Decan
The decans (; Egyptian ''bꜣktw'' or ''baktiu'', "[those] connected with work") are 36 groups of stars (small constellations) used in the Egyptian astronomy, ancient Egyptian astronomy to conveniently divide the 360 degree ecliptic into 36 parts of 10 degrees each, both for theurgical and Heliacal rising, heliacal horological purposes. The decans each appeared, geocentrically, to rise consecutively on the horizon throughout each daily Earth rotation. The rising of each ''decan'' marked the beginning of a new decanal "hour" (Greek ''hōra'') of the night for the ancient Egyptians, and they were used as a sidereal star clock beginning by at least the 9th or 10th Dynasty (c. 2100 BCE). Because a new decan also appears heliacal rising, heliacally every ten days (that is, every ten days, a new decanic star group reappears in the eastern sky at dawn right before the Sun rises, after a period of being obscured by the Sun's light), the ancient Greeks called them ''dekanoi'' (δεκανο ...

Decan (astrology)
In astrology, a ''decan'' is the subdivision of a sign. In order to give fuller interpretation to the zodiac signs, ancient astrologers subdivided each sign into periods of approximately ten days. These divisions are known as the "decans" or "decanates" and cover modifications of individual traits, attributed to minor planetary influences, which temper or blend with the ruling influence of the period. The ten-day spans are somewhat arbitrary in order to allow for the five (and sometimes six) extra days in the year beyond the 360 days required for the thirty-six decans. Each sign is allocated a triplicity, consisting of three of the four classical elements air, water, earth or fire, and is therefore subdivided into three equal parts of 10 degrees each; these parts are referred to as ''decans'' or ''decanates''. Each decan of a sign is assigned Domicile (astrology), rulership by the planet ruling the sign and secondary rulership by the planet ruling the decan. In Ptolemy The deca ...

Book Of Nut
The ''Book of Nut'' (original title: ''The Fundamentals of the Course of the Stars'') is a collection of Ancient Egypt, ancient Egyptian astronomical texts focusing on mythological subjects, cycles of the stars of the decans, and the movements of the moon, sun, and planets on sundials. It is titled for the sky goddess Nut (goddess), Nut who is depicted in some copies of the text arching over the earth. She is supported by the god of the air Shu (Egyptian deity), Shu. Texts in the ''Book of Nut'' include material from different periods of Egyptian history. The original name of the book, ''The Fundamentals of the Course of the Stars'', was discovered by Alexandra von Lieven in one of the manuscript fragments and published in 2007. One of the major themes of the ''Book of Nut'' is the concept of sunrise as the mythological rebirth. Texts There are nine different copies of the book and they have various dates. Three copies are found on monuments and six more are found in the papy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hellenistic Astrology
Hellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean Basin region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek (or sometimes Latin). The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era. History The origins of much of the astrology that would later develop in Asia, Europe and the Middle East are found among the ancient Babylonians and their system of celestial omens that began to be compiled around the middle of the 2nd millennium BC, 2nd millennium BCE. This sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hour
An hour (symbol: h; also abbreviated hr) is a unit of time historically reckoned as of a day and defined contemporarily as exactly 3,600 seconds ( SI). There are 60 minutes in an hour, and 24 hours in a day. The hour was initially established in the ancient Near East as a variable measure of of the night or daytime. Such seasonal hours, also known as temporal hours or unequal hours, varied by season and latitude. Equal hours or equinoctial hours were taken as of the day as measured from noon to noon; the minor seasonal variations of this unit were eventually smoothed by making it of the mean solar day. Since this unit was not constant due to long term variations in the Earth's rotation, the hour was finally separated from the Earth's rotation and defined in terms of the atomic or physical second. It is a non-SI unit that is accepted for use with SI. In the modern metric system, one hour is defined as 3,600 atomic seconds. However, on rare occasions an hour may inc ...

Testament Of Solomon
The Testament of Solomon is a pseudepigraphical composite text ascribed to King Solomon but not regarded as canonical scripture by Jews or Christian groups. It was written in the Greek language, based on precedents dating back to the early 1st millennium AD, but was likely not completed in any meaningful textual sense until sometime in the Middle Ages. In its most noteworthy recensions, the text describes how Solomon was enabled to build his temple by commanding demons by means of a magical ring that was entrusted to him by the archangel Michael. Dating and authorship Scholarly opinion on when the Testament of Solomon was written varies widely. Suggested dates for its composition range between the end of the 1st century AD and the High Middle Ages. Also disputed is whether it had a Christian or Jewish origin. Mid-twentieth century scholarship tended to agree that much of its content "reflects the first-century Judaism in Israel" and includes material much earlier than its com ...

Dendera Zodiac
The sculptured Dendera zodiac (or Denderah zodiac) is a widely known Art of ancient Egypt, Egyptian bas-relief from the ceiling of the ''pronaos'' (or portico) of a chapel dedicated to Osiris in the Dendera Temple complex, Hathor temple at Dendera, containing images of Taurus (astrology), Taurus (the Bull (mythology), bull) and Libra (astrology), Libra (the scales). This chapel was begun in the late History of Ptolemaic Egypt, Ptolemaic period; its ''pronaos'' was added by the emperor Tiberius. This led Jean-François Champollion to date the relief to the Hellenistic civilization, Greco-History of Roman Egypt, Roman period, but most of his contemporaries believed it to be of the New Kingdom of Egypt, New Kingdom. The relief, which John H. Rogers characterised as "the only complete map that we have of an ancient sky", has been conjectured in the past to represent the basis on which later astronomy systems were based. It is now on display at the Musée du Louvre, Paris. Descripti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Astronomy
Egyptian astronomy started in prehistory, prehistoric times, in the Prehistoric Egypt, Predynastic Period. In the 5th millennium BCE, the stone circles at Nabta Playa may have made use of astronomical alignments. By the time the historical Ancient Egypt, Dynastic Period began in the 3rd millennium BCE, the 365 day period of the Egyptian calendar was already in use, and the observation of stars was important in determining the annual flooding of the Nile. The Egyptian pyramids were carefully aligned towards the pole star, and the temple of Amun, Amun-Re at Karnak was aligned on the rising of the winter solstice, midwinter Sun. Astronomy played a considerable part in fixing the dates of religious festivals and determining the hours of night, and temple astrology, astrologers were especially adept at watching the stars and observing the conjunction (astronomy), conjunctions and risings of the Sun, Moon, and planets, as well as the lunar phases. In Ptolemaic Kingdom, Ptolemaic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms Asterism (astronomy), a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The first constellations were likely defined in prehistory. People used them to relate stories of their beliefs, experiences, creation myth, creation, and mythology. Different cultures and countries invented their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. Naming constellations also helped astronomers and navigators identify stars more easily. Twelve (or thirteen) ancient constellations belong to the zodiac (straddling the ecliptic, which the Sun, Moon, and planets all traver ...

Lunar Station
Often called lunar mansion, a lunar station or lunar house is a segment of the ecliptic through which the Moon passes in its orbit around the Earth. The concept was used by several ancient cultures as part of their calendrical system. Stations in different cultures In general, though not always, the zodiac is divided into 27 or 28 segments relative to the vernal equinox point or the fixed stars – one for each day of the lunar month. (A sidereal month lasts about days.) The Moon's position is charted with respect to those fixed segments. Since the Moon's position at any given stage will vary according to Earth's position in its own orbit, lunar stations are an effective system for keeping track of the passage of seasons. Various cultures have used sets of lunar stations astrologically; for example, the Jyotisha astrological ''nakshatras'' of Hindu culture, the Arabic manzils (''manāzil al-qamar''), the Twenty-Eight Mansions of Chinese astronomy, and the 36 ...

Heliacal Rising
The heliacal rising ( ) of a star or a planet occurs annually when it becomes visible above the eastern horizon at dawn just before sunrise (thus becoming "the Morning Star (other)#Astronomy, morning star"). A heliacal rising marks the time when a star or planet becomes visible for the first time again in the night sky after having set with the Sun at the western horizon in a previous sunset (its heliacal setting), having since been in the sky only during daytime, obscured by sunlight. Historically, the most important such rising is that of Sirius, which was an important feature of the Egyptian calendar and Egyptian astronomy, astronomical development. The rising of the Pleiades heralded the start of the Ancient Greek sailing season, using celestial navigation, as well as the farming season (attested by Hesiod in his Works and Days). Heliacal rising is one of several types of risings and settings, mostly they are grouped into morning and evening risings and settings of obj ...

Zodiac
The zodiac is a belt-shaped region of the sky that extends approximately 8° north and south celestial latitude of the ecliptic – the apparent path of the Sun across the celestial sphere over the course of the year. Within this zodiac belt appear the Moon and the brightest planets, along their orbital planes. The zodiac is divided along the ecliptic into 12 equal parts, called " signs", each occupying 30° of celestial longitude. These signs roughly correspond to the astronomical constellations with the following modern names: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The signs have been used to determine the time of the year by identifying each sign with the days of the year the Sun is in the respective sign. In Western astrology, and formerly astronomy, the time of each sign is associated with different attributes. The zodiacal system and its angular measurement in 360 sexagesimal degree ...
