Original Form

Meaning
The Serpent, the Dragon
Alpha Draconis. From the Arabic Al Thu'bān, the Serpent or Dragon, the name for the entire constellation applied to the alpha star. Thuban was the pole star during the age of the Egyptian Old Kingdom (c. 2700 BCE), when the Great Pyramid of Giza was constructed. The pyramid's narrow descending passage, angled at 26 degrees, pointed directly at Thuban's lower culmination, and was likely designed so the pole star could be observed from the passage floor both day and night. At that epoch Thuban stood less than two arcminutes from the true pole, closer than Polaris is today. Its slow displacement from the pole over centuries (due to the 26,000 year precession cycle) meant that by the time of the New Kingdom, the star Kochab in Ursa Minor had taken its place. Thuban now sits far from the pole at third magnitude, an inconspicuous star carrying the memory of a former cosmic centrality.
Known As
Thuban in Astrology
Thuban, the former pole star in Draco, carries Saturn-Mars energy that bestows a connection to ancient authority, primal guardianship, and the slow cycles of cosmic power. It grants you a sense of being linked to older, deeper currents of authority than the contemporary world recognizes. Patience measured in epochs characterizes this influence.
Mythology & History
Thuban derives from the Arabic al-Thu'ban, meaning 'the serpent' or 'the dragon,' fitting its position in Draco. Thuban's greatest claim to fame is that it served as the pole star during the third millennium BCE, when the ancient Egyptians were building the Great Pyramids. The descending passage of the Great Pyramid of Giza is precisely aligned to where Thuban would have been visible at its lower culmination. This ancient polar status gives Thuban a deep association with former authority, the turning of ages, and the impermanence of even the most fixed-seeming positions.
Thuban was the north pole star from approximately 3942 BC to 1793 BC, reaching its closest alignment with the celestial pole around 2787 BC, precisely the era when the Great Pyramid of Khufu was built. The descending passage of the Great Pyramid is aligned with where Thuban transited, and the star shaft hypothesis suggests the northern shaft of the King's Chamber pointed toward it. In January 2020, NASA's TESS satellite revealed that Thuban is an eclipsing binary system, a complete surprise despite centuries of study, because the eclipses cause only a 0.1-magnitude brightness dip too subtle for ground-based detection.
Draco Context
Thuban sits in the coils of Draco the Dragon, a constellation that winds around the north celestial pole between Ursa Major and Ursa Minor. Draco has been identified with various dragons and serpents across cultures: the dragon Ladon that guarded the golden apples of the Hesperides, slain by Heracles, or the dragon killed by Cadmus before he founded Thebes. Thuban's position as a former pole star gives it a quality of displaced sovereignty: it once occupied the most important position in the sky but has since yielded that honor to Polaris through the slow grinding of precession.
