51-535: The manuscript is written on parchment . It contains 128 folios . Pages average approximately 293 × 215 mm with a writing surface of 250 × 185 mm (1 column, 30–33 lines in the main text). The manuscript has been copied in a single hand and shows signs of haste. The Moore Bede contains (with The Leningrad Bede ) one of the two earliest representatives of the m-type text of the Latin Historia ecclesiastica gentis Anglorum . The manuscript contains

102-556: A code of ethics and guidelines that establish the principles that guide conservation professionals and others who are involved in the care of cultural property. An example of a code of ethics and guidelines for practice were created by the American Institute for Conservation of Historic and Artistic Works (AIC) . One of the most important principles in a conservator's code of ethics is that treatments should be reversible, which means that one must be able to undo any treatment in

153-464: A copy of the Northumbrian aelda recension of Cædmon's Hymn on the last page of the manuscript, f. 128v. The poem is in the hand of a contemporary scribe , probably to be identified with that responsible for the so-called Memoranda on the same page (written in a larger script, but showing many similarities to the more cramped Cædmon’s Hymn and the main text of ff. 1r-128r). The Moore Bede

204-713: A cross-linked material with high density, stability and heat resistance and low surface tension which imparts good anti-stick or release properties. Chromium salts can also be used to impart moderate anti-stick properties. Historians believe that parchment craft originated as an art form in Europe during the fifteenth or sixteenth centuries. Parchment craft at that time occurred principally in Catholic communities, where crafts persons created lace-like items such as devotional pictures and communion cards. The craft developed over time, with new techniques and refinements being added. Until

255-413: A day to ensure the solution's deep and uniform penetration. Replacing the lime water bath also sped the process up. However, if the skins were soaked in the liquor too long, they would be weakened and not able to stand the stretching required for parchment. After soaking in water to make the skins workable, the skins were placed on a stretching frame. A simple frame with nails would work well in stretching

306-486: A graduate program in the United States, they will need to fulfill some undergraduate prerequisites. This includes undergraduate coursework in science, the humanities (art history, anthropology, and archaeology), and studio art. Some graduate programs may also require internship, volunteer, apprenticeship, or paid conservation experience. Many may also require a personal interview where candidates are asked to present

357-452: A natural non-porous cement, that gives to the vegetable parchment paper its resistance to grease and its semi-translucency. Other processes can be used to obtain grease-resistant paper, such as waxing the paper or using fluorine -based chemicals. Highly beating the fibers gives an even more translucent paper with the same grease resistance. Silicone and other coatings may also be applied to the parchment. A silicone -coating treatment produces

408-470: A particular material or group of objects, such as archaeology, ceramics and glass, furniture and wood, gilding and decorative surfaces, historic interiors, metals, paintings, paper and books, photographic materials, stained glass, stone and wall paintings, textiles, sculptures, architecture, time-based art and new media. The primary goal for conservators and restorers is the preservation of cultural property. In order to achieve this goal, conservators abide by

459-462: A portfolio of art and conservation project work that demonstrates manual dexterity and familiarity with techniques and materials. Graduate programs generally require two to four years of study, which can also include a full-time internship in the final year where students work under the guidance of experienced conservators. There are also a limited number of Ph.D. programs for advanced study in conservation. Conservation-related programs are described on

510-646: A primary choice for artists' supports by the end of the 15th century Renaissance . This was partly due to its expense and partly due to its unusual working properties. Parchment consists mostly of collagen . When the water in paint media touches the parchment's surface, the collagen melts slightly, forming a raised bed for the paint, a quality highly prized by some artists. Parchment is also extremely affected by its environment and changes in humidity, which can cause buckling. Books with parchment pages were bound with strong wooden boards and clamped tightly shut by metal (often brass) clasps or leather straps; this acted to keep

561-406: A raised effect, stippling, perforating, coloring and cutting. Parchment craft appears in hand made cards, as scrapbook embellishments, as bookmarks, lampshades, decorative small boxes, wall hangings and more. The radiocarbon dating techniques that are used on papyrus can be applied to parchment as well. They do not date the age of the writing but the preparation of the parchment itself. While it

612-431: A small DNA sample to a size sufficiently large for testing. The article discusses the use of DNA testing to estimate the age of the calf at the creation of the vellum parchment. A 2006 study revealed the genetic signature of several Greek manuscripts to have "goat-related sequences". Utilizing these techniques we may be able to determine whether related library materials were made from genetically related animals (perhaps from

663-399: A waterleaf (an unsized paper like blotters) made of pulp fibers into sulfuric acid . The sulfuric acid hydrolyses and solubilises the main natural organic polymer, cellulose, present in the pulp wood fibers. The paper web is then washed in water, which stops the hydrolysis of the cellulose and causes a kind of cellulose coating to form on the waterleaf. The final paper is dried. This coating is

714-481: A wooden frame known as a stretching frame. After a carcass is skinned , the hide is soaked in water for about a day. This removes blood and grime and prepares the skin for a dehairing liquor. The dehairing liquor was originally made of rotted, or fermented, vegetable matter, like beer or other liquors, but by the Middle Ages a dehairing bath included lime . Today, the lime solution is occasionally sharpened by

765-537: A writing medium for over two millennia. Vellum is a finer quality parchment made from the skins of young animals such as lambs and young calves. The generic term animal membrane is sometimes used by libraries and museums that wish to avoid distinguishing between parchment and vellum. The word is derived from the Koinē Greek city name, Pergamum in Anatolia , where parchment was supposedly first developed around

816-400: Is a professional responsible for the preservation of artistic and cultural artifacts , also known as cultural heritage . Conservators possess the expertise to preserve cultural heritage in a way that retains the integrity of the object, building or site, including its historical significance, context and aesthetic or visual aspects. This kind of preservation is done by analyzing and assessing

867-421: Is a subset of the umbrella term "conservation". Both terms come into play when it comes to the treatment and care of all cultural heritage. Conservators and restorers care for, manage, treat, preserve, and document many different historical items including artifacts , art , and specimens. Conservators can receive training through apprenticeships, internships and graduate programs. In order to be accepted into

918-453: Is also underway. Hand-prepared skins are usually preferred by artists because they are more uniform in surface and have fewer oily spots – which can cause long-term cracking of paint – than mass-produced parchment, which is usually made for lamp shades, furniture, or other interior design purposes. Parchment is prepared from pelt – i.e. wet, unhaired, and limed skin – by drying at ordinary temperatures under tension, most commonly on

969-505: Is feasibly possible also to radiocarbon date certain kinds of ink, it is extremely difficult to do due to the fact that they are generally present on the text only in trace amounts, and it is hard to get a carbon sample of them without the carbon in the parchment contaminating it. An article published in 2009 considered the possibilities of tracing the origin of medieval parchment manuscripts and codices through DNA analysis. The methodology would employ polymerase chain reaction to replicate

1020-579: Is for these reasons that many modern conservators , librarians and archivists prefer to use either the broader term parchment , or the neutral term animal membrane . The word parchment evolved (via the Latin pergamenum and the French parchemin ) from the name of the city of Pergamon , which was a thriving center of parchment production during the Hellenistic period . The city so dominated

1071-476: Is now thought "likely to be English in origin" (Ker 1990). Bischoff has shown that the manuscript was at the Palace School at Aachen around CE 800. Parkes suggests that it may have been sent to there from York at the request of Alcuin . Parchment Parchment is a writing material made from specially prepared untanned skins of animals—primarily sheep, calves, and goats. It has been used as

1122-453: Is produced by large companies in Israel . This usage is Sinaitic in origin, with special designations for different types of parchment such as gevil and klaf . For those uses, only hides of kosher animals are permitted. Since there are many requirements for it being fit for the religious use, the liming is usually processed under supervision of a qualified Rabbi . In some universities,

1173-473: Is traditionally dated to 734–737 on the basis of the so-called Moore Memoranda, a series of chronological notes preserved on f. 128v. Although the validity of these (and similar notes in The Leningrad Bede) as evidence for the manuscript’s date has been challenged vigorously, the manuscript can be dated securely to the 8th century on palaeographic and codicological grounds. The manuscript

1224-547: The Assyrians and the Babylonians most commonly impressed their cuneiform on clay tablets, but they also wrote on parchment from the 6th century BC onward. By the fourth century AD, in cultures that traditionally used papyrus for writing, parchment began to become the new standard for use in manufacturing important books, and most works which wished to be preserved were eventually moved from papyrus to parchment. In

1275-817: The Fourth Dynasty (c. 2550–2450 BC), but the earliest of such documents extant are: a fragmentary roll of leather of the Sixth Dynasty (c. 24th century BC), unrolled by Dr. H. Ibscher, and preserved in the Cairo Museum ; a roll of the Twelfth Dynasty (c. 1990–1777 BC) now in Berlin; the mathematical text now in the British Museum (MS. 10250); and a document of the reign of Ramses II (early thirteenth century BC)." Civilizations such as

1326-831: The Getty Foundation , the Smithsonian's Museum Conservation Institute , and the Straus Center of Harvard Art Museums . The specialty of conservation is ever-changing and evolving, which means that practicing conservators must stay up-to-date of advances in technology and methodology. Conservators usually expand their knowledge through reading publications, attending professional meetings, and enrolling in short-term workshops or courses. AIC offers many workshops, conferences, and online courses and tutorials. Conservation OnLine (CoOL) also offers resources for conservation professionals. Some conservators specialize in

1377-540: The Vienna Genesis , which at least at one time are believed to have been reserved for Imperial commissions. Many techniques for parchment repair exist, to restore creased, torn, or incomplete parchments. Between the seventh and the ninth centuries, many earlier parchment manuscripts were scrubbed and scoured to be ready for rewriting, and often the earlier writing can still be read. These recycled parchments are known as palimpsests . The way in which parchment

1428-414: The public . Essentially, the term "conservation" refers to a manner of care or treatment that repairs damage and also takes action to prevent or slow down further deterioration of an object. The term "restoration" refers to a manner of care or treatment in which the goal is to bring an object back to its original appearance or function. "Restoration" can be part of the care and treatment of an object and

1479-539: The 5th century BC; and in his Histories (v.58) he states that the Ionians of Asia Minor had been accustomed to give the name of skins ( diphtherai ) to books; this word was adapted by Hellenized Jews to describe scrolls. Writing on prepared animal skins had a long history in other cultures outside of the Greeks as well. David Diringer noted that "the first mention of Egyptian documents written on leather goes back to

1530-410: The condition of cultural property, understanding processes and evidence of deterioration, planning collections care or site management strategies that prevent damage, carrying out conservation treatments, and conducting research. A conservator's job is to ensure that the objects in a museum's collection are kept in the best possible condition, as well as to serve the museum's mission to bring art before

1581-505: The demands of printers. There was a short period during the introduction of printing where parchment and paper were used at the same time, with parchment (in fact vellum) the more expensive luxury option, preferred by rich and conservative customers. Although most copies of the Gutenberg Bible are on paper, some were printed on parchment; 12 of the 48 surviving copies, with most incomplete. In 1490, Johannes Trithemius preferred

1632-438: The eighteenth century, people were regaining interest in detailed handwork. Parchment cards became larger in size and crafters began adding wavy borders and perforations. In the nineteenth century, influenced by French romanticism, parchment crafters began adding floral themes and cherubs and hand embossing. Parchment craft today involves various techniques, including tracing a pattern with white or colored ink, embossing to create

1683-440: The following exchange occurs: Hamlet. Is not parchment made of sheepskins? Horatio. Ay, my lord, and of calves' skins too. Lee Ustick, writing in 1936, commented: To-day the distinction, among collectors of manuscripts, is that vellum is a highly refined form of skin, parchment a cruder form, usually thick, harsh, less highly polished than vellum, but with no distinction between skin of calf, or sheep, or of goat. It

1734-426: The frame they would keep their form. The stretching aligned the fibres to be more nearly parallel to the surface. To make the parchment more aesthetically pleasing or more suitable for the scribes , special treatments were used. According to Reed there were a variety of these treatments. Rubbing pumice powder into the flesh side of parchment while it was still wet on the frame was used to make it smooth and to modify

1785-519: The institution of employing parchment made of animal hides for the writing of ritual objects, as detailed below. In the United Kingdom, Acts of Parliament are still printed on vellum. The heyday of parchment use was during the medieval period, but there has been a growing revival of its use among artists since the late 20th century. Although parchment never stopped being used (primarily for governmental documents and diplomas) it had ceased to be

1836-439: The later Middle Ages , especially the 15th century, parchment was largely replaced by paper for most uses except luxury manuscripts, some of which were also on paper. New techniques in paper milling allowed it to be much cheaper than parchment; it was made of textile rags and of very high quality. Following the arrival of printing in the later fifteenth century AD, the supply of animal skins for parchment could not keep up with

1887-482: The older methods, because "handwriting placed on parchment will be able to endure a thousand years. But how long will printing last, which is dependent on paper? For if ... it lasts for two hundred years that is a long time." In fact, high-quality paper from this period has survived 500 years or more very well, if kept in reasonable library conditions. Parchment (or vellum) continues to be use for ritual or legal reasons. Rabbinic literature traditionally maintains that

1938-433: The pages pressed flat despite humidity changes. Such metal fittings continued to be found on books as decorative features even after the use of paper made them unnecessary. Some contemporary artists prize the changeability of parchment, noting that the material seems alive and like an active participant in making artwork. To support the needs of the revival of use by artists, a revival in the art of preparing individual skins

1989-399: The pelts. The skins could be attached by wrapping small, smooth rocks in the skins with rope or leather strips. Both sides would be left open to the air so they could be scraped with a sharp, semi-lunar knife to remove the last of the hair and get the skin to the right thickness. The skins, which were made almost entirely of collagen , would form a natural glue while drying and once taken off

2040-471: The precise animal origin of a skin, either in terms of its species or in terms of the animal's age. In practice, therefore, there has long been considerable blurring of the boundaries between the different terms. In 1519, William Horman wrote in his Vulgaria : "That stouffe that we wrytte upon, and is made of beestis skynnes, is somtyme called parchement, somtyme velem, somtyme abortyve, somtyme membraan." In Shakespeare 's Hamlet (written c. 1599–1602)

In 2020, it was reported that the species of several of the animals used to provide parchment for the Dead Sea Scrolls could be identified, and the relationship between skins obtained from the same animal inferred. The breakthrough was made possible by the use of whole genome sequencing . Conservator-restorer A conservator-restorer

2142-400: The second century BCE, probably as a substitute for papyrus . Today the term parchment is often used in non-technical contexts to refer to any animal skin, particularly goat , sheep or cow , that has been scraped or dried under tension. The term originally referred only to the skin of sheep and, occasionally, goats. The equivalent material made from calfskin, which was of finer quality,

2193-438: The sixteenth century, parchment craft was a European art form. However, missionaries and other settlers relocated to South America, taking parchment craft with them. As before, the craft appeared largely among the Catholic communities. Often, young girls receiving their first communion received gifts of handmade parchment crafts. Although the invention of the printing press led to a reduced interest in hand made cards and items, by

2244-406: The surface to enable inks to penetrate more deeply. Powders and pastes of calcium compounds were also used to help remove grease so the ink would not run. To make the parchment smooth and white, thin pastes (starchgrain or staunchgrain) of lime, flour, egg whites and milk were rubbed into the skins. Meliora di Curci in her paper, "The History and Technology of Parchment Making", notes that parchment

2295-587: The trade that a legend later arose which said that parchment had been invented in Pergamon to replace the use of papyrus which had become monopolized by the rival city of Alexandria . This account, originating in the writings of Pliny the Elder ( Natural History , Book XIII, 69–70), is almost assuredly false because parchment had been in use in Anatolia and elsewhere long before the rise of Pergamon. Herodotus mentions writing on skins as common in his time,

2346-412: The use of sodium sulfide. The liquor bath would have been in wooden or stone vats and the hides stirred with a long wooden pole to avoid human contact with the alkaline solution. Sometimes the skins would stay in the dehairing bath for eight or more days depending how concentrated and how warm the solution was kept – dehairing could take up to twice as long in winter. The vat was stirred two or three times

2397-588: The websites of the AIC, the National Council for Preservation Education (NCPE), and the Society of American Archivists (SAA) . Post-graduate fellowships have also been cited as valuable experiences in their professional development. These fellowships provide intensive research, practice, and exposure to diverse professional staff or significant collections. A few institutions that offer fellowships include

2448-408: The word parchment is still used to refer to the certificate (scroll) presented at graduation ceremonies, even though the modern document is printed on paper or thin card; although doctoral graduates may be given the option of having their scroll written by a calligrapher on vellum. Heriot-Watt University still uses goatskin parchment for their degrees. Vegetable (paper) parchment is made by passing

2499-638: Was known as vellum (from the Old French velin or vellin , and ultimately from the Latin vitulus , meaning a calf); while the finest of all was uterine vellum , taken from a calf foetus or stillborn calf. Some authorities have sought to observe these distinctions strictly: for example, lexicographer Samuel Johnson in 1755, and master calligrapher Edward Johnston in 1906. However, when old books and documents are encountered it may be difficult, without scientific analysis, to determine

2550-642: Was not always white. " Cennini , a 15th-century craftsman provides recipes to tint parchment a variety of colours including purple, indigo, green, red and peach." The Early medieval Codex Argenteus and Codex Vercellensis , the Stockholm Codex Aureus and the Codex Brixianus give a range of luxuriously produced manuscripts all on purple vellum , in imitation of Byzantine examples, like the Rossano Gospels , Sinope Gospels and

2601-533: Was processed (from hide to parchment) has undergone a tremendous evolution based on time and location. Parchment and vellum are not the sole methods of preparing animal skins for writing. In the Babylonian Talmud ( Bava Batra 14B), Moses is described as having written the first Torah Scroll on the unsplit cow-hide called gevil . Parchment is still the only medium used by traditional religious Jews for Torah scrolls or tefilin and mezuzahs , and
