were awkward to read if a reader wished to consult material at opposite ends of the document. Further, scrolls were written only on one side, while both sides of the codex page were used. Eventually,

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
1817-453: Is that the lines of writing in rotuli run across the width of the roll (that is to say, are parallel with any unrolled portion) rather than along the length, divided into page-like sections. Rolls may be wider than most scrolls, up to perhaps 60 cm or two feet wide. Rolls were often stored together in a special cupboard on shelves. A special Chinese form of short book, called the "whirlwind book", consists of several pieces of paper bound at
1896-421: 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. Herculaneum papyri The Herculaneum papyri are more than 1,800 papyrus scrolls discovered in

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 ranged from

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 third millennium BCE. The earliest archaeological evidence of papyrus
2133-587: The Islamic world , which originally learned of it from the Chinese. 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
2212-613: The Israelites among others before the codex or bound book with parchment pages was invented by the Romans, which became popular around the 1st century AD. Scrolls were more highly regarded than codices until well into Roman times. The ink used in writing scrolls had to adhere to a surface that was rolled and unrolled, so special inks were developed. Even so, ink would slowly flake off scrolls. Shorter pieces of parchment or paper are called rolls or rotuli , although usage of

The latest certain dates for the use of papyrus in Europe are 1057 for a papal decree (typically conservative, all papal bulls were on papyrus until 1022), under Pope Victor II , and 1087 for an Arabic document. Its use in Egypt continued until it was replaced by less expensive paper introduced by
2370-406: The 1000-2500 nm range, detects ink on unrolled papyri better than the 950 nm technique does. Several research groups proposed to unroll the scrolls virtually, using X-ray phase-contrast tomography (XPCT, "phase-contrast CT"), possibly with a synchrotron light source . Proposed method has three steps: volumetric scanning, segmentation, layered texture generation and restoration. Since 2007,

The papyri, containing a number of Greek philosophical texts , come from the only surviving library from antiquity that exists in its entirety. However, reading the scrolls is extremely difficult, and can risk destroying them. The evolution of techniques to do this continues. The majority of classical texts referred to by other classical authors are lost, and there

2528-507: 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 (16 in) long. The strips were then placed side by side on

In a 2016 open letter, academics asked the Italian authorities to consider new excavations, since it is assumed that many more papyri may be buried at the site. Authors argue that "the volcano may erupt again and put
2686-400: The ancient world is always going to be excited to get even one paragraph, one chapter, more... The prospect of getting hundreds of books more is staggering. In the 18th century, the first digs began. The excavation appeared closer to mining projects, as mineshafts were dug, and horizontal subterranean galleries were installed. Workers would place objects in baskets and send them back up. With

Father Piaggio, invented a very simple machine for unrolling the manuscripts by means of silk threads attached to the edge of the papyrus. Of course this method destroyed the beginning of all the papyri, sometimes the end could not be found, and the papyri were in a terrible state of decay. Anybody who focuses on

Carlo Bonucci. In the year 1868 still further purchases of land were made, and excavations were carried on in an eastward direction till 1875. The total area now open measures 300 by 150 perches (1510 by 756 meters). The limits of

The surface on which the ink was applied was kept flat, not subjected to weakening by the repeated bending and unbending that scrolls undergo as they are alternately rolled up for storage and unrolled for reading, which creates physical stresses in both the papyrus and the ink of scrolls. The term codex technically refers only to manuscript books — those that, at one time, were handwritten. More specifically,

In September 2016, Brent Seales, a computer scientist at the University of Kentucky , successfully used virtual unrolling to read the text of a charred parchment from Israel, the En-Gedi Scroll . The virtual unwrapping process begins with using a volumetric scan to scan the damaged scroll. These scans are non-invasive, and generate

The first were found in the autumn of 1752, fourteen years after the first discovery of Herculaneum, in and near the tablinum, and only numbered some 21 volumes and fragments, contained in two wooden cases. In the spring of 1753, 11 papyri were found in a room just south of the tablinum, and in the summer of the same year, 250 were found in

Stemming from a passage in Suetonius' Divus Julius (56.6), legend has it that Julius Caesar was the first to fold scrolls, concertina-fashion, for dispatches to his forces campaigning in Gaul. But the precise meaning of the passage is by no means clear. As C. H. Roberts and T. C. Skeat point out, the idea that " Julius Caesar may have been
3476-463: The excavations to the north and east respectively are the modern streets of Vico di Mare and Vico Ferrara. It is here only that any portion of ancient Herculaneum may be seen in the open day." It is uncertain how many papyri were originally found as many of the scrolls were destroyed by workmen or when scholars extracted them from the volcanic tuff . The official list amounts to 1,814 rolls and fragments, of which 1,756 had been discovered by 1855. In
3555-565: The folds were cut into sheets, or "leaves", and bound together along one edge. The bound pages were protected by stiff covers, usually of wood enclosed with leather. Codex is Latin for a "block of wood": the Latin liber , the root of "library", and the German Buch , the source of "book", both refer to wood. The codex was not only easier to handle than the scroll, but it also fit conveniently on library shelves. The spine generally held
3634-459: 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

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

This intense parching took place over an extremely short period of time, in a room deprived of oxygen, resulting in the scrolls' carbonization into compact and highly fragile blocks. They were then preserved by the layers of cement-like rock. In 1752, workmen of the Bourbon royal family accidentally discovered what is now known as the Villa of the Papyri . There may still be
3871-491: The inventor of the codex... is indeed a fascinating proposition; but in view of the uncertainties surrounding the passage, it is doubtful whether any such conclusion can be drawn". What the evidence of surviving early codices does make clear is that Christians were among the earliest to make widespread use of the codex. Several Christian papyrus codices known to us date from the second century, including at least one generally accepted as being no later than A.D. 150. "All in all, it

XPCT, on the other hand, examines the phase of X-ray radiation after it emerges from the scroll to determine its composition. Because the ink is raised relative to the papyrus, the radiation will be traveling in the material of the scroll slightly longer when it passes through a spot with ink than when it passes through

Normally, texts were first written on the recto , the lines following the fibres, parallel to the long edges of the scroll. Secondarily, papyrus was often reused, writing across the fibres on the verso . One source used for determining

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
4187-408: The most efficient way to assign a geometry to the layer is to do so in a piecewise fashion. Rather than modeling the complex geometry of the entire layer of the scroll, the piecewise model breaks each layer into more regular shapes that are easy to work with. This makes it easy to virtually lift off each piece of the layer one at a time. Because each voxel is ordered, peeling off each layer will preserve

This is, in practice, enough to 'read' the inside of the scroll, but it is often best to convert this to a 2D flat image to demonstrate what the scroll's parchment would have looked like if they could physically unravel without damage. This requires

Father Antonio Piaggio 's machine. — Through this inevitable ignorance of the time, a larger number of the rolls were destroyed than the difficulties of the case necessitated. Many had been thrown away as mere charcoal; some were destroyed in extracting them from the lava in which they were embedded. In

The volumetric scan is used to associate the composition of the scroll with corresponding positions, called voxels or volume-pixels. The goal of the virtual unwrapping process is to determine the layered structure of the scroll and try to peel back each layer while keeping track of which voxel. By transforming the voxels from a 3D volumetric scan to

In 1969, Marcello Gigante founded the creation of the International Center for the Study of the Herculaneum Papyri ( Centro Internazionale per lo Studio dei Papiri Ercolanesi ; CISPE). With the intention of working toward the resumption of the excavation of the Villa of the Papyri , and promoting

MSI helps spot ink because the ink and the charred papyrus have different reflectivities in the 950 nm infrared band. The images are not actually "multispectral", but consist only of data in this 950-nm band. In 2019, a multinational European team reported that SWIR HSI (shortwave-infrared hyperspectral imaging), which combines several bands in

This method of volumetric scanning was chosen because Herculaneum papyri have carbon-based ink, which will have the same material characteristics as the carbon-based papyrus. This makes it difficult to image using many of the traditional imaging techniques, which often use differences in

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 (the most expensive books, made from foetal vellum would take up to dozens of bovine fetuses to produce). However, as trade networks declined, the availability of papyrus outside the range of the papyrus plant became limited and it thus lost its cost advantage. Papyrus' last appearance in

These documents, the Diary of Merer , date from c. 2560 –2550 BCE (end of the reign of Khufu ). 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
5925-570: 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 Reuvens (1793–1835). He wrote about the content of the Leyden papyrus , published in 1830. The first publication has been credited to the British scholar Charles Wycliffe Goodwin (1817–1878), who published for
6004-472: 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 , for 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
6083-404: Was seen on one of the blackened masses, which was found to be a roll of papyrus, disintegrated by decay and damp, full of holes, cut, crushed, and crumpled. The papyri were found at a depth of about 120 feet (37 metres). The woodwork of some of the presses that had contained them dropped to dust on exposure and many rolls were found lying about loosely. Others were still on the shelves. Locality of
6162-472: Was then dried under pressure. After drying, the sheet was polished with a rounded object, possibly a stone, seashell , or round hardwood. Sheets, or Mollema, could be cut to fit the obligatory size or glued together to create a longer roll. The point where the Mollema are joined with glue is called the kollesis. A wooden stick would be attached to the last sheet in a roll, making it easier to handle. To form
6241-482: Was used for hundreds of scrolls, and in the process destroyed them. In 1756, Abbot Piaggio, conserver of ancient manuscripts in the Vatican Library , used a machine he also invented, to unroll the first scroll, which took four years (millimeters per day). The results were then copied (since the writing disappeared: see above), reviewed by Hellenist academics, and then corrected once more, if necessary, by
