Great Bear

greek: Ἄρκτος Μεγάλη (Arktos Megalē) · latin: Ursa Major · egyptian: Meskhetyu (mskhtyw, 'Foreleg of an Ox')

Definition

The Great Bear (Latin Ursa Major; Greek Arktos Megalē) is the northern circumpolar constellation containing the seven-star asterism known as the Big Dipper or Plough. In ancient Egypt this same star group was named Meskhetyu (mskhtyw) — the 'Foreleg of an Ox' — depicted in Middle Kingdom coffin diagrams as a bull's foreleg with four stars marking the bowl and three the handle, and on the Senmut tomb ceiling as a hybrid bull with a three-star tail ending in Zeta Ursae Majoris.

In Tradition

Across Egyptian and Greco-Roman astronomical traditions the Great Bear is read as a circumpolar anchor — never setting from northern latitudes, and therefore reliable as a meridian-determination tool for orientation and timekeeping. The Egyptian Meskhetyu constellation served as the cord-stretching reference for temple foundation rituals from at least the First Dynasty (Palermo Stone evidence). Clagett documents its continuity through the New Kingdom astronomical ceilings of Senmut and Seti I, with progressive iconographic transformations from pure foreleg through hybrid bull-and-foreleg to fully striding bull.

In Practice

Practitioners working with fixed stars treat the bright stars of Ursa Major — particularly Dubhe (Alpha UMa), Merak, Phecda, and Alkaid — as parans (rising/setting/culminating coincidences) with chart points rather than as zodiacal contacts, since the constellation lies far north of the ecliptic. The 'Pointer Stars' (Dubhe and Merak), used to find Polaris, carry directional and orienting symbolism in mundane and electional work. The Egyptian Meskhetyu identification is preserved as part of the broader Egyptian-Hellenistic astronomical inheritance, occasionally invoked in temple-foundation electional symbolism.

Historical Origin

The Egyptian Meskhetyu identification is attested in Middle Kingdom coffin diagrams (ca. 2000-1700 BCE) and continues through the New Kingdom (Senmut tomb ceiling ca. 1473 BCE; Seti I ceiling ca. 1290 BCE). The Greek bear identification (Arktos) is attested in Homer and Hesiod (8th c. BCE) and codified in Aratus's Phaenomena (3rd c. BCE) and Ptolemy's Almagest VII-VIII star catalog. Clagett's Ancient Egyptian Science Vol II documents the iconographic chain from foreleg to bull in detail.

Etymology
