Artificial cranial deformation
Artificial cranial deformation, head flattening, or head binding is a form of body alteration in which the skull of a human being is intentionally deformed. It is done by distorting the normal growth of a child's skull by applying force. Flat shapes, elongated ones (produced by binding between two pieces of wood), rounded ones (binding in cloth) and conical ones are among those chosen. It is typically carried out on an infant, as the skull is most pliable at this time. In a typical case, headbinding begins approximately a month after birth and continues for about six months.
Intentional cranial deformation was once commonly practised in a number of cultures widely separated geographically and chronologically and still occurs today in a few places, like Vanuatu.
Intentional human cranial deformation is believed to predate written history. The earliest suggested examples include the Proto-Neolithic Homo sapiens component (9th millennium BC) from Shanidar Cave in Iraq and also among Neolithic peoples in Southwest Asia. Originally, the Neanderthal skulls found in the Neanderthal component of Shanidar Cave were believed to have been artificially deformed representing the oldest example of such practices by tens of thousands of years, but this later proved to be incorrect. The cranial remains of specimen Shanidar 5 were newly reconstructed in 1999 by the anthropology team of Chech, Grove, Thorne, and Trinkaus where it was discovered the original reconstruction of the skull was in error. As a result the team concluded "we no longer consider that artificial cranial deformation can be inferred for the specimen".
In the Old World, Huns and Alans are also known to have practised similar cranial deformation. In Late Antiquity (AD 300-600), the East Germanic tribes who were ruled by the Huns, adopted this custom (Gepids, Ostrogoths, Heruli, Rugii and Burgundians). In western Germanic tribes, artificial skull deformations have rarely been found.
In the Americas the Maya, Inca, and certain tribes of North American natives performed the custom. In North America the practice was especially known among the Chinookan tribes of the Northwest and the Choctaw of the Southeast. The Native American group known as the Flathead did not in fact practise head flattening, but were named as such in contrast to other Salishan people who used skull modification to make the head appear rounder. However, other tribes, including the Choctaw, Chehalis, and Nooksack Indians, did practise head flattening by strapping the infant's head to a cradleboard. The Lucayan people of the Bahamas practised it. The practice was also known among the Australian Aborigines.
Friedrich Ratzel in The History of Mankind reported in 1896 that deformation of the skull, both by flattening it behind and elongating it towards the vertex, was found in isolated instances in Tahiti, Samoa, Hawaii, and the Paumotu group and occurring most frequently on Mallicollo in the New Hebrides (today Malakula, Vanuatu), where the skull was squeezed extraordinarily flat.
In the region of Toulouse (France), these cranial deformations persisted sporadically up until the early twentieth century; however, rather than being intentionally produced as with some earlier European cultures, Toulousian Deformation seemed to have been the unwanted result of an ancient medical practice among the French peasantry known as bandeau, in which a baby's head was tightly wrapped and padded in order to protect it from impact and accident shortly after birth; in fact, many of the early modern observers of the deformation were recorded as pitying these peasant children, whom they believed to have been lowered in intelligence due to the persistence of old European customs.
Methods and types

Deformation usually begins just after birth for the next couple of years until the desired shape has been reached or the child rejects the apparatus (Dingwall, 1931; Trinkaus, 1982; Anton and Weinstein, 1999).
There is no established classification system of cranial deformations. Many scientists have developed their own classification systems, but they have not agreed on a single classification for all forms that are seen (Hoshower et al., 1995).
In Europe and Asia, three main types of artificial cranial deformation have been defined by E.V. Zhirov (1941, p. 82):
Cranial deformation was probably performed to signify group affiliation, or to demonstrate social status. This may have played a key role in Maya society. It could be aimed at creating a skull shape which is aesthetically more pleasing or associated with desirable attributes. For example, in the Nahai-speaking area of Tomman Island and the south south-western Malakulan (Australasia), a person with an elongated head is thought to be more intelligent, of higher status, and closer to the world of the spirits
Meanwhile, it is also possible that the practice of cranial deformation takes its origin in an attempt to emulate those groups of the population, in which elongated head shape was a natural condition. For example, Rivero and Tschudi in “Peruvian Antiquities” (1851/1853) describe a mummy containing a foetus with an elongated skull.
...the same formation [i.e. absence of the signs of artificial pressure] of the head presents itself in children yet unborn; and of this truth we have had convincing proof in the sight of a foetus, enclosed in the womb of a mummy of a pregnant woman, which we found in a cave of Huichay, two leagues from Tarma, and which is, at this moment, in our collection. Professor D’Outrepont, of great Celebrity in the department of obstetrics, has assured us that the foetus is one of seven months’ age. It belongs, according to a very clearly defined formation of the cranium, to the tribe of the Huancas. We present the reader with a drawing of this conclusive and interesting proof in opposition to the advocates of mechanical action as the sole and exclusive cause of the phrenological form of the Peruvian race.
Dr. Bellamy makes a similar observation about the two elongated skulls of infants, which were discovered and brought to England by Captain Blankley and handed over to the Museum of the Devon and Cornwall Natural History Society in 1838. According to Bellamy these skulls belonged to two infants – male and female, "one of which was not more than a few months old, and the other could not be much more than one year”. He writes,
It will be manifest from the general contour of these skulls that they are allied to those in the Museum of the College of Surgeons in London, denominated Titicacans. Those adult skulls are very generally considered to be distorted by the effects of pressure; but in opposition to this opinion Dr. Graves has stated, that “a careful examination of them has convinced him that their peculiar shape cannot be owing to artificial pressure;” and to corroborate this view, we may remark that the peculiarities are as great in the child as in the adult, and indeed more in the younger than in the elder of the two specimens now produced: and the position is considerably strengthened by the great relative length of the large bones of the cranium; by the direction of the plane of the occipital bone, which is not forced upwards, but occupies a place in the under part of the skull; by the further absence of marks of pressure, there being no elevation of the vertex nor projection of either side; and by the fact of there being no instrument nor mechanical contrivance suited to produce such an alteration of form (as these skulls present) found in connexion with them.
Similarly Pentland writes about adult skulls which he excavated near Lake Titicaca in Bolivia in 1827:
A careful examination of these skulls has convinced me that their peculiar shape cannot be owing to artificial pressure. The great elongation of the face and the direction of the plane of the occipital bone are not to be reconciled with this opinion, and therefore we must conclude that the peculiarity of shape depends on a natural conformation. If this view of the subject be correct, it follows that these skulls belonged to a race of mankind now extinct, and which differed from any now existing.

There is no statistically significant difference in cranial capacity between artificially deformed skulls and normal skulls in Peruvian samples.
