Abstract 

The Tomb of the Eagles is formally known as the Isbister Chambered Tomb. It is located north  of Scotland on the remote southeast coast of South Ronaldsay Island, one of the Orkney Islands.   The tomb was minimally excavated in 1958. When thoroughly excavated in 1975, a significant  collection of human remains, artifacts and animal bones was discovered. This study of the  Isbister remains summarizes the state of health enjoyed by the people who lived on this island  more than 4000 years ago. 



Introduction

The Neolithic period Tomb of the Eagles is officially identified as the Isbister Chambered Tomb.   It is located almost due north of John O’Groats and Duncansby Head in Scotland on the southeast  coast of South Ronaldsay Island, the southernmost major island in the Orkney archipelago  (Henshall, 1963).  In 1958, a minimal excavation of the tomb by Ronald Simison, owner of  the farmland, revealed many interesting objects.  His curiosity and diligence provided the impetus for a thorough excavation of this well-preserved burial place in 1976, and later restoration of the tomb in the following years (Hedges, 2000).  A significant amount of  information concerning the life and death of the Orkney people has been obtained from the  contents and construction of the tomb that archaeologists believe was constructed over 4000  years ago.  The Isbister tomb is one of seventy-six known chambered tombs in the Orkney  Islands (Fraser, 1983) that, together with stone houses, standing stone circles and monuments,  were built in the same period (Ritchie, 1978). 


Description of the Isbister Chambered Tomb 

The early people of the Orkneys built numerous structures that demonstrate an advanced  understanding of engineering, astronomy and mathematics (Thom, 1971). The spectacular setting  of the Isbister tomb is about 220 feet from the precipitous cliffs by the sea.  Its entrance overlooks the Pentland Firth that separates the northern coast of Scotland from the Orkney  Islands (Noonan, 2000). Archaeologists consider this chambered tomb to be one of the most  splendid found in the region and believe it gives evidence that they had great respect for the value  of life.  The rock structure has a sophisticated architectural design that required a great deal of skill and an intimate appreciation of building materials.  The design and placement of stones for  the doors, walls and roof required workers with exceptional talent, especially since it is assumed  that only primitive tools were available to move dirt and rock for site preparation and  construction of the tomb and retaining walls (Figure 1). 

A great flagstone forecourt surrounded the Isbister Tomb.  The exterior was oval-shaped with  more or less vertical walls that were 3.5 meters tall and a single entrance on the long wall closest  to the sea.  The floor area of the interior, including two small end chambers, was in the shape of a long rectangle about 8.33 X 1.45 meters; the height was around 3.5 meters (Figure 2).  The roof  was a sloping dome with the highest point in the center of the chamber.  Three small chambers  were built off the long sides of the chamber, two on the side opposite the entrance and one on the  long wall to the right of the entrance.  Two small chambers, each with a built-in stone shelf, were  located at either end of the long section of the chamber (Hedges, 2000). 

According to calibrated radiocarbon dates, construction of the Isbister Chambered Tomb began  in 3150 B.C. ( 80 years) and may have taken as much as two hundred years to complete.  This  date precedes construction of the pyramids of Egypt and is shortly after the recorded dispersion  of people groups from the City of Babel (The Bible, Genesis 11).  Archaeologists believe the  tomb was used regularly for 800 years, with the last burial around 1600 BC (Hedges, 2000).
 

Contents of the Isbister Chambered Tomb 

A limited excavation of the northern interior of the Isbister Chambered Tomb took place in 1958.  A number of human skulls and bones were removed from the tomb for safekeeping. A  photograph of this collection shows sixteen human skulls, six boxes that presumably contained  bones, a portion of a pelvis and four or five femurs.  Four small fragments of pottery were also  removed before the excavated area was filled with dirt (Hedges, 2000). 

In 1976, Ronald Simison initiated and completed an extensive excavation of the entire tomb.   An enormous amount of material was removed, including human bones, animal bones, shells,  fragments of pottery suitable for cooking, tools, seeds, necklace beads and a V-bored very highly  polished jet button (Figure 3) (Henshall, 1963).  Many talons and bones from white-tailed sea  eagles were found mixed with the human bones and so, the Isbister Chambered Tomb is also  called the Tomb of the Eagles. 

A remarkable finding concerning the bones in the tomb was the absence of intact skeletons.   Rather, piles of bones associated with a skull were arranged along the sides of the stalls (Figure  4).  In the side chambers, the floor was filled with skulls lying at all angles and mixed with bones  from other parts of the body.  In addition, the bones were bleached and weathered. This  arrangement and condition of bones made it obvious that the soft tissue of the deceased was  missing when the bones were brought into the tomb (Hedges, 1998).  This mortuary practice is  called excarnation, a custom that people groups around the world have practiced in various forms  for thousands of years (Renfrew, 1979). 

The human bones removed from the tomb were sent to Edinburgh for analysis by Judson T.  Chesterman, a retired surgeon working for the Department of Prehistory and Archaeology at the  University of Sheffield.  Including the remains obtained in 1958, there were 16,000 human bones  and fragments that required evaluation.  In 1981, Chesterman reported that bones of at least  342 individuals were recovered from the Isbister Chambered Tomb (Hedges, 2000).  This  investigator has also evaluated the human remains removed from other ancient burial sites in the  United Kingdom (Renfrew, 1979).

Even though the builders of the tombs, houses, villages and standing stones possessed advanced  engineering skills and an understanding of astronomy and mathematics, there is no evidence that  they had yet developed a written language. 


Evaluation of the Human Skeletal Remains 

The condition of the skulls and other bones removed from the Isbister Tomb were in a range  from intact and perfect, to incomplete fragments.  Presumably, this was the result of post-mortem  manipulation by the people who originally placed them in the tomb and the crushing weight of  earth and rocks intentionally placed over them at burial.  Additional damage to the remains may  have occurred during the removal process, in storage, or in transit to the examiner, Judson  Chesterman.  As a result, the accuracy of the evaluation may have been compromised to some  degree by the incomplete condition and damaged condition of the skulls and bones. 

The examination revealed that some skulls, mostly female, exhibited a markedly increased  attachment of the neck muscles to the back of the skull.  In these same instances, a visible  depression running laterally across the top of the cranium was noted.  These findings were interpreted to mean that both anomalies resulted from individuals carrying loads on their back  supported by a band over the head (Hedges, 2000). 

Elizabeth J. Glenn from Ball State University in Indiana independently studied the Isbister skulls.   In comparing these specimens to others from both the British Neolithic and Bronze Age, she  reported that the females had noticeably smaller heads than males, but that the males tended to  have longer heads anteroposteriorly than females.  She also concluded that these people would  have been visually distinguishable from those living further south in the British Isles, probably  the result of a slightly different genetic make-up in their ancestry (Hedges, 2000).   

Chesterman discovered a possibly inherited peculiarity on the articulating surfaces of the  occipital condyles (this and other  anatomical terms are defined in a glossary located at the end of this paper) with the atlas in the Isbister skulls. Each occipital condyle normally has only one facet and the occurrence of two facets on one or either side is highly unusual; evidence  of the normal distribution lies in a study of 585 skulls from different countries and periods that  describes only five instances of this unusual trait in 1,144 articulations. In contrast, thirty of  the occipital condyles showed two facets in the Isbister skulls, and one skull even exhibited a  triple facet. Thus, more than a third of the Isbister skulls demonstrated this rare anatomic  configuration.  (Hedges, 2000)

Another unusual occurrence in the Isbister remains was the precocious closure of the sutures of  the skull.  The normal distribution of this anatomic anomaly is about five in 10,000 births,  whereas there were six examples of this phenomenon in the meager number of Isbister skulls.  In  a related matter, degenerative spinal disease was diagnosed in at least 47% of the individuals and,  in one male believed to be 45–50 years of age, a 14-mm. thick skull exhibited asymmetry of the  foramen magnum. (Hedges, 2000) 

For the most part, the dentition of the remains seemed remarkably healthy.  Although the  occlusal surfaces of some teeth demonstrated extraordinary wear, dental caries was not a  common finding (Figure 5).  Out of 1537 teeth examined, only nine had deep carious lesions and  merely five posterior teeth exhibited periapical abscesses.  On the other hand, many mature  individuals showed minor to moderate generalized resorption of the alveolar bone, a finding  commonly associated with periodontal disease.  Even though the examination revealed impaction  of six third molars and three canine teeth, a greater than average absence of third molars was  noted in the specimens. The skull of a thirty-five year old female exhibited a palatal lesion  associated with a canine measuring 28 X 18 X 18-mm; it appeared to be benign, most probably a  cyst.  The shovel-shaped maxillary central incisor is a rare occurrence, but this anomaly was  identified in one out of seventy-seven skulls. Malpositioned or misaligned teeth were found in  some skulls and temporomandibular joint disorder was exhibited in three males and two females (Hedges, 2000). 

The large number of human bones in the tomb allows for a meaningful description of the size,  gender and age of these ancient people.  The average male was 5 feet 7 inches tall (range: 63 to  70 inches) whereas the average female was 5 feet 3 inches tall (range: 58 to 64 inches).  Both  genders appeared to have been muscular and an alteration in the bones of the ankle may have  been the result of scaling the surrounding cliffs from an early age.  Two percent of the  individuals suffered a broken bone at some stage in their life, but accidents appeared to be a  relatively minor cause of death since most of the broken bones were healed.  Out of the 179  teenagers and adults, 80 were male and 39 were female, while the gender of the 60 others could  not be determined.  Even though calculation of the age of human remains by examination of  bones and teeth is imprecise (biological rather than chronological), estimates of the 342  individuals buried in the tomb were as follows: 24 died before the age of two, 70 died between  two and twelve, 63 died as teenagers, 185 died as adults. And so, it is believed that few people in  the Isbister community lived to the age of fifty, that large numbers died at an early age, and that  the average life expectancy was around twenty years (Hedges, 2000). 

This review is based solely on the bones of 342 individuals who were buried in the Isbister  Chambered Tomb.  However, it is not believed to be the only burial place for people who lived  on this island during this time period. The physical characteristics of these other individuals and  how the bodies were treated are not known (Hedges, 2000). 


Conclusion 

The remains buried in the Isbister Chambered Tomb provide physical evidence of the people who  populated this area 4000 years ago. Their bones and teeth demonstrate the presence of health,  injury and disease.  Estimates of age indicate that their life span was much shorter than modern  day man. 

The quality of life experienced by these people is partially revealed by their ability to construct  substantial structures with primitive materials.  The extraordinary effort displayed in construction  of this tomb, and at least 75 other tombs in the Orkneys, gives ample proof that they had an  advanced understanding of engineering, astronomy and mathematics, and a great respect for the  value of life. Their artifacts also demonstrate a high level of expertise in the use of a drill to  perforate and polish hard rock into jet buttons, and the ability to make pottery in a manner that  allowed it to be used for cooking. 

Despite these advancements, there is no evidence that they possessed a written language.  This  should not be unexpected since most peoples of the same era (the dispersed people of Babel) also  had no recorded language skills.  In fact, the Isbister people could possibly be a part of this  dispersion. 

The human bones discovered in the Isbister Chambered Tomb reveal that these people  experienced energetic lives of health, but also encountered many of the injuries and diseases that  afflict contemporary society.
