They've plotted rings from shipwreck timbers and roof beams, and wood from the Mediterranean, Russia, and China. Radioactive dating gives hope for an objective empirical method of determining the age of fossils. That is the true benefit of radiocarbon dating, that it can be employed anywhere in the world, and does have about a 60, year range. The bristlecone pine series, the longest built from a single species in a single location, stretches back to This, of course, would not affect the C dating of the shroud of Turin, which is drawbacks of carbon dating subject of hot debate between some scientists who believe that the shroud was created in medieval times and some conservative Christians who believe that the shroud was used in Jesus' drawbacks of carbon dating and thus is dated to the 1st century CE.

Radiocarbon dating, or simply carbon dating, is a technique that uses the decay of. The numbers 12, 13 and 14 refer to the total number of protons plus neutrons in the atom's nucleus. This will enable the reader to gain an appreciation of the advantages and disadvantages of this process.

This significantly impacts the accuracy of carbon-based dating. On April 26, this facility celebrated 25 years of operation, during which time it had processed over 75, radiocarbon measurements on objects ranging from the Dead Sea Scrolls to the Shroud of Turin. Radiocarbon dating was developed by Willard F.

Contamination is a huge threat to the accuracy of radiocarbon dating. Carbon has an atomic number of 6, an atomic weight of The numbers 12, 13 and 14 refer to the total number of protons plus neutrons in the atom's nucleus. Thus carbon has six protons and eight neutrons. Carbon is by far the most abundant carbon isotope, and carbon and are both stable.

But carbon is slightly radioactive: Why doesn't the carbon in the air decay along with terrestrial carbon? The trick is that radioactive carbon is continually replenished in a complex reaction that involves high-energy cosmic rays striking the upper atmosphere. In this process, nitrogen 7 protons and 7 neutrons gains a neutron and loses a proton, producing carbon 6 protons and 8 neutrons.

A folio from this codex was radiocarbon dated under the auspices of the Corpus Coranicum project. Hans-Caspar Graf von Bothmer from the University of Saarland, Germany, studied this manuscript in great detail from the point of view of script, ornamentation and illumination.

This monumental Qur'anic manuscript originally had dimensions around 51 cm in length by 47 cm in width Figure Its origin appears to be from Syria. However, the radiocarbon dating of this manuscript suggests a date between and CE. Certain features of the manuscript and the iconography intimate that this work was made for a member of the Umayyad family; historical circumstances suggest that caliph al-Walid himself may have commissioned it. However, the carbon dating points to a slightly earlier date.

Here it is interesting to note that both the palaeographic considerations and radiocarbon dating have arrived at nearly the same conclusion, i. However, as von Bothmer has noted, the radiocarbon dating gives a slightly earlier date. This could be due to the fact that the radiocarbon dating gives the death of animal and not when the manuscript was actually written.

The most famous of them is the Chester Beatty Moritz published details of the twenty ornamented pages. Late in the 19th century the manuscript was in St. Petersburg, Russia, where it was studied by the Russian orientalist A. So great was the interest in this codex that in Pisarev or Pissareff was encouraged to publish a facsimile edition.

Table I below provides a summary of radiocarbon dated manuscripts of the Qur'an that have been described and fully referenced in the previous section.

Some manuscripts were dated several times to understand the accuracy of the process as well as to presumably check the laboratory-dependent changes in dating that may be observed. Also added are the combined dating of the folios which were analyzed in the same lab, and belonging to the same codex. One may observe that a few of the reported dates differ slightly from their original publications.

Where possible, for older results, we have made use of the latest calibration curve IntCal13 and accompanying radiocarbon calibration and analysis software, OxCal 4. Table I: List of radiocarbon dated manuscripts of Qur'an. As shown in Table I, it has been radiocarbon-dated in five different labs in five different countries. This also serves as a platform to independently verify the agreement on dating performed in various laboratories. Agreement between independent radiocarbon tests conducted at different laboratories is a very useful method for weeding out aberrations due to mishandling of samples.

One may conclude that the radiocarbon tests completed at Lyon are suspect due to their irreproducibility. The application of radiocarbon dating to early Qur'ans has also resulted in a raft of questionable, bizarre and even absurd hypotheses from non-scientists. It seems that such attempts are to anchor their own chronological reconstruction of history or, by corollary, the construction of "new science" to validate their hypotheses.

We will examine some of these prominent hypotheses below. Being well served by historians, is Qur'anic studies really in need of carbon dating? After all there are some major drawbacks to this method - it has a monetary cost and involves the destruction of a small sample of the artefact in question. Other serious issues include the wide range of calendar years in which a manuscript could have been written.

Scholars have successfully utilised traditional dating methods such as palaeography, codicology and art history that utilise script, format, ornamentation and illumination which are then compared, where possible, with their dated counterparts in architecture.

In short, why bother? Being a modern invention, some historians have perhaps become unduly skeptical in embracing radiocarbon dating. Two Qur'ans, both with endowment notices, were carbon dated by the Centre de Datation par le Radiocarbone de Lyon, France, and provided a range of dates that preceded the date given in the endowment notices by around 50 and years, respectively.

It is also important to remember that the carbon dating of parchment is an imprecise science something indicated by the large range of possible dates given for the various fragments. An imprecise science does not follow the scientific method - the method that involves testing an idea and modifying the idea to fit the evidence.

Radiocarbon dating utilizes the knowledge of the unstable nature of 14 C with a precise half-life that makes it easy to measure, thus making it an absolute dating method. As a test, in , Willard Libby and his team took samples of acacia from two ancient Egyptian Old Kingdom rulers and dated them. Therefore, it is clear that radiocarbon dating is not based on some imprecise science, cooking up evidence to fit the idea or data.

On the other hand, palaeography is a relative dating method which gives an order of events without giving an exact age. Thus, generally speaking, it cannot be used to pinpoint dates with high precision. Is palaeography a form of science? Commenting on the issues regarding the dating of ancient Hebrew inscriptions, William M. Schniedewind says:. The so-called science of paleography often relies on circular reasoning because there is insufficient data to draw precise conclusion about dating.

Scholars also tend to oversimplify diachronic development, assuming models of simplicity rather than complexity. In other words, palaeography can at best be termed as an inexact science, filled with uncertainties and imprecisions.

It is not judicious to upscale palaeography for its reliability whilst, on the other hand, putting down radiocarbon dating for its alleged lack thereof. So, what is the general "rule of thumb" followed in dating manuscripts via palaeography? This kind of precision dating defies the realities of scribal activity. The productive writing life of a scribe was probably around thirty or thirty-five years. Add to that the fact that the scribal profession was an apprenticed trade, with students learning a particular style from a teacher, and we find that a given hand may be present over multiple generations of scribes.

Thus the "rule of thumb" should probably be to avoid dating a hand more precisely than a range of at least seventy or eighty years. This is comparable with the "rule of thumb" of at least a range of 70 to 80 years used in palaeography for dating a manuscript. Unlike radiocarbon dating, it is worth noting that a range of 70 to 80 years used in palaeography has no confidence level attached to it. The choice of whether to believe in such a "confidence level" is entirely up to an individual.

In any case, the Birmingham results suggest that Lyon might not have botched the job after all. Intriguingly, the first date range from Lyon — corresponds rather closely to the date range given from a laboratory in Oxford for the Birmingham manuscript — What is telling here is the fact that Reynolds, instead of using a scientific approach to look at the problem, applies his own reasoning that must necessarily accord with his preferred historical interpretation.

How does one make a rational choice as to which date, if any, out of these three is correct? The answer is that there is no way of knowing if Lyon botched the job unless these three dates are independently compared with those obtained from other labs. Reynolds makes no attempt to use the scientific method here.

He says,. Nevertheless, the dating of these manuscripts has proven to be highly problematic and controversial. Suffice to say that the process of radiocarbon dating does not seem to be working accurately on these materials. For instance, one such manuscript, now in Birmingham, England, has been given a date range that places it before Muhammad began his religious movement.

It is not clear why the radiocarbon dating of these manuscripts is inaccurate. Furthermore, how does Shoemaker know that the dating is inaccurate? He has not published any independent, consistent, and reliable radiocarbon data for each of these manuscripts that could substantiate his claim. It is worthwhile pointing out that when applied to parchments in fields other than Qur'anic studies, radiocarbon dating has yielded results that are "generally Here the problem may lie with the conditions arid or semi-arid climate under which the cattle, the hides of which were later turned into parchment, was raised.

Thus, according to his view, the arid or semi-arid climate in which the parchment for Qur'anic manuscripts were produced does not lend itself to accurate radiocarbon dating. There are numerous problems with this view. As we had noted earlier, radiocarbon 14 C is produced via the cosmogenic process and this happens at stratospheric altitudes of 9 to 15 km above the surface of the Earth.

In general, the cosmic rays flux remains constant and observed fluctuations in production rate of 14 C are controlled by geomagnetic field strength and solar activity. Thus seasonal changes and presence of moisture on the surface of the Earth have no effect on the production rate of 14 C.

What about the variation of decay of radiocarbon 14 C due to the chemical environment around the atom? Thus, the variation of just a percentage or so, is much too small to affect Earth's overall time scale and consequently the radiocarbon dating itself. If one were to instead use the data from the southern hemisphere and we are talking about Arabia here , I am told by those more expert in this procedure than me that very different datings would result. To begin with, Arabia is not in the Southern Hemisphere.

It is situated in the Northern Hemisphere between the latitudes The Tropic of Cancer at As for the global atmospheric radiocarbon content, it is controlled by several factors such as climatic changes, oceanic circulation, solar output and geomagnetic variability. It has been demonstrated that Southern Hemisphere samples have lower 14 C contents. The question now is how much older are the radiocarbon samples from the Southern Hemisphere compared to the Northern Hemisphere? Furthermore, it is not surprising that the calibration data set for the Northern Hemisphere IntCal series [] is different from that of the Sourthern Hemisphere SHCal series , [] and that these are frequently updated to fine tune the respective calibration curves.

That is, these manuscripts are from the 1st century of hijra. Shoemaker's argument against radiocarbon dating shifts from raising the inter-hemispheric offset to intra-hemispheric changes in radiocarbon content. The problem, it would seem, is that radiocarbon dating in the medieval period is only accurate when it can be calibrated by tree ring data, particularly from oak trees. Such data is wanting for the medieval Mediterranean or Near East, and the data from the northern hemisphere that has been used to calibrate these tests was taken from Ireland and North America.

There are several inaccuracies in the above statements. The work of the Aegean Dendrochronology Project started in s and since then it has continued since to build the long tree-ring chronologies for the eastern half of the Mediterranean.

Its aim was to make scientific sense of the Aegean and Near Eastern chronology from the Neolithic Age to the present. The most recent state as of late of the Aegean tree-ring chronology is shown in Figure 23 which also appeared in a slightly expanded form in Figure The state of Aegean tree-ring chronologies as of late This is an update of the bar graph published in Less common species such as boxwood and yew are removed in this plot.

Source: Aegean Dendrochronology Project. Now that we have established the fact that the dendrochronological data from oak trees among others already exist, let us now look into the issue of calibration. Shoemaker says that since the calibration is done using the tree-ring data from Ireland and North America, it can't be trusted for dating medieval Mediterranean and Near East samples.

The tacit assumption of his claim is that the chronology derived from the tree-ring data from Ireland and North America is very different from what is obtained from the Mediterranean and Near East samples. One of the fundamental tenets of radiocarbon dating is that within each hemisphere there was sufficient mixing of the pre-industrial atmosphere to allow the use of a universal 14 C calibration dataset. On the issue of calibration, it must be mentioned that the dendrochronological database for the IntCal04 curve is largely similar to the dataset of the IntCal98 curve, but also includes new measurements for the Iron Age period, for example, German Oak samples run for the East Mediterranean Radiocarbon Comparison Project.

A trial run of the model against the IntCal04 calibration curve gave essentially similar results, albeit that the dates become slightly older. Reynolds, on the other hand, claimed that the dating of Dead Sea Scrolls may be considered more accurate than the dating of manuscripts of Qur'an. His reasoning is as follows:. This allows scientists to calibrate their measurements more precisely.

This is entirely erroneous. The tree ring atmospheric radiocarbon calibration data set spanning 0 to 12, years BP is used Figure It is superior to all other atmospheric radiocarbon calibration data due to the number and quality of the radiocarbon measurements and the accuracy and precision of the tree dendrochronology. Figure Schematic diagram of IntCal04 and Marine04 calibration data set construction.

The IntCal09 uses a similar data set. The scrap of linen and piece of leather are dated using the standard calibration data set. It appears that Reynolds does not properly comprehend how radiocarbon calibration curves are constructed.

Strained, arbitrary and impossible interpretations of science, in our case of the science of radiocarbon dating, can lead to endless possibilities, i. We have already seen specific examples in the above sub-sections. Here we are going to deal with historical constructions or possibilities that are a result of interpretations of radiocarbon dating, more specifically of the Mingana folios at Birmingham.

Parchment was an expensive material the skin of the entire animal was used to produce the big folio. These stocks became part of the loot captured by the Arabs in the first years of the conquest. To test this hypothesis, it is necessary to reread the existing historical sources dedicated to the first years of the Arab conquests.

In essence, one is asked to believe in the fantastic hypothesis that the people of Greater Syria among other places stocked already prepared blank parchment and were eagerly awaiting the advent of Islam and Arab conquests in order to hand them willingly this valuable possession. One is led to believe unused parchment had been left for years!

Why would the seller s expend an enormous amount of time, money and effort to prepare a multitude of blank parchment with no customer or no prospect of a customer? This in itself is self-contradictory and it assumes a thriving market. Additionally, if a client could afford to have such a codex constructed, why would one rely on parchment that is years or generations old? Rich patrons presumably could afford brand new parchment, given the likely deterioration of prepared stocked parchment that is over half a century in age.

Did the new rulers and their subjects need recourse to stocked parchment? As far as we are aware there are no examples from early Islamic history where the Muslims were unable to execute a writing project because of the lack of prepared stocked parchment. Common sense dictates if the Muslims desperately needed parchment to write on, they could have simply requested already used parchment, religious or otherwise, scraped it clean and started writing.

All of the preceding assumes the existence and logical necessity of prepared stocked parchment that is years old. Rezvan cites no historical sources supportive of his hypothesis, and, as far as we are aware, there is no recorded instance around the time of late antiquity of prepared blank parchment being deliberately stored for such an extensive period of time.

Unfortunately, his misunderstanding of the radiocarbon date range has resulted in him adopting an ad hoc randomly generated number range to satisfy his hypothesis retrospectively. He concludes,. Reynolds has expended a not inconsiderate amount of effort explaining, identifying and at times advocating John Wansbrough's theories, [] including Wansbrough's now abandoned theory of a late compilation of the Qur'an. There is not the slightest hint of historical context that necessitates the wholesale re-writing of the Late Antiquity, including nascent religious movements, inter-religious dynamics, Arabic palaeography, codicology, scribal culture and book culture.

This kind of irresponsible flip-flopping is unlikely to benefit the field of Qur'anic studies and leaves the author's stated position on this most important issue confused and uncertain. There is an important methodological principle to be observed here. Arabe a and Ms. With the benefit of further examination and additional evidence, he has since revised his views and now considers them as emanating from the same manuscript. One must be very careful not to make assumptions and generalisations on the basis of a few tests.

As described in the previous section, sample pretreatment is absolutely critical if one wants to obtain the most accurate measurements. Who then should have the final say in matters relating to dating? It may seem what is at stake here is the historian's craft. Spending decades honing skills learnt from masters in the field, it is only natural to encounter some pushback against a recently developed detached scientific method, especially when it appears to undermine commonly accepted historical paradigms.

However, there need not be any confrontation. One of the great benefits and advantages of radiocarbon dating is that scholarly prejudice and pre-suppositions about the genesis of Arabic scripts and Qur'anic manuscripts are not factored into the calculation. It cannot, however, be seen as disadvantageous or faulty when it appears to clash with one's own chronological reconstruction.

A collaborative approach that makes full use of scientific tests whilst remaining anchored in time tested traditional historical methods is more likely to provide the most fruitful results. The invention of radiocarbon dating has been revolutionary for the humanities. Nevertheless, one of the downsides are the potential large time intervals which do not prove very useful in dating manuscripts very precisely, though this has been mitigated somewhat by the year on year improvement in accuracy and precision.

At the outset when this technique was being considered for application to the Qur'an, specialists were rightly cautious and skeptical regarding the usefulness of the expected results. Writing in , Gerd-R. Puin pointed out radiocarbon dating had results scattered over a large time period, sometimes spanning a few hundred years.

He suggested the traditional methods of Arabic palaeography were more precise and offered a smaller range for dating Qur'anic manuscripts. Since then much progress has been made in the intervening thirty-five years. One can take a positive view of the science and see in the interpretation of its results an avenue of further enquiry into the examination of Islamic origins. Radiocarbon dating was not developed as a tool to advance the traditional account of the compilation and transmission of the Qur'an, though this is the impression one may be left with reading certain scholarly articles and popular level works written by scholars.

Faulty understanding of the scientific principles underpinning this radiometric dating technique have caused some modern scholars working in Islamic Studies to imagine improbable and sometimes absurd hypotheses. Some seem to suggest the wholesale dismissal of this technique. Others that this technique doesn't work for the Qur'an. Key terms and concepts such as probability, accuracy and precision are found to be poorly understood.

A common feature of the aforementioned criticisms, at present without exception, is the absence of any peer reviewed scientific literature supportive of such views. Instead recourse is made to informal scientific conversation occasionally referencing unnamed persons.

Some of the discussion seems strained to coincide with the authors preferred historical reconstruction. Our investigation points to the fact that even though the palaeographic and radiocarbon results usually match each other, the scientific method of radiocarbon dating can assist in generating and informing the debate regarding the chronology of Qur'anic manuscripts.

In fact, more than thirty-five years ago similar conclusions were reached for the Dead Sea Scrolls using radiocarbon and palaeographic datings. The radiocarbon method can only supplement, and at times complement, the traditional method of palaeography and is gaining prominence in dating.

As the accuracy and precision of radiocarbon dating improves with every passing year, one would be wise to take heed of Blair's insistence on utilising a more comprehensive approach than is currently the case, insisting that the adoption of multi-disciplinary sophistication will help to solve the disputes on dating early Qur'anic manuscripts.
