The regularities of constructing crucial architectural forms are shown based on the architecture of Ancient Egypt, Western Europe, and Russia: obelisks, pyramids, statues, tents, and spires. It is shown that the source of projection for these and some other architectural forms was the Sun 1 or its image in the shape of a golden ball. The sun ray is serving as a tool for solar elevation.

This study is a description and discussion of all known examples of mortar-and-rubble towers in Attica, extending P. Lock's survey of central Greece inBSA81 (1986). Attic towers of this type are generally free-standing and located in places of agricultural rather than strategic importance. In this, as well as in the lack of pretension in their architectural form, they conform to the mortared towers of Boiotia studied by Lock, and reinforce his conclusion that they functioned primarily as fortified residences of Frankish lords. Ceramic evidence from various sites, and the evidence of the ‘tower house’ of medieval western Europe, strengthen the arguments for date and function. Included in the discussion are possible Turkish towers and other pre-modern structures such as windmills and monastery towers.

This chapter examines the influence of the town of Heliopolis—the center of the sun cult in Egypt—on the foundation and development of the royal cemetery in Abusir. It begins with an overview of the history and meaning of the sun cult in ancient Egypt, showing that sun worship in the Nile Valley can be traced to prehistory. It then describes some pyramid complexes built in ancient Heliopolis, including the pyramid complex of Sahure, and the decline of the Abusir necropolis. It also discusses the decline of the Fourth Dynasty and the rise of the Fifth Dynasty; the mystery surrounding three royal mothers, all named Khentkaus; the papyri as fragmentary records of the Abusir pyramid temple administration and economy; Ptashshepses, the vizier and son-in-law of Nyuserre; and the funerary cult of the kings buried at Abusir. The chapter concludes with an assessment of sun temples of the Fifth Dynasty kings.

The five visible planets are certainly attested to in Egyptian sources from about 2000 bce. The three outer ones are religiously connected with the falcon-headed god Horus, Venus with his father Osiris, and Mercury with Seth, the brother and murderer of Osiris. Clear attestations of the planets are largely limited to decoration programs covering the whole night sky. There are a number of passages in religious texts where planets may be mentioned, but many of them are uncertain because the names given to the planets are for most of them not specific enough to exclude other interpretations. There may have been a few treatises giving a more detailed religious interpretation of the planets and their behavior, but they are badly preserved and hardly understandable in the details. In the Late Period, probably under Mesopotamian influence, the sequence of the planets as well as their religious associations could change; at least one source links Saturn with the Sun god, Mars with Miysis, Mercury with Thot, Venus with Horus, son of Isis, and Jupiter with Amun, arranging the planets with those considered negative in astrology first, separated from the positive ones by the vacillating Mercury. Late monuments depicting the zodiac place the planets in positions which are considered important in astrology, especially the houses or the place of maximum power (hypsoma; i.e., “exaltation”). Probably under Babylonian influence, in the Greco-Roman Period mathematical models for calculating the positions and phases of the planets arose. These were used for calculating horoscopes, of which a number in demotic Egyptian are attested. There are also astrological treatises (most still unpublished) in the Egyptian language which indicate the relevance of planets for forecasts, especially for the fate of individuals born under a certain constellation, but also for events important for the king and the country in general; they could be relevant also for enterprises begun at a certain date. There is some reception of supposedly or actually specific Egyptian planet sequences, names and religious associations in Greek sources.

Based on where a painter places her easel, the same landscape will be represented differently. Some objects will appear distant and blurred, others close up and colourful. The sun will light up the sky in a particular and unique way at any given time, so that the very same object may seem different on another day or from another perspective. For an impressionist painter, reality would be represented as a series of broken brush strokes, whereas a Renaissance Florentine painter would emphasize lines and devote time to the geometric construction of the painting. This can be applied as a metaphor for change and stability: according to a researcher’s chosen perspective, she may place greater emphasis on elements that vary, or on those that remain the same, she may pay greater attention to particular details, or focus more on general impressions, so that what she sees as reality is, in fact, only a particular perspective. To understand how conceptions of reality become crystallized within particular research perspectives, it is useful to draw a parallel between party system change and institutional change before presenting the topic of this book: institutional engineering in Western Europe during the last two decades....

Solar blue-violet wavelengths (380−455 nm) are at the high energy end of the visible spectrum; referred to as “high energy visible” (HEV). Both chronic and acute exposure to these wavelengths has been often highlighted as a cause for concern with respect to ocular health. The sun is the source of HEV which reaches the Earth’s surface either directly or after scattering by the atmosphere and clouds. This research has investigated the effect of clouds on HEV for low solar elevation (solar zenith angles between 60° and 80°), simulating time periods when the opportunity for ocular exposure in global populations with office jobs is high during the early morning and late afternoon. The enhancement of “bluing” of the sky due to the influence of clouds was found to increase significantly with the amount of cloud. A method is presented for calculating HEV irradiance at sub-tropical latitudes from the more commonly measured global solar radiation (300–3000 nm) for all cases when clouds do and do not obscure the sun. The method; when applied to global solar radiation data correlates well with measured HEV within the solar zenith angle range 60° and 80° (R2 = 0.82; mean bias error (MBE) = −1.62%, mean absolute bias error (MABE) = 10.3% and root mean square error (RMSE) = 14.6%). The technique can be used to develop repeatable HEV hazard evaluations for human ocular health applications

The popular yet demonic guardian of ancient Egypt, Bes, combines dwarfish and leonine features, and embodies opposing traits such as a fierce and gentle demeanor, a hideous and comical appearance, serious and humorous roles, an animalistic and numinous nature. Drawing connections with similarly stunted figures, great and small cats, sacred cows, baboons, demonic monsters, universal gods and infant deities, this article will focus on the animalistic associations of the Bes figure to illustrate that this leonine dwarf encompassed a wider religious significance than apotropaic and regenerative functions alone. Bes was thought to come from afar but was always close; the leonine dwarf guarded the sun god Ra along the diurnal solar circuit; the figure protected pregnant women and newborn children; it was a dancer and musician; the figure belonged to the company of magical monsters of hybrid appearance as averter of evil and sword-wielding fighter. Exploring the human and animal, demonic and numinous aspects of this leonine dwarf will not only further our understanding of its nature and function, but also its significance and popularity.

The Egyptian concept of medicine was complex and related to a widespread religious belief that combined the worship of gods and the medical arts. The healing properties of food, and especially mother’s milk, were well‑known and endowed with divine qualities. Half‑female‑half‑cow Hathor was usually depicted with cow horns and the sun between them. Since medicine and magic were tightly linked, the omens, facts, conscious and unconscious assumptions merged with a mystical mosaic that formed a volatile but honorable system that is currently regarded as a medical art. Supernatural powers were taken into account, and the meaning of art was associated with the powers attributed to the deities. Despite their obvious social and religious‑political experience, the Egyptians had limited knowledge of the internal structure of human body, paying considerable attention to magic, mysticism and afterlife. They deeply believed that most of the diseases originated in the intestines due to their «contaminated» contents. The main problem in understanding diseases and developing their treatment in ancient Egypt was the restrictions associated with the prohibition of body’s desecration. This was based on the assumption that if the shape of the body is not preserved at the time of resurrection, the soul can be lost in void. Thus, the ancient Egyptians were especially concerned with the preservation of body, believing that desecration by animals or worms could also lead to the complete loss of remains for the soul. In the society of Ancient Rome, illuminated only by the flame of fire and the thirst for knowledge, the enjoyment of food and the continuation of the family were of great importance. Unsurprisingly, the ancients respected the sensations of eating. Thus, such exquisite dishes as lark tongue, black caviar, ostrich brain, Falernian wines at the time of Emperor Heliogabalus evoked a unique complex of sensations during eating. Examples of ancient Roman medical tools, including mirrors, found in the house of a surgeon from Pompeii (72 — 62 BC), prove the early tendency to visualize human insides. The qualification of the ancient masters of medical tools is confirmed by the fact that the principles used two thousand years ago have changed slightly. Thus, there were initial concepts of nutrition, digestion, diseases of the digestive tract, and even the rudiments of diagnosing these diseases in Ancient Egypt and Ancient Rome. They served as the basis for the further development of gastroenterological science.

Four-part figures equal cyclic completion in ancient Mesoamerica, but they do not necessarily correspond to the cardinal directions; they refer, rather, to four-place cycles within the apparent annual path of the sun. The earliest excavated Maya example of such a quadripartite diagram in architectural form is Structure E-VII Sub at Uaxactun, which was part of a solar observatory. Later this E Group at Uaxactun was used for katun celebration. It is suggested that in Early Classic times Mexicans introduced to central Peten a type of celebration of solar cycles observed at Teotihuacan. This new ritual was rapidly Mayanized and institutionalized as the celebration of katuns or 20-year periods. The iconography of katun celebration emphasizes quadripartition and the rainy, stormy sky symbolism of the agricultural year as expressed in Tlaloc ritual at Teotihuacan. Katun celebration probably also served to undermine the original dynastic significance of the ancient Maya Long Count and thus enhanced the public ritual role of the new Mexican elite.
