Crystal skull

Research

Many crystal skulls are claimed to be pre-Columbian, usually attributed to the Aztec or Maya civilizations. Mesoamerican art has numerous representations of skulls, but none of the skulls in museum collections come from documented excavations. Research carried out on several crystal skulls at the British Museum in 1967, 1996 and 2004 shows that the indented lines marking the teeth (for these skulls had no separate jawbone, unlike the Mitchell-Hedges skull) were carved using jeweler's equipment (rotary tools) developed in the 19th century, making a pre-Columbian origin untenable.

The type of crystal used for these skulls was identified by examination of chlorite inclusions. It is only found in Madagascar and Brazil, and thus unobtainable or unknown within pre-Columbian Mesoamerica. The study concluded that the skulls were crafted in the 19th century in Germany, quite likely at workshops in the town of Idar-Oberstein, which was renowned for crafting objects made from imported Brazilian quartz in the late 19th century.

It has been established that the crystal skulls in the British Museum and Paris's Musée de l'Homme were originally sold by the French antiquities dealer Eugène Boban, who was operating in Mexico City between 1860 and 1880. The British Museum crystal skull transited through New York's Tiffany & Co., while the Musée de l'Homme's crystal skull was donated by Alphonse Pinart, an ethnographer who had bought it from Boban.

In 1992, the Smithsonian Institution investigated a crystal skull provided by an anonymous source; the source claimed to have purchased it in Mexico City in 1960, and that it was of Aztec origin. The investigation concluded that this skull also was made recently. According to the Smithsonian, Boban acquired his crystal skulls from sources in Germany, aligning with conclusions made by the British Museum.

The Journal of Archaeological Science published a detailed study by the British Museum and the Smithsonian in May 2008. Using electron microscopy and X-ray crystallography, a team of British and American researchers found that the British Museum skull was worked with a harsh abrasive substance such as corundum or diamond, and shaped using a rotary disc tool made from some suitable metal. The Smithsonian specimen had been worked with a different abrasive, namely silicon carbide (carborundum), a silicon-carbon compound which is a synthetic substance manufactured using modern industrial techniques. Since the synthesis of carborundum dates only to the 1890s and its wider availability to the 20th century, the researchers concluded "[t]he suggestion is that it was made in the 1950s or later".

Individual skulls

British Museum skull

The crystal skull of the British Museum first appeared in 1881, in the shop of the Paris antiquarian, Eugène Boban. Its origin was not stated in his catalogue of the time. He is said to have tried to sell it to Mexico's national museum as an Aztec artifact, but was unsuccessful. Boban later moved his business to New York City, where the skull was sold to George H. Sisson. It was exhibited at the meeting of the American Association for the Advancement of Science in New York City in 1887 by George F. Kunz. It was sold at auction, and bought by Tiffany and Co., who later sold it at cost to the British Museum in 1897. This skull is very similar to the Mitchell-Hedges skull, although it is less detailed and does not have a movable lower jaw.

The British Museum catalogues the skull's provenance as "probably European, 19th century AD" and describes it as "not an authentic pre-Columbian artefact". It has been established that this skull was made with modern tools, and that it is not authentic.

Mitchell-Hedges skull

Perhaps the most famous and enigmatic skull was allegedly discovered in 1924 by Anna Mitchell-Hedges, adopted daughter of British adventurer and popular author F. A. Mitchell-Hedges. It is the subject of a video documentary made in 1990, Crystal Skull of Lubaantun. It was examined and described by Smithsonian researchers as "very nearly a replica of the British Museum skull – almost exactly the same shape, but with more detailed modeling of the eyes and the teeth".

Mitchell-Hedges claimed that she found the skull buried under a collapsed altar inside a temple in Lubaantun, in British Honduras, now Belize. As far as can be ascertained, F.A. Mitchell-Hedges himself made no mention of the alleged discovery in any of his writings on Lubaantun. Others present at the time of the excavation recorded neither the skull's discovery nor Anna's presence at the dig. Recent evidence has come to light showing that F.A. Mitchell-Hedges purchased the skull at a Sotheby's auction in London on 15 October 1943, from London art dealer Sydney Burney. In December 1943, F. A. Mitchell-Hedges disclosed his purchase of the skull in a letter to his brother, stating plainly that he acquired it from Burney.

The skull is made from a block of clear quartz about the size of a small human cranium, measuring some 5 inches (13 cm) high, 7 inches (18 cm) long and 5 inches (13 cm) wide. The lower jaw is detached. In the early 1970s, it came under the temporary care of freelance art restorer Frank Dorland, who claimed, upon inspecting it, that it had been "carved" with total disregard to the natural crystal axis, and without the use of metal tools. Dorland reported being unable to find any tell-tale scratch marks, except for traces of mechanical grinding on the teeth, and he speculated that it was first chiseled into rough form, probably using diamonds, and the finer shaping, grinding and polishing was achieved through the use of sand over a period of 150 to 300 years. He said it could be up to 12,000 years old. Although various claims have been made over the years regarding the skull's physical properties, such as an allegedly constant temperature of 70 °F (21 °C), Dorland reported that there was no difference in properties between it and other natural quartz crystals.

While in Dorland's care, the skull came to the attention of writer Richard Garvin, at the time working at an advertising agency where he supervised Hewlett-Packard's advertising account. Garvin made arrangements for the skull to be examined at Hewlett-Packard's crystal laboratories in Santa Clara, California, where it was subjected to several tests. The labs determined only that it was not a composite as Dorland had supposed, but that it was fashioned from a single crystal of quartz. The laboratory test also established that the lower jaw had been fashioned from the same left-handed growing crystal as the rest of the skull. No investigation was made by Hewlett-Packard as to its method of manufacture or dating.

As well as the traces of mechanical grinding on the teeth noted by Dorland, Mayanist archaeologist Norman Hammond reported that the holes (presumed to be intended for support pegs) showed signs of being made by drilling with metal. Anna Mitchell-Hedges refused subsequent requests to submit the skull for further scientific testing.

The earliest published reference to the skull is the July 1936 issue of the British anthropological journal Man, where it is described as being in the possession of Sydney Burney, a London art dealer who was said to have owned it since 1933, and from whom evidence suggests F.A. Mitchell-Hedges purchased it.

F. A. Mitchell-Hedges mentioned the skull only briefly in the first edition of his autobiography, Danger My Ally (1954), without specifying where or by whom it was found. He merely claimed that "it is at least 3,600 years old and according to legend it was used by the High Priest of the Maya when he was performing esoteric rites. It is said that when he willed death with the help of the skull, death invariably followed". All subsequent editions of Danger My Ally omitted mention of the skull entirely.

In a 1970 letter Anna also stated that she was "told by the few remaining Maya that the skull was used by the high priest to will death". For this reason, the artifact is sometimes referred to as "The Skull of Doom". Anna Mitchell-Hedges toured with the skull from 1967 exhibiting it on a pay-per-view basis. Somewhere between 1988 and 1990 she toured with the skull. She continued to grant interviews about the artifact until her death.

In her last eight years, Anna Mitchell-Hedges lived in Chesterton, Indiana, with Bill Homann, whom she married in 2002. She died on 11 April 2007. Since that time the Mitchell-Hedges Skull has been owned by Homann. He continues to believe in its mystical properties.

In November 2007, Homann took the skull to the office of anthropologist Jane MacLaren Walsh, in the Smithsonian's National Museum of Natural History for examination. Walsh carried out a detailed examination of the skull using ultraviolet light, a high-powered light microscope, and computerized tomography. Homann took the skull to the museum again in 2008 so it could be filmed for a Smithsonian Networks documentary, Legend of the Crystal Skull, and on this occasion, Walsh was able to take two sets of silicone molds of surface tool marks for scanning electron microscope (SEM) analysis. The SEM micrographs revealed evidence that the crystal had been worked with a high speed, hard metal rotary tool coated with a hard abrasive, such as diamond. Walsh's extensive research on artifacts from Mexico and Central America showed that pre-contact artisans carved stone by abrading the surface with stone or wooden tools, and in later pre-Columbian times, copper tools, in combination with a variety of abrasive sands or pulverized stone. These examinations led Walsh to the conclusion that the skull was probably carved in the 1930s, and was most likely based on the British Museum skull which had been exhibited fairly continuously from 1898.

In the National Geographic Channel documentary "The Truth Behind the Crystal Skulls", forensic artist Gloria Nusse performed a forensic facial reconstruction over a replica of the skull. According to Nusse, the resulting face had female and European characteristics. As it was hypothesized that the Crystal Skull was a replica of an actual human skull, the conclusion was that it could not have been created by ancient Americans.

Paris skull

The largest of the three skulls sold by Eugène Boban to Alphonse Pinart (sometimes called the Paris Skull), about 10 cm (4 in) high, has a hole drilled vertically through its center. It is part of a collection held at the Musée du Quai Branly, and was subjected to scientific tests carried out in 2007–08 by France's national Centre de recherche et de restauration des musées de France (Centre for Research and Restoration of the Museums in France, or C2RMF). After a series of analyses carried out over three months, C2RMF engineers concluded that it was "certainly not pre-Columbian, it shows traces of polishing and abrasion by modern tools". Particle accelerator tests also revealed occluded traces of water that were dated to the 19th century, and the Quai Branly released a statement that the tests "seem to indicate that it was made late in the 19th century".

In 2009 the C2RMF researchers published results of further investigations to establish when the Paris skull had been carved. Scanning electron microscopy (SEM) analysis indicated the use of lapidary machine tools in its carving. The results of a new dating technique known as quartz hydration dating (QHD) demonstrated that the Paris skull had been carved later than a reference quartz specimen artifact, known to have been cut in 1740. The researchers conclude that the SEM and QHD results combined with the skull's known provenance indicate it was carved in the 18th or 19th century.

Smithsonian Skull

The "Smithsonian Skull", Catalogue No. A562841-0 in the collections of the Department of Anthropology, National Museum of Natural History, was mailed to the Smithsonian Institution anonymously in 1992, and was claimed to be an Aztec object by its donor and was purportedly from the collection of Porfirio Diaz. It is the largest of the skulls, with a weight of 31 pounds (14 kg) and a height of 15 inches (38 cm). It was carved using carborundum, a modern abrasive. It has been displayed as a modern fake at the National Museum of Natural History.

Paranormal claims and spiritual associations

Some individuals believe in the paranormal claim that crystal skulls can produce a variety of miracles. Anna Mitchell-Hedges claimed that the skull she allegedly discovered could cause visions and cure cancer, that she once used its magical properties to kill a man, and that in another instance, she saw in it a premonition of the John F. Kennedy assassination.

In the 1931 play The Satin Slipper by Paul Claudel, King Philip II of Spain uses "a death's head made from a single piece of rock crystal", lit by "a ray of the setting sun", to see the defeat of the Spanish Armada in its attack on the Kingdom of England.

Claims of the healing and supernatural powers of crystal skulls have had no support in the scientific community, which has found no evidence of any unusual phenomena associated with the skulls nor any reason for further investigation, other than the confirmation of their provenance and method of manufacture.

Another novel and historically unfounded speculation ties in the legend of the crystal skulls with the completion of the previous Maya calendar b'ak'tun-cycle on 21 December 2012, claiming the re-uniting of the thirteen mystical skulls will forestall a catastrophe allegedly predicted or implied by the ending of this calendar (see 2012 phenomenon). An airing of this claim appeared (among an assortment of others made) in The Mystery of the Crystal Skulls, a 2008 program produced for the Sci Fi Channel in May and shown on Discovery Channel Canada in June. Interviewees included Richard Hoagland, who attempted to link the skulls and the Maya to life on Mars, and David Hatcher Childress, proponent of lost Atlantean civilizations and anti-gravity claims.

Crystal skulls are also referred to by author Drunvalo Melchizedek in his book Serpent of Light. He writes that he came across indigenous Mayan descendants in possession of crystal skulls at ceremonies at temples in the Yucatán, which he writes contained souls of ancient Mayans who had entered the skulls to await the time when their ancient knowledge would once again be required.

The alleged associations and origins of crystal skull mythology in Native American spiritual lore, as advanced by neoshamanic writers such as Jamie Sams, are similarly discounted. Instead, as Philip Jenkins notes, crystal skull mythology may be traced back to the "baroque legends" initially spread by F.A. Mitchell-Hedges, and then afterwards taken up:

By the 1970s, the crystal skulls [had] entered New Age mythology as potent relics of ancient Atlantis, and they even acquired a canonical number: there were exactly thirteen skulls.

None of this would have anything to do with North American Indian matters, if the skulls had not attracted the attention of some of the most active New Age writers.
