Recent Survey of a Megalithic Stone Alignment at Byse
Recent Survey of a Megalithic Stone Alignment at Byse Srikumar M. Menon, Manipal School of Architecture and Planning, Manipal – 576 104 Mayank N. Vahia, Tata Institute of Fundamental Research, Mumbai and Manipal Advanced Research Group, Manipal University, Manipal – 576 104 Kailash Rao M., Manipal School of Architecture and Planning, Manipal – 576 104 Introduction: Megalithic monuments are found in profusion in peninsular India (Moorti 1994, 2008) and are generally ascribed to the south Indian Iron Age (Moorti 1994, 2008; Sundara 1975), though recent studies have indicated that megalith construction may well date back into the middle of the Neolithic in south India (Morrison 2005). The term megalith (lit. “built of large stones”) initially arose because of the variety of forms built with boulders or slabs of stone which characterized the monuments of this cultural trait that were noticed early on. Later, the definition was enlarged in scope to include even excavations in soft rock built by similar cultures in regions that lacked boulders and quarries for stone slabs. A large fraction of the megalithic monuments were burials or memorial in nature, such as cist or chamber burials and dolmens, but several other monuments like stone alignments defy the archaeological imagination as to what their purpose could have been. Moorti (1994, 2008) has classified megaliths into sepulchral and non- sepulchral, based on whether or not human remains have been associated with them or not, with sub-divisions based on the form and construction of the monuments. However, this classification is not exactly watertight, with megaliths like menhirs (single standing stone, whether undressed boulder or quarried slab) taking on sepulchral connotations in present-day Kerala region whereas they are essentially non-sepulchral in Karnataka.

The importance of human images in the development of Iberian megalithic art supports an evolution of these contents toward pieces with engraved weapons which dating back to the 3rd millennium cal BC. From the analysis of the evidences reported by the whole geographical sector, this paper is also aimed at determining if the graphic resources used in these stelae express any kind of identity. Visible stelae in barrows and chambers from the 3rd millennium cal BC would be the images around which sepulchral areas were progressively added, thus constituting true ancestral references throughout the Bronze Age.

Neolithic Farmers in Poland - a Study of Stable Isotopes in Human Bones and Teeth from Kichary Nowe in the South of Poland
Neolithic farmers in Poland - A study of stable isotopes in human bones and teeth from Kichary Nowe in the south of Poland Master thesis in archaeological science Archaeological Research Laboratory Stockholm University Supervisors: Kerstin Lidén and Gunilla Eriksson Author: Staffan Lundmark Cover photo: Mandible from the Kichary Nowe site, photo taken by the author Abstract: The diet of the Stone Age cultures is a strong indicator to the social group, thus farmers and hunters can be distinguished through their diet. There is well-preserved and well excavated Polish skeletal material available for such a study but the material has not previously been subject to stable isotopes analyses and therefore the questions of diets has not been answered. This study aims to contribute to the understanding of the cultures in the Kichary Nowe 2 area in the Lesser Poland district in southern Poland. Through analysis of the stable isotopes of Carbon, Nitrogen and Sulphur in the collagen of teeth and skeletal bones from the humans in the Kichary Nowe 2 grave-field and from bones from the fauna, coeval and from the same area, the study will establish whether there were any sharp changes of diets. The material from the grave-field comes from cultures with an established agricultural economy, where their cultural belonging has been anticipated from the burial context. The results from my study of stable isotopes from the bone material will be grouped by various parameters, culture, attribution to sex and age. The groups will then be compared to each other to investigate patterns within and between the groups.

"Megalithic Culture" of South India Is Represented by Burials of Considerable Variety
183 CHAPTER- V PART A: TYPOLOGY The so-called "megalithic culture" of South India is represented by burials of considerable variety. Though the term "megalithic" as applied to this burial complex is inadequate because many structures such as dolmens or cists not even associated with burials are grouped under this term; and some urn and sarcophagus burials unassociated with stone structures qualified as 1 "megalithic" • Again the term "megalithic" is applied to all settlements which yield pottery and iron tools normally found in megalithic burials irrespective of whether these settlements or associated with burials or not. It would I think, be useful to consider a broad definition of the term "megalithic" i.e., as a socio-religious expression of burying the deceased in cemeteries, in graves (which would include primary, secondary and symbolic burial) which may or may not have lithic appendage. One should also note here that the use of iron broadly coincides with this period and forms an "adjunct of this culture" (Moorti 1994 : 1). Therefore some archaeologists prefer to use the term "iron age culture" instead of "megalithic culture". So far as the typological classification of megaliths in India are concerned the attempts of Wheeler (1948) and Krishnaswami (1949 : 35-45) are noteworthy. Later, Leshnik (1974 : 226-227), Agrawal (1982 : 226-227) and Allchins (1983 : 331-33) recognize five basic types of burials i.e., pit burials, urn and sarcophagi burials, rock cut burial cham hers, cist burials and stone alignments. Dikshit and Sundara include many more types like dolmen, menhir, to pi kal and kudai kal.

Tokyo, National Astronomical Observatory of Japan. Pp. xx-xx. MEGALITHIC ASTRONOMY IN SOUTH INDIA Srikumar M. MENON Faculty of Architecture, Manipal Institute of Technology, Manipal – 576104, Karnataka, India. E-mail: [email protected] and Mayank N. VAHIA Tata Institute of Fundamental Research, Mumbai, India, and Manipal Advanced Research Group, Manipal University, Manipal – 576104, Karnataka, India. E-mail: [email protected] Abstract: The megalithic monuments of peninsular India, believed to have been erected in the Iron Age (1500BC – 200AD), can be broadly categorized into sepulchral and non-sepulchral in purpose. Though a lot of work has gone into the study of these monuments since Babington first reported megaliths in India in 1823, not much is understood about the knowledge systems extant in the period when these were built – in science and engineering, and especially in mathematics and astronomy. We take a brief look at the archaeological understanding of megaliths, before making a detailed assessment of a group of megaliths in the south Canara region of Karnataka State in South India that were hitherto assumed to be haphazard clusters of menhirs. Our surveys have indicated that there is a positive correlation of sight-lines with sunrise and sunset points on the horizon for both summer and winter solstices. We identify five such monuments in the region and present the survey results for one of these sites, demonstrating their astronomical implications. We also discuss the possible use of megaliths in the form of stone alignments/ avenues as calendar devices.

The Earliest Stone Monuments: Replication of Megalithic Structures at NIAS
The Earliest Stone Monuments: replication of megalithic structures at NIAS Srikumar M. Menon Many of you might have been mystified, or even shocked (quite justifiably!) over the last several days when certain mysterious aggregations of boulders made their appearance at certain locations on the NIAS campus. While pleading guilty of this sacrilege, I want to convey briefly the philosophy behind these structures. In a nutshell, these structures replicate megalithic structures, which are prehistoric monuments believed to have been erected in the Iron Age in the Indian subcontinent (roughly 1500BCE – 500BCE). Megaliths are found all over the world and in India, they are densely concentrated in the southern part of the subcontinent. Most megaliths are memorials, though a few types defy an understanding of the purposes for which they were erected. What is certain, however, is that megaliths represent the oldest surviving monuments in stone that we can encounter today. The structure near the lily pool (below) is a crude dolmen – a heavy “capstone” erected over three smaller boulders. There is also a single standing stone, known as menhir, nearby. Fig 2 shows a prehistoric dolmen that resembles this structure. 1 A dolmen and menhir near the lily pool at NIAS The structure in front of the car porch (top) is a dolmen too – slightly more elaborate, wherein three stones are arranged to make a small chamber with a horizontal capstone covering this arrangement. There is a boulder circle surrounding the dolmen, with two vertical stones forming a sort of portal giving entry to the structure. A prehistoric dolmen that resembles this is shown in Fig.

Megalith Quarries for Stonehenge's Bluestones
Megalith quarries for Stonehenge’s bluestones Mike Parker Pearson1,*, Josh Pollard2, Colin Richards3, Kate Welham4, Chris Casswell5, Charles French6, Duncan Schlee7, Dave Shaw8, Research Ellen Simmons9, Adam Stanford10, Richard Bevins11 & Rob Ixer1 Geologists and archaeologists have long known that the bluestones of Stonehenge came from the Preseli Hills of west Wales, 230km away, but only recently have some of their exact geo- logical sources been identiﬁed. Two of these quarries—Carn Goedog and Craig Rhos-y- felin—have now been excavated to reveal evi- dence of megalith quarrying around 3000 BC —the same period as the ﬁrst stage of the con- struction of Stonehenge. The authors present evidence for the extraction of the stone pillars and consider how they were transported, including the possibility that they were erected in a temporary monument close to the quar- ries, before completing their journey to Stonehenge.

Prehistoric Western Art 40,000 – 2,000 BCE
Prehistoric Western Art 40,000 – 2,000 BCE Introduction Prehistoric Europe was an evolving melting pot of developing cultures driven by the arrival of Homo sapiens, migrating from Africa by way of southwest Asia. Mixing and mingling of numerous cultures over the Upper Paleolithic, Mesolithic and Neolithic periods in Europe stimulated the emergence of innovative advancements in farming, food preparation, animal domestication, community development, religious traditions and the arts. This report tracks European cultural developments over these prehistoric periods, Figure 1 Europe and the Near East emphasizing each period’s (adapted from Janson’s History of Art, 8th Edition) evolving demographic effects on art development. Then, representative arts of the periods are reviewed by genre, instead of cultural or timeline sequence, in order to better appreciate their commonalities and differences. Appendices identify Homo sapien roots in Africa and selected timeline events that were concurrent with prehistoric human life in Europe. Prehistoric Homo Sapiens in Europe Genetic, carbon dating and archeological evidence suggest that our own species, Homo sapiens, first appeared between 150 and 200 thousand years ago in Africa and migrated to Europe and Asia. The earliest archeological finds that exhibit all the characteristics of modern humans, including large rounded brain cases and small faces and teeth, date to 190 thousand years ago at Omo, Ethiopia. 1 IBM announced in 2011 that the Genographic Project, charting human genetic data, supports a southern route of human migration from Africa via the Bab-el-Mandeb Strait in Arabia, suggesting a role for Southwest Asia in the “Out of Africa” expansion of modern humans.

Forteviot, Perthshire 2008: Excavations of a Henge Monument and Timber Circle Data Structure and Interim Report
Forteviot, Perthshire 2008: Excavations of a henge monument and timber circle Data Structure and Interim Report by Gordon Noble and Kenneth Brophy Forteviot Henge Excavations 2008 Summary This interim report will describe the provisional outcomes of our excavations, part of the SERF (Strathearn Environs and Royal Forteviot) Project, in a field immediately to the S of Forteviot village, Perth and Kinross, in August 2008. Our focus in the 2008 summer season was two elements of the Forteviot cropmark complex: a possible late Neolithic henge monument, and an adjacent pit-defined setting. Both these features are located within the large Neolithic palisaded enclosure, partially excavated in 2007 (see Brophy & Noble 2008). Trench 2 revealed information both about the henge monument, but also extensive later reuse of the site. Trench 3 was opened over the location of the possible timber-setting; this was not identified in the trench, but a large pit with burnt material and a number of other features were found, not all of which are identifiable as cropmarks. In many ways, this was a much more difficult season of excavation than Trench 1 in 2007, partly due to wetter weather conditions, but also to a large extent because of the complexity of the archaeology, especially in Trench 2, which one would not normally expect of a cropmark site. This report therefore contains results and interpretations that are provisional and a second season of excavation in and around this henge will be required in 2009 which will, we hope, answer some of the many questions raised by the 2008 season.

New Discovery of Rock Art and Megalithic Sites in the Central Plain of China
Rock Art Research 2012 - Volume 29, Number 2, pp. 157-170. TANG H. 157 KEYWORDS: Cupule – Rock art – Megalith – Cross-dating – Central Plain of China NEW DISCOVERY OF ROCK ART AND MEGALITHIC SITES IN THE CENTRAL PLAIN OF CHINA Tang Huisheng Abstract. Since the turn of this century, an immense amount of rock art has been discovered in Henan Province (located in the Central Plains region of China), centred at Mt Juci. Over 90 percent of the rock art consists of cupules and the remainder comprises linear groove patterns, chessboard-like designs and other motifs. The rock art features mainly ground motifs and patterns chiselled by metal tools. There are a variety of cupules, varying in size, depth and arrangement, e.g. occurring in rows, concentric patterns and so on. Rock art was executed on over 10 000 boulders, some of which could be classified as megalithic sites, such as menhirs, dolmen, ‘stone altars’ and the like. The cupules and the megaliths from the Central Plains region appear to show a structural context, which will help us to understand and identify their cultural nature, contents and ages. Based on cross-dating, their production could be considered as spanning the Neolithic and the Bronze Age. Since the turn of this century, a large quantity of a considerable surprise — not only to rock art studies, rock art has been discovered at Mt Juci, in Henan Pro- but also to archaeological studies and studies of early vince (located in the Central Plains region of China), Chinese history. Herein, we introduce the rock art of which has captured public attention and stimulated the Central Plain based on information mainly from Mt extensive interest in rock art studies.
