Most concerning, though, is when the carbon dating directly opposes or contradicts other estimates. At this point, the carbon dating data is simply disregarded. It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew:. If it does not entirely contradict them, we put it in a footnote. And if it is completely out of date, we just drop it.

For example, recently science teams at the British Antarctic Survey and Reading University unearthed the discovery that samples of moss could be brought back to life after being frozen in ice. The kicker?

congratulate, the

That carbon dating deemed the moss to have been frozen for over 1, years. Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands.

Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate. Do you like or dislike what you have read?

The usual storehouse for such collections was in times gone by some unused garret or stable-loft, where rats and mice ran riot and birds flew in and out as they liked. The sad evidence of such poor storage conditions is seen all too often in searches among hoards of old deeds. Forgotten, perhaps, for several generations, the old documents lay untouched till death or removal brought changes, and the deeds were either placed in safer keeping, or else- and this was the most usual course -were consigned to the flames as useless rubbish.

It has always been my policy to stock and offer my customers only those old documents in the best available collectible, i. The size and shape of a deed at first glance goes far with the experienced reader to determine its age, even before a single word of it has been read; likewise the general ct will give a slight hint as to the possible contents without deciphering any of it.

The deeds relative to the earliest grants of land are very small in size, a marked contrast to the voluminous sheets of parchment considered necessary to a modern conveyance or deed. The writing often was minuscule, but each letter was carefully formed. The quality of parchment vellum varies much. That upon which early deeds - generally, before - are written, is in small pieces, woolly in texture and of a dark brown shade.

By the sixteenth century the sheets are larger, smoother and yellow, becoming whiter in color and more even as its preparation was better understood and practiced. Vellum was a fine sort of parchment prepared from the skins of very young or still-born animals.

absolutely not

Of it the oldest manuscript books were made, adorned with illuminations and miniature paintings, which required a fine, smooth surface, and vellum was free from the flaws which frequently occur in the skins of mature animals, which were routinely used in the largest size indentures.

Another important part of an ancient deed is the ink with which it was written. Each scribe had his own particular receipt for making it, the principal ingredients being oak-galls and sulfate of iron.

Many chemicals are recommended as restoratives for faded ink, but these should be avoided as far as possible, as they are liable to stain and disfigure the parchment, and in the end make matters worse. Familiarity with particular handwritings after some practice will enable the reader to make out otherwise unintelligible words without any other assistant than a powerful magnifying glass. If the ink is very faint the simplest and most harmless restorative is sulfate of ammonia; but its loathsome smell once endured is not easily forgotten; the experiment in consequence is very seldom repeated, for the result is scarcely good enough to risk a repetition of so horrible a smell, and it is liable to affect the MSS.

Dating Key Greek Bible Manuscripts. The Alexandrine Manuscript (Codex Alexandrinus), now held in the British Library, was the first of the major Bible manuscripts made available to scholars. It contains most of the Bible and is written in Greek uncials on vellum, a fine grade of parchment. This codex has been dated to the early fifth century C. "Indentures" are legal contracts, and are entirely written by hand (in English) on large sheepskins, in keeping with legal practice dating back to Medieval times. Today, these ancient British legal manuscripts are prized collector's items, and make impressive decorator accents when matted and framed. The top edge of the document shows the wavy, or "indented" margin that gives . Feb 10,   Having a basic knowledge of paper is important for collectors and dealers. Many fakes and reprints are identified as the paper is too modern or the wrong type for the print to be an original. This following a brief look at some important types of paper throughout history.

Colored inks or pigments were seldom, if ever, employed for legal documents. The use of these was restricted to the cloister, requiring manipulation by an illuminator instead of a mere scribe.

Red, blue, and green were in use; these were mineral colors. The red was composed either of red-lead or oxide of iron, the green from copper, and the blue from lapis lazuli finely powdered, or else it, too, like the green, was prepared from an oxide of copper.

Illuminating was a separate profession apart from that of writing. The charter or missal was finished by the scribe, and then handed over to the artist to be adorned with fanciful capital letters and elaborate scroll-works.

Such ornamentation was unnecessary for legal documents, yet sometimes these had fancy headings, which, like the illuminations, were put in after the writing was finished, as is proved by the occasional omission of them, although space is left where they ought to have been filled in.

Seals and seating-wax came into use gradually.

right! seems

The earliest deeds are very small, and have very small insignificant seals. It is said that neither the Saxon nor Norman noblemen could sign their own names, but instead employed the Christian sign of the cross still in use among the illiterate as their pledge of good faith, and to witness their consent and approval. The use of seals as appendices to deeds was a further proof that the deed itself was approved and executed. It was destroyed after death to avoid its being used for fraudulent purposes.

The use of signet-rings is very ancient. Many old Roman and Saxon signet-rings have been dug up from time to time in various parts of England. Small private seals bearing devices appear to have been attached to deeds of the fourteenth and fifteenth centuries. Many of the large wax seals are very beautiful, but few in private collections of deeds exist in any state of perfection. The wax used for them was either its natural color or else a sealing wax of a very dark green, also black, or red.

White, also, was used, now discolored by age into a dingy yellow. Besides the royal seals, each abbey had its own particular seal, bearing either a view of the abbey, a portrait of its patron saint, or its badge or shield. The fashion for large seals died out, till at last only royal grants or similar documents of the sixteenth century have them attached.

In the Georgian period and later we find small private seals placed on the margins of deeds. These were not always the arms and crest of the person against whose signature they appear - perhaps belonged to the lawyer or one of the contracting parties. Here it is that a knowledge of heraldry is extremely useful. Indentures are collected in a variety of ways, chiefly as the collector finds most rewarding.

A very popular use for the old documents is framed display. Such fascinating documents are, alas, virtually non-existent today, as it was the practice to burn them on discharge of their terms.

Collections are also formed containing a specimen from the reigns of the Kings and Queens whose names appear on them. Generally speaking indentures become obtainable on the collector market today starting with the reign of James I - Examples from earlier reigns are encountered quite infrequently. The earliest I have thus far located dates to the reign of Edward II - Documents dated during our War of Independence - are especially collectible today.

American manuscript material of the period is extremely uncommon and generally quite high priced, making these items from the mother country a fine, affordable alternative. With the name of the much-maligned last king of America George III on them, they are perfect association items from those turbulent times. Whether uterine vellum vellum made from aborted calf fetuses was ever really used during the medieval period is still a matter of great controversy.

There was a short period during the introduction of printing where parchment and paper were used interchangeably: although most copies of the Gutenberg Bible are on paper, some were printed on animal skins. InJohannes Trithemius preferred the older methods, because " handwriting placed on skin will be able to endure a thousand years. But how long will printing last, which is dependent on paper?

For if New techniques in paper milling allowed it to be much cheaper and more abundant than parchment. With the advent of printing in the later fifteenth century, the demands of printers far exceeded the supply of vellum and parchment.

The heyday of parchment use was during the medieval period, but there has been a growing revival of its use among contemporary artists since the late 20th century. Although it never stopped being used primarily for governmental documents and diplomas it had ceased to be a primary choice for artist's supports by the end of 15th century Renaissance. This was partly due to its expense and partly due to its unusual working properties.

It is also extremely affected by its environment and changes in humidity, which can cause buckling.

The History Of Vellum And Parchment

Some contemporary artists also prize this quality, noting that the skin seems alive and like an active participant in making the artwork. To support the needs of the revival of use by artists, a revival in the art of making individual skins is also underway.

Handmade skins are usually better prepared for artists and have fewer oily spots which can cause long-term cracking of paint than mass-produced parchment.

Mass-produced parchment is usually made for lamp shades, furniture, or other interior design purposes. The radiocarbon dating techniques that are used on papyrus can be applied to animal skins as well. They do not date the age of the writing but the preparation of the skin itself.

However, radiocarbon dating can often be used on the inks that make up the writing, since many of them contain organic compounds such as plant leachings, soot, and wine. Psalter: Psalm 83 "Quam dilecta tabernacula.

After being flayed, the skin is soaked in water for about 1 day. This removes blood and grime from the skin and prepares it 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 an unhairing bath included lime.

Today, the lime solution is occasionally sharpened by 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 contact with the alkaline solution.
