Pre-Columbian mesoamerican codices (Mexico and Central America) had a similar appearance when closed to the European codex, but were instead made with long folded strips of fig bark (amatl) or plant fibers, often with a layer of lime applied before writing. The New World codices were not written until the 16th century (see Mayan and Aztec codices). Those written before the Spanish conquests all seem to have been long, simple sheets in the accordion style, sometimes written on both sides of Amatl paper. There are important codices produced in colonial times, with pictorial and alphabetical texts in Spanish or in an indigenous language such as Nahuatl. [25] In his discussion of one of the first surviving parchment codices of Oxyrhynchus in Egypt, Eric Turner seems to question Skeat`s notion when he asserts that «his very existence is proof that this form of book had prehistory» and that «the first experiments with this form of book may have taken place outside Egypt.» [19] The first parchment or papyrus codices seem to have been widely used as personal notebooks, for example in the recording of copies of letters (Cicero Fam. 9.26.1). The first codes were not always consistent. They often included several languages, different subjects, and even several authors. [20] The pages of the parchment notebook were «more durable and could be folded and sewn onto other sheets.» Scrolls whose writing was no longer necessary were usually washed or scraped for reuse, creating a palimpsest; Deleted text, which can often be recovered, is older and generally more interesting than the newer text that replaced it.

Therefore, writings in a codex were often considered informal and volatile. [21] [4] Parchment (animal skin) was expensive and was therefore mainly used by the rich and powerful, who could also pay for text design and color. «Official documents and luxury manuscripts [in the late Middle Ages] were written in gold and silver ink on parchment. dyed or painted with expensive purple pigments as an expression of imperial power and wealth. [4] Codex (plural codexes) Manuscript sewn together in the form of a book, with a spine and often a cover. The form of the codex replaced the scroll as the most common manuscript form in the early Christian period. Click here for the debate. The code offered significant advantages over other book formats, including its compactness, robustness, economical use of materials through the use of both sides (front and back), and easy reference (a code allows random access, as opposed to scrolling that uses sequential access). [13] Traditional binders would refer to one of these composite, cropped and bound folios (i.e., the «pages» of the book as a whole, consisting of the front and content) as a codex as opposed to the cover or case, thus creating the format of the book, now colloquially referred to as hardcover. In the hardcover binding process, the method of binding the code is very different from the process of manufacturing and fixing the case.

[Citation needed] The first step in creating a code is to prepare the animal`s skin. The skin is washed with water and lime, but not together. The skin is soaked in lime for a few days. [30] The hair is removed and the skin dried by attaching it to a frame called a harrow. [31] [Page needed] Parchment attaches the skin to points around the perimeter. The skin adheres to its own with cords. To prevent it from being torn, the manufacturer wraps the area of skin attached to the string around a pebble called a pippin. [31] [Page needed] Once this is complete, the manufacturer uses a crescent-shaped knife called lunarium or lunell to remove any remaining hair. Once the skin dries completely, the manufacturer gives it a deep cleanse and turns it into leaves. The number of leaves of a piece of skin depends on the size of the skin and the dimensions of the final product.

For example, medium calf leather can provide three and a half average sheets of writing material that can be lined when folded into two common sheets, also known as bifolium. Historians have found evidence of manuscripts in which the scribe wrote the medieval instructions followed by modern membrane makers. [32] Defects can often be found in the membrane, whether they come from the animal of origin, from human error during the preparation period, or from the time the animal was killed. Defects may also occur during the writing process. If the manuscript is not kept in perfect condition, defects can also occur later in life. [Citation needed] In East Asia, the roller remained standard much longer than in the Mediterranean world. There were intermediate steps, such as rolls folded into accordion and glued together on the back, and books printed only on one side of the paper. [26] This has replaced traditional Chinese writing techniques such as bamboo and wooden sheets, as well as silk and paper rolls. [27] The development of the codex in China began with folded pamphlets in the 9th century, at the end of the Tang Dynasty (618-907), reinforced by the «butterfly» bindings of the Song Dynasty (960-1279), the wrapped binding of the Yuan Dynasty (1271-1368), the sewn binding of the Ming (1368-1644) and Qing (1644-1912) dynasties, and finally the introduction of Western-style binding in the 20th century. [28] [Review Failure] The initial phase of this development, the palm leaf-style book folded with accordion, probably came from India and was introduced to China by Buddhist missionaries and scriptures.

[28] [Journal Failure] In Western culture, the codex gradually replaced the scroll. Between the 4th century, when the codex was widely accepted, and the Carolingian Renaissance in the 8th century, many works were lost that were not converted from the scroll to the codex. The codex has improved scrolling in several ways. It could be opened flat on either side for ease of reading, pages could be written on both the front and back (front and back), and the protection of durable covers made it more compact and easier to carry. [24] Already at the beginning 2. In the twentieth century, there is evidence that a codex – mainly in papyrus – was the preferred format of Christians.
