Google Earth Pro (GEP) is a powerful tool that can be used for archaeoastronomic and landscape archaeology assessments. Of potential concern, however, is the accuracy of the GEP ruler tool and, in ...particular, the accuracy of heading information. In the present paper the accuracy of GEP heading information is evaluated. Comparative assessments are made using GEP imagery, airport runway diagrams and ground survey data derived from total station solar observations. These analyses indicate that the accuracy of GEP heading data is largely dependent on spatial resolution of the GEP image and length of the line being measured.

This paper presents an astronomical study of a sample of ancient cairns, stelae and burials at the cairnfield of Xiis (Heis) in Somaliland, a historic centre of long-distance trade between different ...cultures. The analyses reveal a set of significant orientations that the paper relates to the seasonal movements of the region’s nomads, which are believed to have remained unchanged for millennia. The structures, which date from the first to the third century AD, are also contextualised within the broader astronomical traditions of the Somali and other Cushitic peoples, many aspects of which predate the arrival of Islam to the Horn of Africa and constitute some of the most distinctive and complex aspects of Somali culture.
This book examines the interplay between astronomy and dynastic power in the course of ancient Egyptian history, focusing on the fundamental role of astronomy in the creation of the pyramids and the ...monumental temple and burial complexes. Bringing to bear the analytical tools of archaeoastronomy, a set of techniques and methods that enable modern scholars to better understand the thought, religion and science of early civilizations, Giulio Magli provides in-depth analyses of the pyramid complexes at Giza, Abusir, Saqqara and Dahshur, as well as of the Early Dynastic necropolis at Abydos and the magnificent new Kingdom Theban temples. Using a variety of data retrieved from study of the sky and measurements of the buildings, he reconstructs the visual, symbolic and spiritual world of the ancient Egyptians and thereby establishes an intimate relationship among celestial cycles, topography and architecture. He also shows how they were deployed in the ideology of the pharaoh's power in the course of Egyptian history.

Maya astronomical tables are recognized in bark-paper books from the Late Postclassic period (1300 to 1521 C.E.), but Classic period (200 to 900 C.E.) precursors have not been found. In 2011, a small ...painted room was excavated at the extensive ancient Maya ruins of Xultun, Guatemala, dating to the early 9th century C.E. The walls and ceiling of the room are painted with several human figures. Two walls also display a large number of delicate black, red, and incised hieroglyphs. Many of these hieroglyphs are calendrical in nature and relate astronomical computations, including at least two tables concerning the movement of the Moon, and perhaps Mars and Venus. These apparently represent early astronomical tables and may shed light on the later books.

At the great city of Tikal, the ancient Maya placed and oriented their ceremonial architecture and monuments in accordance with cosmological principles. Its earliest ceremonial plaza, the Mundo ...Perdido, is one of the oldest pre‐Classic E‐Groups of the Petén, the astronomical utility of which has been a topic of debate by archeologists and archaeoastronomers alike over the past century. In 1988, Aveni and Hartung surveyed the great temples of Tikal and revealed the relationship between their astronomical and dynastic aspects. Yet, over the intervening decades breakthroughs in the decipherment of the Maya glyphs have greatly increased our understanding of Tikal's dynastic history while interpretations in the field of archaeoastronomy have become more rigorous. For instance, more recent surveys and interpretations by Ŝprajc (2021a, 2021b) have demonstrated the importance of the Maya ritual calendar in the placement and orientation of ceremonial public architecture. The aim of this paper is to reassess this earlier fieldwork in archaeoastronomy, provide recent corroborative measurements of the orientation of key buildings, and provide a cohesive summation of the cosmological principles found in the design and construction of the city of Tikal.

The Toba supereruption in Sumatra, ∼74 thousand years (ka) ago, was the largest terrestrial volcanic event of the Quaternary. Ash and sulfate aerosols were deposited in both hemispheres, forming a ...time-marker horizon that can be used to synchronize late Quaternary records globally. A precise numerical age for this event has proved elusive, with dating uncertainties larger than the millennial-scale climate cycles that characterized this period. We report an astronomically calibrated ⁴⁰Ar/ ³⁹Ar age of 73.88 ± 0.32 ka (1σ, full external errors) for sanidine crystals extracted from Toba deposits in the Lenggong Valley, Malaysia, 350 km from the eruption source and 6 km from an archaeological site with stone artifacts buried by ash. If these artifacts were made by Homo sapiens , as has been suggested, then our age indicates that modern humans had reached Southeast Asia by ∼74 ka ago. Our ⁴⁰Ar/ ³⁹Ar age is an order-of-magnitude more precise than previous estimates, resolving the timing of the eruption to the middle of the cold interval between Dansgaard–Oeschger events 20 and 19, when a peak in sulfate concentration occurred as registered by Greenland ice cores. This peak is followed by a ∼10 °C drop in the Greenland surface temperature over ∼150 y, revealing the possible climatic impact of the eruption. Our ⁴⁰Ar/ ³⁹Ar age also provides a high-precision calibration point for other ice, marine, and terrestrial archives containing Toba sulfates and ash, facilitating their global synchronization at unprecedented resolution for a critical period in Earth and human history beyond the range of ¹⁴C dating.
Archaeoastronomy and archaeology are two distinct fields of study which examine the cultural aspect of societies, but from different perspectives. Archaeoastronomy seeks to discover how the impact of ...the skyscape is materialized in culture, by alignments to celestial events or sky-based symbolism; yet by contrast, archaeology's approach examines all aspects of culture, but rarely considers the sky. Despite this omission, archaeology is the dominant discipline while archaeoastronomy is relegated to the sidelines. The reasons for archaeoastronomy’s marginalized status may be found by assessing its history. For such an exploration to be useful, archaeoastronomy cannot just be investigated in a vacuum but must be contextualized by exploring other contemporaneous developments, particularly in archaeology. On the periphery of both, there are various strands of esoteric thought and pseudoscientific theories which paint an alternative view of monumental remains and these also play a part in the background.The discipline of archaeology has had an unbroken lineage from the late 19th century to the present. On the other hand, archaeoastronomy has not been consistently titled, having adopted various different names such as alignment studies, orientation theory, astro-archaeology, megalithic science, archaeotopography, archaeoastronomy and cultural astronomy: names which depict variants of its methods and theory, sometimes in tandem with those of archaeology and sometimes in opposition. Similarly, its academic status has always been unclear so to bring it closer to archaeology there was a proposal in 2015 to integrate archaeoastronomy research with that of archaeology and call it skyscape archaeology. This volume will examine how all these different variants came about and consider archaeoastronomy's often troubled relationship with archaeology and its appropriation by esotericism to shed light on its position today.
The Jesuit missions in South America were an important factor in the evangelisation of the continent during the seventeenth and eighteenth centuries. However, although the history and cultural ...aspects of the distinctive settlements that the missionaries created for indigenous peoples have been examined extensively, studies that address issues relating to archaeoastronomy have only recently begun to appear, primarily in relation to the orientation of churches built for Guaraní peoples in the Jesuit Province of Paraquaria (Province of Paraguay). The current paper continues and complements these studies of the region with the first archaeoastronomical study of the nearby Jesuit missions of Chiquitos in eastern Bolivia, focusing on measurements taken at the ten mission churches, interpreted within the context of the surrounding landscape and the characteristics of the villages where the churches are located. Our results show that in contrast to the churches of the Province of Paraquaria, where north–south meridian orientations predominate, half of the studied Chiquitan Jesuit churches show potential canonical orientations that seem to be aligned to solar phenomena, with three exhibiting precise equinoctial orientation. In this paper I propose reasons for these orientations, including the possible relevance of illumination effects on significant internal elements within the churches – effects that were generally sought in Baroque church architecture.
