egyptian sky kingdom god


The ancient Greeks and Romans believed that the Egyptians invented astrology. Astrology is the divination of the supposed influences of the stars and planets on human activity and events on earth by their positions and aspects. Though the Egyptians indeed studied the stars, the belief that the stars influenced events on earth was probably a later development and not a major part of Egyptian philosophy. Yet it is clear that at varying points in Egyptian history, they did believe in power of the stars in terms of protection and future knowledge. It was Greek and Roman interpretations of these beliefs that created the field of modern-day astrology.


In Pyramid Text 1583, dating to the Old Kingdom (2675–2170 B.C.E. ), the king after his death becomes a star in the sky among the gods. Yet this set of spells for a royal funeral stresses the role of the daytime sky and the sun over the stars in the royal afterlife. As Egyptian thought about the afterlife developed, the sun took the most prominent place and was the only celestial body found in the next world. The sun’s journey at night lighted the next world, according to Egyptian belief. Yet the Egyptians surely took some interest in the nighttime sky, especially to calculate the calendar and help measure time. During the First Intermediate Period (2130–2008 B.C.E. ) and the Middle Kingdom (2008–1630 B.C.E. ) some coffins include star charts that the Egyptians used to calculate the dates for celebrating holidays. In the New Kingdom (1539–1075 B.C.E. ), star ceilings were painted in some tombs and temples. Senenmut, a high official in the reign of Hatshepsut (1478–1458 B.C.E. ), had the Egyptian constellations painted on the ceiling of his tomb. The Ramesseum, a temple built by Ramesses II (1279–1213 B.C.E. ) for his continued worship after his death, portrays the god Thoth at the center of the star ceiling. The stars’ role in establishing the calendar led to Thoth’s depiction here. Thoth was the god responsible for both time and for fixing the calendar. There are also scattered references in the New Kingdom to worshipping stars. In the Book of the Dead Chapter 135, an illustration shows the deceased praying before a blue nighttime sky filled with stars. The same scene is included on the walls at the tomb of Senedjem in Deir el-Medina (reign of Ramesses II, 1292–1213 B.C.E. ). A stele in a museum in Hanover, Germany, shows Thoth as the moon god worshipped with two goddesses with stars on their heads. The text speaks of the moon and the stars of the sky. Yet none of these texts mention any influence the stars could have on life on earth. The planets had names formulated with the name of the god Horus. Yet even these names only appear in lists and never seem to play a role in religion.


The decans were 36 stars whose rising marked a night hour equivalent to forty minutes on the modern clock. Every ten days a different star marked the beginning of the night. The principal star was Sirius, already an important marker for the beginning of the New Year. All the decans disappear from the sky for seventy days then first return to view just before sunrise. This is called a star’s helical rising. Each star’s rising pinpointed the start of a new ten-day week on the civil calendar. Three of these weeks formed one month. After the star reappeared, it joined the others that were visible. At any one time there were eighteen visible stars. They were spaced in eighteen one-hour intervals across the sky. This system created a clock consisting of eighteen hours at night equivalent to the modern 12 hours. This system developed during the Middle Kingdom. Because the decans disappeared and reappeared on a regular basis, the Egyptians identified them as symbols of death and regeneration. In the New Kingdom, the king’s funeral temples included lists of the decans. Some officials’ tombs in the Ramesside Period (1292–1075 B.C.E. ) included the decans on the ceiling. In the tomb of Ramesses VI (1145–1137 B.C.E. ) the decans are represented worshipping the regenerating sun. Yet in the Twenty-first Dynasty (1075–945 B.C.E. ) some officials believed it necessary to wear amulets to protect them from dangers caused by the decans. These amulets seem to represent a sudden change in attitude toward the stars.


The Egyptians recognized that a dangerous power could be either a threat or a protector. Though the Twenty-first Dynasty amulets suggest the decans are a threat to people, by the reign of Osorkon II (874–835/30 B.C.E. ) there is evidence that the decans’ power had been harnessed to protect the king. Two arm-bands from Osorkon II’s tomb depict the decans with the gods Osiris, Horus, Thoth, Isis, and Nephthys. The decans are snakes with lion’s heads who now protect the king. This is due to the belief that the goddess Sakhmet had control of the decans in this period. Sakhmet was a lion-headed goddess responsible for sending illness to people but also capable of curing illness. Thus Sakhmet also has a clear connection with fate, as is further supported by the inscriptions on the armbands. The decans also appear on protective amulets and necklaces in this period. By wearing this jewelry, a person could claim their protection.


By the reign of Darius I (524–486 B.C.E. ), the decans appear on the temple of Hibis in the Kharga Oasis. They also appear on a shrine of Nectanebo I (381–362 B.C.E. ) and a chapel of Ptolemy VIII (ruled 170–163 and 145–116 B.C.E. ). Though widely spaced in time, these monuments show that the decans continued to expand their influence. The shrine of Nectanebo I includes inscriptions that claim the decans can affect wind and water, bring fertility to the fields, and cause illness and sudden death. The decans also influenced specific parts of the body, an idea that would later receive much elaboration.


The first millennium B.C.E. Egyptian view that the decans could influence certain phenomena on earth, including specific parts of the human body, was incorporated into heretical early Christian texts found at Nag Hammadi in Upper Egypt. The Apocryphon of John includes ancient Egyptian names along with Greek and Semitic names. It also connects the decans and some constellations with influence over different parts of the body. A Coptic text also from Nag Hammadi describes the decans as many-faced demons associated with both death and the devil. These texts combined a Greek idea of fate and a theory of how an individual’s pre-assigned fate could be avoided. In Greek magical texts, the god Sarapis can help an individual avoid his fate through reciting the proper spell. This fate was assigned by the stars. Yet only one small part of this theory descends from ancient Egyptian sources, the decans and their ability to influence events on earth.


Two known Egyptian astrologers were active in the second century B.C.E. during the reigns of Ptolemy VI and Ptolemy VIII. One was Harchebis who claimed to know the mysteries of the stars and the mysteries of snakes. He also claimed in an inscription on his statue that he had observed the heavens, especially the planet Venus. The priest Petosiris claimed to be the author of an astrological handbook. Petosiris traced his own sources to the Twenty-sixth Dynasty (664–525 B.C.E. ), though it is not clear how reliable this information is. Thus the real origin of Egyptian astrology probably was in this mixed society, depending on both Egyptian and Greek sources for its information.


The zodiac certainly played a role in later Egyptian star study, yet it only became known in Egypt in the Ptolemaic Period (332–30 B.C.E. ). The first zodiac in Egypt was carved in the temple located in Esna built in the reigns of Ptolemy III and Ptolemy IV (246–205 B.C.E. ). The origin of this zodiac was most probably Babylon. It contains Babylonian forms of some signs such as the goat-fish for Capricorn, a two-headed winged horse for Sagittarius, a maiden with ears of wheat, and a crab to represent Cancer. Other signs were Egyptianized such as Aquarius as a Nile god. Some scholars have attempted to identify the whole zodiac with Egyptian symbols. But Erik Hornung suggested that the symbols became more Egyptian the longer they were used in Egypt. The origin appears to be Babylonian.


After the Roman conquest of Egypt (30 B.C.E. ), astrology became even more popular. The emperor Augustus forbade private consultations with astrologers in 11 C.E. , a sign that they had become increasingly common. Yet Augustus issued coins with his own zodiacal sign. The emperor Tiberius (r. 14–37 C.E. ) took a great interest in astrology and executed those whose horoscope indicated they could be emperors. Egyptian astrologers were popular at the emperor Nero’s court (r. 54–68 C.E. ). Nero appointed the astrologer Balbillus a prefect of Egypt from 55 to 59 C.E. All of this activity must have played a role in Egypt’s reputation for expertise in astrology. Yet it was relatively late in Egyptian history and had little to do with classical Pharaonic civilization.
