In the video, David Bowie is wearing the same things he was wearing when he was interested into Kabbalah and Egyptian stuff. Kabbalah is the ancient Jewish tradition of mystical interpretation of the Bible, first transmitted orally and using esoteric methods (including ciphers). It reached the height of its influence in the later Middle Ages and remains significant in Hasidism. One cover shows him actually as a Pharaoh. Which brings an interesting side note his saxophonist said in the Rolling Stones interview regarding the song Blackstar: "He told me it was about ISIS," says McCaslin. "It's just an unbelievable tune." However, McCaslin's ISIS assertion is news to Guiliana and Visconti, who say they have no idea what the song is about." Bowie was misunderstood here. If Bowie really said this, he was referring to the Egyptian goddess Isis. Because she was seen as "the friend of slaves, sinners, artisans and the downtrodden"...the star Sopdet (Sirius) is associated with Isis. The appearance of the star signified the advent of a new year and Isis was likewise considered the goddess of rebirth and reincarnation, and as a protector of the dead. The Book of the Dead outlines a particular ritual that would protect the dead, enabling travel anywhere in the underworld, and most of the titles Isis holds signify her as the goddess of protection of the dead." "Then here comes the weird part: "But in addition, Isis was also represented as the mother of the "four sons of Horus", the four deities who protected the canopic jars containing the pharaoh's internal organs. More specifically, Isis was viewed as the protector of Imsety." Imsety is not associated with any animal and is always depicted as human. He is a funerary deity, one of the Four sons of Horus, who are associated with the canopic jars, specifically the one that contained the liver. Isis' brother and husband was Osiris who was the God of the underworld which might corrolate back to Lazarus and ressurection. Their son was Horus, God of the rising/setting sun. It's believed that Horus injured one of his eyes (like Bowie did at 15) and after it healed it became a symbol of perfection/soundness which lead to the Eye of Horus symbol. In Crowleyism (and maybe the Kaballah..I don't know enough about it) they also believe the Aeon of Horus to be an era of free will on earth.
Isis is one of the most important goddesses of ancient Egypt. Her name is the Greek form of an ancient Egyptian word for "throne." Isis was initially an obscure goddess who lacked her own dedicated temples, but she grew in importance as the dynastic age progressed, until she became one of the most important deities of ancient Egypt. Her cult subsequently spread throughout the Roman Empire, and Isis was worshipped from England to Afghanistan. She is still revered by pagans today. As mourner, she was a principal deity in rites connected with the dead; as magical healer, she cured the sick and brought the deceased to life; and as mother, she was a role model for all women. Isis had strong links with Egyptian kingship, and she was most often represented as a beautiful woman wearing a sheath dress and either the hieroglyphic sign of the throne or a solar disk and cow's horns on her head. Occasionally she was represented as a scorpion, a bird, a sow, or a cow. There are no references to Isis before the 5th dynasty (2465-2325 bce), but she is mentioned many times in the Pyramid Texts (c. 2350-c. 2100 bce), in which she offers assistance to the dead king. Later, as ideas of the afterlife became more democratic, Isis was able to extend her help to all dead Egyptians. The priests of Heliopolis, followers of the sun god Re, developed the myth of Isis. This told that Isis was the daughter of the earth god Geb and the sky goddess Nut and the sister of the deities Osiris, Seth, and Nephthys. Married to Osiris, king of Egypt, Isis was a good queen who supported her husband and taught the women of Egypt how to weave, bake, and brew beer. But Seth was jealous, and he hatched a plot to kill his brother. Seth trapped Osiris in a decorated wooden chest, which he coated in lead and threw into the Nile. The chest had become Osiris's coffin. With his brother vanished, Seth became king of Egypt. But Isis could not forget her husband, and she searched everywhere for him until she eventually discovered Osiris, still trapped in his chest, in Byblos. She brought his body back to Egypt, where Seth discovered the chest and, furious, hacked his brother into pieces, which he scattered far and wide. Transforming into a bird, and helped by her sister, Nephthys, Isis was able to discover and reunite the parts of her dead husband's body-only his penis was missing. Using her magical powers, she was able to make Osiris whole; bandaged, neither living nor dead, Osiris had become a mummy. Nine months later Isis bore him a son, Horus. Osiris was then forced to retreat to the underworld, where he became king of the dead. Isis hid with Horus in the marshes of the Nile delta until her son was fully grown and could avenge his father and claim his throne. She defended the child against attacks from snakes and scorpions. But because Isis was also Seth's sister, she wavered during the eventual battle between Horus and Seth. In one episode Isis took pity on Seth and was in consequence beheaded by Horus (the beheading was reversed by magic). Eventually she and Horus were reconciled, and Horus was able to take the throne of Egypt. Isis was the perfect traditional Egyptian wife and mother-content to stay in the background while things went well, but able to use her wits to guard her husband and son should the need arise. The shelter she afforded her child gave her the character of a goddess of protection. But her chief aspect was that of a great magician, whose power transcended that of all other deities. Several narratives tell of her magical prowess, far stronger than the powers of Osiris and Re. She was frequently invoked on behalf of the sick, and, with the goddesses Nephthys, Neith, and Selket, she protected the dead. Isis became associated with various other goddesses, including Bastet, Nut, and Hathor, and thus her nature and her powers became increasingly diverse. Isis became known, like other fierce goddesses in the Egyptian pantheon, as the "Eye of Re" and was equated with the Dog Star, Sothis (Sirius). The first major temple dedicated to Isis was built by the Late Period kingNectanebo II (360-343 bce) at Behbeit el-Hagar, in the central Nile delta. Other important temples, including the island temple of Philae, were built during Greco-Roman times when Isis was dominant among Egyptian goddesses. Several temples were dedicated to her in Alexandria, where she became the patroness of seafarers. From Alexandria her cult spread to Greece and Rome. Images of Isis nursing the baby Horus may have influenced the early Christian artists who depicted the Virgin Mary with the baby Jesus. In the typical form of her myth, Isis was the first daughter of Geb, god of the Earth, and Nut, goddess of the Sky, and she was born on the fourth intercalary day. She married her brother, Osiris, and she conceived Horus by him. Isis was instrumental in the resurrection of Osiris when he was murdered by Set. Using her magical skills, she restored his body to life after having gathered the body parts that had been strewn about the earth by Set. Most Egyptian deities were first worshipped by local cults, eventually their popularity spread - so that most major cities and towns in Egypt were known as the home of a particular deity. The origins of the cult of Isis are uncertain, but it is believed that she was originally an independent and popular deity in predynastic times, prior to 3100 BCE, at Sebennytos in the Nile delta. The first written references to Isis date back to the Fifth dynasty of Egypt. Based on the association of her name with the throne, some early Egyptologists believed that Isis's original function was that of throne-mother. However, more recent scholarship suggests that aspects of that role came later by association. In many African tribes, the throne is known as the mother of the king, and that concept fits well with either theory, possibly giving insight into the thinking of ancient Egyptians. The Isis-Osiris Myth myth became very important during the Greco-Roman period with sanctuaries at Delos and Pompeii. It was believed that the Nile River flooded every year because of the tears of sorrow which Isis wept for Osiris. Osiris's death and rebirth was relived each year through rituals. The worship of Isis eventually spread throughout the Greco-Roman world, continuing until the suppression of paganism in the Christian era.
