Vedic India),[7] but apparently the name "bear" has parallels in Siberian or North American traditions.[8][9][10]

European astronomy

The name "Bear" is Homeric, and apparently native to Greece, while the "Wain" tradition is Mesopotamian. Book XVIII of Homer's Iliad mentions it as "the Bear, which men also call the Wain".[11] In Latin, these seven stars were known as the "Seven Oxen" (septentriones, from septem triōnēs).[12] Classical Greek mythography identified the "Bear" as the nymph Callisto, changed into a she-bear by Hera, the jealous wife of Zeus.

In Ireland and the United Kingdom, this pattern is known as the Plough (Irish: An Camchéachta – the bent plough). The

Little Dipper).[15][16] An older "Odin's Wain" may have preceded these Nordic designations.[14]

Woden's wagon".[17] In Dutch, its official name is the "Great Bear" (Grote Beer), but it is popularly known as the "Saucepan" (Steelpannetje). In Italian, it is called either the "Great Wagon" (Grande Carro
) or "Orsa Maggiore" ("Greater Bear").

shaman) in Hungarian mythology who carried medicine that could cure any disease. In Finnish, the figure is known as Otava with established etymology in the archaic meaning 'salmon net', although other uses of the word refer to 'bear' and 'wheel'.[18] The bear relation is claimed to stem from the animal's resemblance to—and mythical origin from—the asterism rather than vice versa.[19][20]

In Lithuanian, the stars of Ursa Major are known as Didieji Grįžulo Ratai ("The Big Back Wheels"). Other names for the constellation include Perkūno Ratai ("The Wheels of Perkūnas"), Kaušas ("The Bucket"), Vežimas ("The Carriage"), and Samtis ("The Ladle").[citation needed]

Asian traditions

In

Alpha Ursae Majoris is Beidou Yi (Chinese: 北斗一; pinyin: Běi Dǒu yī; lit. 'Beidou One') and Tianshu (Chinese: 天樞; pinyin: Tiān Shū; lit. 'Star of Celestial Pivot').[22] The asterism name was mentioned in Warring States period (c. 475–221 BCE) stellar records, in which the asterism is described to have seven stars in the shape of a dipper or a chariot.[23][failed verification
]

The Chinese astronomy records were translated to other

Northern Celestial Pole, although numerous other groupings and names have been made over the centuries. Similarly, each star has a distinct name, which likewise has varied over time and depending upon the asterism being constructed.[26] The personification of the Big Dipper itself is also known as "Doumu" (斗母) in Chinese folk religion and Taoism, and Marici in Buddhism
.

In Vietnam, the colloquial name for the asterism is Sao Bánh lái lớn (The Big Rudder Stars), contrasted with Ursa Minor, which is known as Sao Bánh lái nhỏ (The Little Rudder Stars).[27] Although this name has now been replaced by the Sino-Vietnamese "Bắc Đẩu" in everyday speech, many coastal communities in central and southern Vietnam still refer to the asterism as such and use it to navigate when their fishing vessels return from the sea at night.[28]

In Malay, it is known as the "Boat Constellation" (Buruj Biduk); in Indonesian, as the "Canoe Stars" (Bintang Biduk).[29]

In Burmese, these stars are known as Pucwan Tārā (ပုဇွန် တာရာ, pronounced "bazun taja"). Pucwan (ပုဇွန်) is a general term for a crustacean, such as prawn, shrimp, crab, lobster, etc.[30]

While its Western name come from the star pattern's resemblance to a

Little Dipper are more often associated with the tabo, a one-handled water pot used ubiquitously in Filipino households and bathrooms for purposes of personal hygiene.[citation needed
]

In the earliest

Saptarishi, "Seven Sages."[7]

Inuit traditions

In Inuit astronomy, the same grouping of stars is referred to as "the Caribou" (Tukturjuit). Many of the stars within the constellation "were used as hour hands on the night sky to indicate hours of the night, or as calendar stars to help determine the date in fall, winter, or spring."[31]

In North America

The asterism name "Big Dipper" is mostly used in the

folk songs; however, a more recent source challenges the authenticity of the claim.[33]

In an 1824 book on the history of the constellations' mythology, Jacob Green [fr] contrasted the "Dipper or Ladle" descriptors used in the United States with "Charles's Wagon or Wain" which were common in England.[34] Descriptions of "the dipper" appear in American astronomy textbooks throughout the 19th century.[35][36][37]

Stars

Within Ursa Major the stars of the Big Dipper have Bayer designations in consecutive Greek alphabetical order from the bowl to the handle.

Five of the stars of the Big Dipper are at the core of the

Ursa Major Moving Group. The two at the ends, Dubhe and Alkaid, are not part of the swarm, and are moving in the opposite direction. Relative to the central five, they are moving down and to the right in the map. This will slowly change the Dipper's shape, with the bowl opening up and the handle becoming more bent. In 50,000 years the Dipper will no longer exist as we know it,[citation needed
] but be re-formed into a new Dipper facing the opposite way. The stars Alkaid to Phecda will then constitute the bowl, while Phecda, Merak, and Dubhe will be the handle.

Guidepost

Guide to using Big Dipper to locate Arcturus, Spica, and Polaris

Not only are the stars in the Big Dipper easily found themselves, they may also be used as guides to yet other stars. Thus it is often the starting point for introducing Northern Hemisphere beginners to the night sky:

  • Polaris, the North Star, is found by imagining a line from Merak (β) to Dubhe (α) and then extending it for five times the distance between the two Pointers.
  • Extending a line from Megrez (δ) to Phecda (γ), on the inside of the bowl, leads to RegulusLeonis) and AlphardHydrae). A mnemonic for this is "A hole in the bowl will leak on Leo."
  • Extending a line from Phecda (γ) to Megrez (δ) leads to ThubanDraconis), which was the pole star 4,000 years ago.
  • Crossing the top of the bowl from Megrez (δ) to Dubhe (α) takes one in the direction of CapellaAurigae). A mnemonic for this is "Cap to Capella."
  • CastorGeminorum) is reached by imagining a diagonal line from Megrez (δ) to Merak (β) and then extending it for approximately five times that distance.
  • By following the curve of the handle from Alioth (ε) to Mizar (ζ) to Alkaid (η), one reaches ArcturusBoötis) and SpicaVirginis). A mnemonic for this is "Arc to Arcturus then speed (or spike) to Spica."

Additionally, the Dipper may be used as a guide to telescopic objects:

  • The approximate location of the Hubble Deep Field can be found by following a line from Phecda (γ) to Megrez (δ) and continuing on for the same distance again.
  • Crossing the bowl diagonally from Phecda (γ) to Dubhe (α) and proceeding onward for a similar stretch leads to the bright galaxy pair M81 and M82.
  • Two spectacular spiral galaxies flank Alkaid (η), the
    Whirlpool
    (M51) to the south.
  • Projecting a line from Alkaid (η) through the pole star will point to Cassiopeia.

Cultural associations

The "Seven Stars" referenced in the Bible's Book of Amos[38] may refer to these stars or, more likely, to the Pleiades.

In traditional Hindu astronomy, the seven stars of the Big Dipper are identified with the names of the Saptarshi.

In addition, the asterism has also been used in corporate logos[39] and the Alaska flag. The seven stars on a red background of the Flag of the Community of Madrid, Spain, are the stars of the Big Dipper Asterism. The same can be said about the seven stars pictured in the bordure azure of the Coat of arms of Madrid, capital city of Spain.[40]

The asterism's prominence on the north of the night sky produced the adjective "septentrional" (literally, pertaining to seven plow oxen) in Romance languages and English, meaning "Northern [Hemisphere]".

"

folk song first published in 1928. The "Drinkin' Gourd" is thought to refer to the Big Dipper. Folklore has it that escaped southern slaves in the United States used the Big Dipper as a point of reference to go north.[41][42]

A mythological origin of the asterism was described in a children's story which circulated in the United States in various versions.[43][44] A version of this story taken from the pacifist magazine Herald of Peace was translated into Russian and incorporated into Leo Tolstoy's compilation A Calendar of Wisdom.[45][46]

The Constellation was also used on the flag of the Italian Regency of Carnaro within the Ouroboros.

The conformation of the seven stars in no way resembles the animal, — indeed the contrary; yet they called them Okuari and Paukunawa, words for a "bear", before they were visited by the white men, as is attested by Le Clercq in 1691, by the Reverend Cotton Mather in 1712, by the Jesuit missionary La Fitau in 1724, and by the French traveler Charlevoix in 1744. And Bancroft wrote in his history of our country: [...] In justice, however, to their familiarity with a bear's anatomy, it should be said that the impossible tail of our Ursa was to them either Three Hunters, or a Hunter with his two Dogs, in pursuit of the creature; the star Alcor being the pot in which they would cook her. They thus avoided the incongruousness of the present astronomical ideas of Bruin's make-up, although their cooking-utensil was inadequate. The Housatonic Indians, who roamed over that valley from Pittsfield through Lenox and Stockbridge to Great Barrington, said that this chase of the stellar Bear lasted from the spring till the autumn, when the animal was wounded and its blood plainly seen in the foliage of the forest."
