The Bears Up There Unit of Study: Subjects: Grade Level: Descriptor: Objectives:
Background Our modern constellation system comes from the ancient Greeks. The oldest description of the constellations is found in a poem, Phaenomena, written about 270 BC by the Greek poet Aratus. However, in his poem, Aratus indicates that the constellations originated long before his time. In 150 AD, the Greek scientist Ptolemy published The Almagest, a book that arranges 1022 stars into 48 constellations. These constellations form the basis of our modern constellations system. Today, astronomers recognize 88 constellations. Represented in these constellations are fourteen men and women, nine birds, two insects, nineteen land animals, ten water creatures, two centaurs, one head of hair, one serpent, one dragon, one flying horse, one river, and 29 inanimate objects. Interestingly, most star patterns bear little likeness to the figures they represent. It appears that the "constellation-designators of old" sought to use stellar patterns, not as literal descriptions, but as a way to preserve their own culture in myths and legends. Among the best-known constellations are Ursa Major and Ursa Minor. The Big Dipper, the most recognizable star pattern, is not actually a constellation itself, but is part of Ursa Major--Great Bear to the Greeks. These seven stars of the Big Dipper have inspired many stories. The British call the "dipper" a plow. In Southern France, it is called a saucepan. The Skidi Pawnee Indians saw a stretcher on which a sick man was carried. To the ancient Maya, it was a mythological parrot. Hindu sky lore called it the Wise Men. To the early Egyptians, it was the thigh and leg of a bull. The Chinese saw it as a special chariot for the Emperor of Heaven. For several North American Indian tribes, the bowl of the Big Dipper was a bear, and the stars in the handle represented hunters tracking the bear. And in the 19th Century, the Big Dipper became a symbol of freedom for runaway slaves, who "followed the Drinking Gourd" to the northern states. So there you have it; just about any shape you want to imagine can be assigned to the stars. And for every shape there are countless stories. What bear constellation and story will you create?

Student Handout: Ancient Legend of Ursa Major and Ursa Minor Adapted from the work of Roman Poet Ovid--See Metamorphoses, Book II One day Zeus, the King of the Gods, saw Callisto, a young and beautiful nymph. He fell in love with her. But Callisto was a virgin follower of the virgin goddess Diana. Zeus, taking the form of Diana, approached her, and they conceived a child. Diana, while bathing with her nymphs, realized what had happened. She sent Callisto away. With the birth of Callisto's son (Arcas), Zeus's wife (Hera), understood that her husband had been unfaithful. In her anger and jealous rage, Hera turned Callisto into a bear--a magnificent bear at that! Though a bear in form, Callisto had the heart of a human and the love of a mother. She lived a horrid existence, constantly running from the many hunters who sought to capture her. Years later Callisto, still a bear, crossed paths with Arcas. When she raised up on her hind legs to embrace her son, he drew back his arrow, for he did not recognize the bear as his mother. Zeus, taking pity on the two, changed Arcas into a bear and hurled both mother and son into the sky by their tails. For this reason, both have long tails. Arcas, frozen in the sky, still holds his bow in his little paws. Hera was filled with anger when she saw Callisto glittering with the stars. She went to the ocean to seek help from Oceanos and Thethys--the controllers of the sea. She asked that the Great Bear never be allowed to reach the water and rest as the other inhabitants of the sky. Indeed, in the Northern Hemisphere, the constellation of the Great Bear never touches the ocean. Student Hand-Out: The Great Bear (3 versions of an Iroquois myth) Version A A very long time ago, when the earth was young, a giant bear was chased day after day by a giant Indian chief. One day the Chief caught the bear by his little tail. As the bear roared, the chief swung the bear around his head. Faster and faster, he swung the bear until his tail was stretched long. Then the chief hurled the bear up into the sky where it got stuck. And the bear has been going around every since. Even today the Great Bear spins in a big circle around the northern sky. High overhead, then down towards the horizon, the two bright stars of his body continuously point towards the North Star. Version B While most say there are four main stars in the body of Great Bear and three stars in his tail, we say these three stars are not the tail, but three Indians hunting Great Bear. The three Indians work as a team with a single aim--bear for dinner! The first Indian carries a bow and arrow to shot Great Bear. The last Indian carries a load of firewood to build a fire. And the middle Indian carries a pot on his shoulder to cook the bear in. A faint star next to the middle Indian is the pot. Our story begins when time began, back when the first Indian shot his arrow, struck Great Bear in his side, and began the chase. Because the wound was not serious, day after day Great Bear runs from the pursing Indians. The Indians have never gained a step nor gotten close enough for a second shot. As the Indians chase Great Bear around the night sky, the whole sky seems to turn. As the weeks pass, Great Bear begins each night at a slightly different place in the sky. It is in the autumn season every year, with Great Bear crouched low in the northwest, that unusual things happen. The arrow wound opens slightly, allowing a little blood to trickle down upon the land. The blood stains the leaves of the trees, turning them red. We tell this story so that we won't forget. It is Great Bear that reminds us when it is time to store up food for the cold winter. Version C A very long time ago, Great Bear wandered freely throughout the night sky. He fished and hunted in heavenly rivers and lands. He filled his belly and was happy. What he did not know was that three young braves had seen him feeding. Because winter was coming, they desired Great Bear's skin for clothing and shelter and his meat to feed upon. Suddenly, as though from nowhere, the braves ran out after Great Bear. All summer long, Great Bear ran from the hunters. Eventually, when the first autumn came, the braves' arrows pierced Great Bear. His blood spilled out of the sky and colored the leaves with red and orange. The trees dropped all their leaves in mourning for their friend, Great Bear. The following spring, Great Bear was reborn, as is always the case with bears. And the Indians braves pick up their chase. Every year they do this. Today, if you look into the night sky, you will see the three braves trailing behind Great Bear. |
