Andromeda Sky Map

Andromeda was the daughter of Cassiopeia the beautiful Aethiopian queen of the city of Joppa in Phoenicia. Cepheus, the king, was her father. Andromeda’s mother, Cassiopeia, was boastful about her natural beauty and especially the beauty of her daughter Andromeda. One day after boasting that she and Andromeda were more beautiful than the sea nymphs, Poseidon, god of the sea, decided to punish the queen for her vanity. He sent a terrible sea monster, Cetus, to destroy Phoenicia. King Cepheus quickly consulted the Oracle at Ammon, where he was advised that Poseidon could only be appeased if the sacrificed their daughter Andromeda to Cetus. So, they chained Andromeda to a rock on a tiny island offshore to await her death. The hero Perseus, returning from killing the Gorgon Medusa saw Andromeda’s plight, slew Cetus and rescued Andromeda. The constellations of Cassiopeia, Cepheus, Andromeda, Perseus, Pegasus and Cetus, represent characters that appear in the story of Perseus.

Antlia Sky Map

This constellation of the southern hemisphere was named in modern times; it contains no bright stars and none with a proper name. Although visible from the mid-northern hemisphere near the horizon due south of Leo when that constellation culminates, Antlia’s stars are so faint that stargazers in antiquity didn’t bother to name them. From 1750 to 1754, French astronomer Nicolas-Louis de Lacaille (1713-1762) compiled a catalog of more than 10,000 stars visible from the Cape of Good Hope; to facilitate his task he mapped out some new constellations. Among these was Antlia Pneumatica, the Air Pump, which he named in honor of the 17th century British chemist Robert Boyle, who invented the compressed-air pump. In 1930 when the International Astronomical Union codified the constellations, the name was shortened to Antlia.

Apus Sky Map

This constellation lies less that 20 degrees from the south celestial pole and is therefore invisible from most northern latitudes. If first appeared on star maps in 1603, in Johann Bayer’s famous Uranometria. Bayer gives credit for its discovery to several explorers of the Southern Hemisphere, including Amerigo Vespucci.

Aquarius sky map

Aquarius, one of the most ancient constellations in the sky, has been known under various names over the ages. It is located in a region of the sky that was known thousands of years ago as "the water" or "the sea". and is near other watery figures as Cetus, Pisces, Capricornus, Delphinus, Piscis Austrinus, and Eridanus. The constellation portrays a man or boy spilling water from an urn, although it is difficult to see any figure in the straggling assortment of mostly faint stars visible in the southern sky in the autumn.
Aquarius was at times identified with Zeus pouring the waters of life down from the heavens; sometimes the celestial river Eridanus is shown to have its source at the urn. Later Aquarius came to be identified with Ganymede, a beautiful young shepherd who was abducted by Zeus and taken to Mount Olympus to be the cup bearer to the gods. (The constellation Crater, is sometimes identified as Ganymede’s cup.) The constellation Aquarius was named by the Sumerians after their god of heaven An, who pours the waters of immortality upon the earth. Aquarius also figures in a very old Sumerian myth of a global deluge, thought to be the story that gave rise to the biblical story of the Flood. The name of several stars in Aquarius refer to good luck, probably because in ancient times the constellation’s solstitial rising occurred at the start of the rainy season and seemed to bring relief to the arid climes of the Middle East. Aquarius is the first constellation of both the Chinese and the Indian calendars and is again associated with water.

Aquila Sky Map

The constellation Aquila, identified as a bird since about 1200 B.C., is said to be the eagle that held the thunderbolts of Zeus, king of the gods, until he needed them. Aquila was sometimes sent on other errands by Zeus: It was Aquila that kidnapped the young Ganymede as he tended his flock on the slopes of Mount Ida and brought him to Olympus to serve as cup bearer to the gods.
The three brightest stars of Aquila figure in Indian mythology as footprints of the god Vishnu. In Japanese, Korean, and Chinese mythology the brightest star of Aquila, Altair, is identified as the herdsman, Ch’ien Niu, keeper of the royal herds. He fell in love with the maiden Chih Nu (called Tanabata in Japan), whose father was the sun king, the star we call Vega. Ch’ien Niu and Chih Nu married, but they were so in love that they neglected their duties, and the sun king banished them to spend their lives on opposite sides of the celestial river, the Milky Way. The are said to meet once a year, on the seventh day of the seventh month, when magpies stretch their wings across the river for one night - but only if the weather is clear. If it rains even the celestial birds cannot span the flood.

Ara Sky Map

The group of faint stars we now call Ara was once considered part of the constellations Centaurus and Lupus; it became separated from them when the modern constellation Norma was interposed. Its original Latin name, Ara Centauri, reveals this connection: Ara is the altar of the centaur Chiron. Half man and half horse, Chiron was believed to be the wisest creature on Earth. It was he who first brought order to the sky by showing mortals how to draw lines between the stars to form the constellations. Ara was also sometimes called the Altar of Dionysus. It appears on some old star maps as a tripod censer or brazier. Its H-like shape does not much resemble an altar. Early depictions portray it upright, with smoke from the altar rising northward into the Milky Way.

Aries Sky Map

The Egyptians of the New Kingdom (which began in the 16th century B.C.) identified this group of stars as a ram, an animal the associated with their principal god, Amon Ra. For the ancient Greeks, the group of stars represented the ram from which the Golden Fleece was taken. According to one myth, King Athamas of Thessaly had two children, Phrixus and Helle, by his first wife, who died when they were still very young. Athamas remarried, but, unbeknownst to him, his second wife hated the children and was cruel to them. The god Hermes took pity on the children and fashioned a magical ram, with wool of gold, to carry them to a land of safety. When the ram appeared to the children, the leapt on its back, and the ram flew into the sky, heading east. Helle lost her grip on the ram and fell into the body of water that separates Europe from Asia, which the Greeks called the Hellespont ("sea of Helle"; now known as the Dardanelles). Phrixus, though, was carried safely to Colchis, on the southeastern shore of the Black Sea, where he found refuge with king Aeetes. He sacrificed the ram and Aeetes hung it in a grove guarded by a sleepless dragon. There the Golden Fleece remained until it was stolen by Jason and the Argonauts.

Auriga Sky Map

Auriga was among the earliest constellations to be named, but its origins are not known. It is seen as a charioteer, usually identified with either Hephaestus (the Roman god Vulcan), or his son, Erechtheus, both of whom were lame. Each of these figures was credited by the Greeks with inventing the chariot to aid in his transportation. This group of stars has also long been associated with goat herds. In what may be a mix of the two associations, Auriga is usually portrayed with a goat over one shoulder, represented by the very bright star Capella, and with two or three kids on his arm. Capella was identified by the Greeks with Amalthea, the goat that nursed the infant Zeus. While playing with the animal the baby god broke off one of its horns, which he later imbued with the magical capability of dispensing great quantities of food and drink to whoever desired them - the cornucopia. In India, Capella was considered the ’heart of Brahma’, while natives of Peru called it Colca and also associated it with herders of flocks.

Bootes Sky Map

One legend says the Bootes, whose name comes from the Greek word for "ox-driver" or "herdsman", was the son of Demeter (Roman: Ceres), the goddess of agriculture. The constellation of Bootes was once also know as Arcturus. Bootes is credited with inventing the plow and was placed in the sky to honor his invention, of such immense importance to civilization. In another myth, Bootes was the son of Zeus and Callisto. Callisto, transformed into a bear by Zeus’s jealous wife, Hera, was in danger if being killed by her son Bootes, who was out hunting, until she was rescued by Zeus, who took her into the heavens. There Callisto became the constellation of Ursa Major, the Great Bear.

Capricornus Sky Map

Capricornus is one of the oldest constellations in the sky. Depiction’s of a goat, or of a goat-fish, have been found on Babylonian tablets around 3,000 years old. According to some ancient myths, Capricornus was the gate of the Gods, the portal in the sky through which the souls of mortals passed after they died. Capricornus is also identified with the lusty god Pan, who was known to be flighty. The story goes that Pan and some other gods were picnicking along the banks of the Nile. During their feast the monster Typhon came upon them. To escape Typhon the gods turned themselves into animals and fled. Pan panicked and was unable to decide what to become. Finally, he leapt feet first into the river. Just as half of him disappeared into the water, that half became a fish. The half that was above the water became a goat.

Centaurus Sky Map

Centaurus is one of two centaurs in the sky, the other being Sagittarius. Centaurus is said to be Chiron, the smartest and the wisest of his race, wiser even than the gods. He was skilled in the arts, hunting, and medicine. He was the tutor of such illustrious humans as Jason, Achilles, Hercules, and Asclepius. According to early Greek myths, it was Chiron who first fashioned the constellations and showed mankind how to read the sky. He placed a picture of himself in the sky to guide the Argonauts on their quest for the Golden Fleece. Chiron, created immortal, was accidentally wounded by Hercules with an arrow tipped in the venomous blood of the many headed serpent Hydra. Although he could not die, he was in excruciating pain. He pleaded with the gods to release him from the torture of immortality and offered a bargain: his own life for the release of Prometheus, the Titan who had stolen fire from the gods and given it to mankind. Finally, Zeus agreed and let Chiron die. Zeus wanted to place Chiron in the heavens to commemorate him, but by this time the whole northern sky was filled, so Chiron became Centaurus, far to the south and rarely seen in the northern sky.

Cepheus Sky Map

Cepheus was the king of an ancient land called Aethiopia. See the story of Andromeda.

About 243 B.C. Ptolemy Euergetes set out on a military expedition against the Assyrians, who had murdered his sister. Berenice, who was proud if her beautiful long golden hair, vowed to sacrifice her "amber tresses" if he returned victorious. When he did, Berenice, cut off her hair, and placed it in the temple of Aphrodite, goddess of beauty. That night the hair disappeared, enraging the king and the queen. To save the situation, and the lives of the temple priests, Conon the court astronomer, announced that Berenice’s gift had received such favor that Aphrodite had taken the hair and placed it in the sky for all to admire.

Corona Australis Sky Map

Corona Australis was one of the original 48 constellations named by 2nd century astronomer Ptolemy. It is said to be the crown worn by the centaur Chiron.

Corona Borealis Sky Map

In classical mythology, this constellation is known to be the crown of Ariadne. Ariadne was the daughter of Minos, king of Crete. Every year Minos levied a tribute on Athens, requiring that the city-state send home seven each of its most beautiful maidens and youths to sacrifice to the Minotaur, a creature that was half man and half bull. The Minotaur lived beneath the palace of Knossos in the infamous Labyrinth, a maze from which no one could escape. One year Theseus, son of the King of Athens, was among the youths. When Ariadne saw him she fell in love and secretly gave him a sword and a ball of string. Theseus unwound the string as he went into the Labyrinth, slew the Minotaur with the sword, and found his way out following the sting again. Theseus fled Crete with Ariadne, and on their way to Athens the couple stopped at the island of Naxos. Mysteriously, Theseus then abandoned Ariadne, who wept for her lost love. The god Dionysus in human form but wearing a crown, found her and fell in love with her. She refused to marry him, saying she was fed up with mortal men. Dionysus told her he was a god, but she did not believe him, whereupon he took off his crown and flung it into the sky. There its jewels began to sparkle as stars, forming Corona Borealis, a tribute to Ariadne. To the Shawnee Indians, Corona Borealis was a circle of star-maidens dancing in the sky. The circle is not complete because one of the maidens left to go to Earth to live with a mortal warrior, Algon. She later grew homesick and returned to the sky, taking along her son. Later still the sky gods agreed to bring Algon into the sky, In some legends he is thought to be the nearby star Arcturus. To the Arabs, these stars formed a cracked bowl or platter. To Australian aboriginals, this constellation was a boomerang.

Corvus Sky Map

According to myth, one day the god Apollo sent the raven Corvus for a cup of spring water. Near the spring Corvus spied a green fig, so he sat down and waited until it ripened. To explain his tardiness Corvus returned to Apollo with the cup (Crater ) of spring water, and a water serpent, Hydra, in his claws, claiming he had been attacked by the serpent and thus delayed. Apollo, seeing all, knew the truth and so banished all three to the sky. Corvus now sits within sight of the cup of water, but he can never drink, because it is guarded by the serpent. According to another myth Apollo had an affair with Coronis, the daughter of a king. They had a son, Asclepius, the founder of medical science, who was immortalized in the sky as the constellation Ophiuchus. Apollo became suspicious that Coronis was unfaithful to him and sent his spy, Corvus, then of silver plumage, to observe. Indeed, Corvus reported back, Coronis was having an affair. In a rage, Apollo slew Coronis, and consigned Corvus to Hades and turned his feathers black.  To the Arabs these stars were a tent.Mariners sometimes call them "the sail", for they resemble a gaff-rigged sail.

Cygnus Sky Map

Cygnus the swan, was not always a swan. Greek legend tells a tragic story of Apollo’s son, Phaeton, who tried to drive Apollo’s chariot across the sky. Apollo warned him not to drive to close to the Earth lest he set it on fire. Phaeton lost control of the wild horses, and to spare the Earth a fiery destruction, Zeus threw a lightning bolt at the young boy, killing him instantly. The horses climbed higher into the sky, scorching a path that became the Milky Way. Phaeton fell into the river Eridanus. Cygnus dove repeatedly into the river to try to retrieve the body of his friend but failed. Zeus was so impressed with Cygnus’ devotion to his Phaeton that he turned him into a swan, enabling him to dive more easily. Cygnus was eventually rewarded for his gallantry by a prominent place in the summer skies within the cloudy path of the Milky Way.

Delphinus Sky Map

One story has it that when Poseidon (Neptune) was courting the mermaid Amphitrite, he rode on the back of a dolphin. When she agreed to become his wife, Poseidon placed the dolphin in the sky in gratitude for his help. Herodotus relates another story, about the Greek poet Arion, who was exceedingly skilled at playing the harp like kithara. Periander, king of Corinth, sent Arion to Italy to play in a contest. Arion won the contest, and was richly rewarded, whereupon he chartered a ship to take him home. The crew, however, hoping to rob Arion of his treasure, attempted to throw him overboard. Arion asked to be allowed to play one last tune. He played so beautifully that he attracted a pod of dolphins to the ship, where upon Arion leapt overboard and landed on the back of one of them, who carried him home to Corinth. The seamen, thinking him lost, continued on to Corinth. Arion had arrived first and told Periander of their crime. When the ship arrived, Periander had the entire crew killed, and Arion’s prize money was returned. The gods placed a figure of a dolphin in the sky to commemorate the event.

Dorado Sky Map

Dorado is a modern constellation first appearing in Johann Bayer’s 1603 star atlas. Dorado contains the south ecliptic pole.

Draco Sky Map

Draco has stood for all the dragons of mythology, from Tiamat of the Sumerians to the monster slain by Saint George. In all myths the dragon symbolized anarchy and chaos. Draco’s origins probably rest with the ancient story of the Babylonian goddess Tiamat, who found herself challenged by the new gods. She created fearsome monsters to help her and in fact turned herself into a dragon. The hero Marduk defeated her by commanding strong winds to blow into the dragon’s mouth splitting her body. One half of Tiamat then became the sky, the other half became the earth. From that story the Greeks derived their myth of the battle of the ancient Titans with the newer gods of Olympus. In the conflict a dragon attacked Athena. She grabbed the creature and flung it up into the sky, where its body wound around the axis of the world, the celestial north pole. In another Greek story, Draco was the dragon that watched over the Golden Apples of the Hesperides, the procurement of which was one of the Twelve Labors of Hercules.  To the ancient Indians Draco was a crocodile. To the ancient Egyptians it was a crocodile or a hippopotamus. The constellation has even been identified with a dragon from the German epic the Nibelungenlied.

Gemini Sky Map

In classical mythology, these stars represent the twins Castor and Pollux, who were hatched from an egg borne by Leda after she was seduced by Zeus in the guise of a swan. Their sister was Helen of Troy. In ancient Rome Castor and Pollux were sometimes confused with Romulus and Remus, legendary founders of Rome. The twins were raised by the wise centaur Chiron, represented by the constellation Centaurus, and later joined Jason, also brought up by Chiron, when he set out on the Argo in search of the Golden Fleece. In commemoration of their helping to calm a terrible storm during the voyage, Castor and Pollux are sometimes considered the patrons of mariners. In China the two stars we call Castor and Pollux are associated with yin and yang, the dual forces of nature.

Hercules Sky Map

In Greco-Roman mythology, Hercules is the half mortal son of Jupiter (Zeus) and the princess Alcmene. Jupiter’s ever jealous wife Juno (Hera) sent serpents to kill the baby Hercules in his crib. The child, with astonishing strength, managed to strangle them, and grew up to become the strongest of men. Thanks to the scheming of his hateful stepmother, Juno, Hercules became indentured to King Eurystheus. To gain his freedom he had to perform the famous Twelve Labors, the first of which was to kill the Nemean Lion, a fierce creature of impenetrable hide who had fallen from the Moon and was laying waste to the valley of Nemea. Hercules succeeded in strangling the beast, whereupon Jupiter place the lion in the sky as the constellation Leo. Hercules’ next task was to kill the many headed monster, the Hydra, which also became a constellation. Among his other challenges was subduing the Cretan Minotaur, who some say is the origin of the constellation Taurus. After his release from servitude the tireless Hercules accomplished many other noble deeds. One myth credits him with killing the eagle that devoured the liver of the Titan Prometheus who had stolen fire from the gods and given it to humankind. Later Hercules later won the hand of the beautiful maiden Deianeira. One day she was kidnapped by the centaur Nessus, but Hercules, hearing her cries, shot the centaur with an arrow. Dying, Nessus gave Deianeira a drop of his blood, telling her, untruthfully, that a touch of it would restore Hercules’ love if his affections ever strayed. Later, thinking her husband was losing interest in her, Deianeira put the drop on his tunic. When Hercules donned the garment, the blood burned into his skin, causing him terrible torment. Seeing what she had done, Deianeira hanged herself, and Hercules, in anguish, incinerated himself. His father, Jupiter, then placed him in the sky.

Hydra Sky Map

Hydra was a many headed monster slain by Hercules as one of the Herculean tasks. This was not an easy task since each time Hercules cut off a head of the Hydra, two more heads grew in the severed head’s place. As a solution to this problem, Hercules used a torch to cauterize each stump after he cut off that head. One head was immortal, so when Hercules cut that one off, he placed it under a huge stone where it could do no harm. After the battle, Jupiter (Zeus) placed the Hydra in the sky. Hydra is the largest constellation in the sky.

It is said that Hippocrates, the famous Greek physician and the father of medicine was his 15th grandson. According to legend, of day Asclepius killed a snake, but to his surprise another snake arrived and revived its companion with herbs. As his medical skills grew, Asclepius even learned how to revive the dead. This knowledge worried Hades, god of the underworld, who feared that his domain would not receive any new souls. Hades persuaded his brother Zeus to kill Asclepius with a thunderbolt and to decree that all mortals must one day die. Zeus did strike Asclepius dead, but to honor his skills as a healer Zeus placed Asclepius in the sky with his serpents.

Orion Sky Map

In Greco-Roman mythology, the character Orion was a famed hunter, but he was boastful and went so far as to claim that no beast could kill him. To teach Orion a lesson, the goddess Hera sent a tiny scorpion to sting him. Orion smashed the scorpion with his club but not before it had stung him fatally. Orion and the scorpion were placed in the heavens on opposite sides of the sky. When Scorpius rises, Orion sets, and vice versa; these enemies are never seen together in the sky. In another legend Orion, the son of Poseidon, was said to have been a great hunter. Artemis, goddess of the Moon and the hunt, fell in love with him and neglected her duties of lighting the night sky. Her fellow gods and goddesses pleaded with her to no avail. One day her twin brother, Apollo, the sun god, saw Orion bathing in the seas far out from shore. Apollo shined the light of the sun so brightly that Orion became just a dark blur among the brilliantly sparkling waves. Apollo then called his sister and challenged her to hit the black shape so far from shore with here arrow. In pride and anger Artemis shot her arrow, striking the object directly. When Orion’s body later washed ashore, Artemis realized what she had done. In grief she took his body and placed it in the sky, together with his hunting dogs, and marked it with bright stars. Having slain her lover, she was inconsolable and lost all interest in life; and that is why, ever since, the Moon has been cold and lifeless. Orion, however, quite quickly recovered and to this day he chases the Pleiades - seven lovely nymphs found in the constellation Taurus - around the sky, just as he had chased them on Earth.

Perseus Sky Map

In Greek myth, Perseus was the son of Zeus and the mortal Danae. Danae’s father, having been told by an oracle that his grandson would on day kill him, set Danae and Perseus adrift in a trunk. They were rescued by a fisherman and went to live on his island. The king of that island, Polydectes, wished to court Danae, and to get Perseus out of the way he sent the youth to slay the Gorgons, three sisters so ugly that any mortal who beheld them turned to stone. The night before his departure, Minerva appeared to Perseus in a dream and gave him a shiny magic shield upon which he could look at Medusa’s reflection without being harmed. She also gave him a magic sword with which to sever the neck of Medusa. A man made sword would not do the job. Then Mercury appeared and gave Perseus winged sandals so that he could fly across the ocean to the island where the Gorgon lived in a cave. During his quest, Perseus found the three nymphs of the North, who gave him a magic helmet that would make him invisible and a magic pouch into which to place the severed head. Armed with the magic of the gods, Perseus found the island of the Gorgon Medusa. Her cave was guarded by two sisters who never slept. Perseus donned his helmet and crept quickly past them. Medusa lay asleep on the floor of the cave. Perseus raised his shield high and, watching her reflection in the dim light, he backed up to her. Then, with on mighty blow of the sword, he severed the head of Medusa. He picked up the head and placed it in the pouch. As he left the cave and walked down to the shore, a trail of blood was left behind. From Medusa’s spilled blood, Pegasus was born. Perseus mounted the winged horse and headed back to Greece. Fleeing the other Gorgons, Perseus came upon King Atlas, who refused him aid. Glancing at the head of Medusa, Atlas turned into a mountain of stone and thereafter had to bear the weight of the heavens on his shoulders. Continuing his flight, Perseus came upon the princess Andromeda, the chained maiden, and rescued her from Cetus, the sea monster. Later in his life, Perseus, throwing the discus in an athletic contest, struck and killed a spectator. That unfortunate being turned out to be his grandfather, and the prophecy that he would be killed by his grandson was fulfilled, in spite of all the old man’s efforts.

Ursa Major Sky Map

Our best known legend about Ursa Major comes from Greek mythology. According to this legend, the king of the gods, Zeus, fell in love with a beautiful woman named Callisto. When Zeus’ wife Hera learned of the affair, she changed Callisto into a bear. This bear roamed the forest until one day she happened upon a young and handsome hunter whom she recognized as her own son, Arcas. Callisto raised up on her hind legs to embrace her child, but Arcas saw only a bear and raised his spear. In the nick of time, Zeus intervened, changing Arcas into a bear. Then he grasped Callisto and her son by their tails and flung them into the sky, to become our constellations of the large and small bears. This explains why the celestial bears have such long tails, in contrast to their earthly counterparts. Some North American Indian tribes saw things differently. They also pictured bears in Ursa Major, and the nearby constellation Ursa Minor, as evidenced by the names frequently used to describe them, Okuri and Paukuawa - both meaning "bear".  But in Iroquois mythology, all bears once had long tails. The earthly bear lost its tail attempting to show it off, using the tail to fish through a hole in an iced over lake. The bear’s tail froze and fell off, and now all Earthbound bears mimic this ancient bear with its stumpy tail. A Blackfoot Indian legend tells of an elder daughter of a large family. The daughter fell in love with a grizzly bear. Her father was furious and ordered her brothers to kill the bear. But this was a magical bear, and before the bear died he gave some of his magic to his bride. She then turned herself into a grizzly bear, and in retaliation she destroyed her entire village, killing her mother and father. She began chasing her eight brothers and sisters, but one brother had magic of his own. He shot an arrow into the sky, and instantly all eight children followed it to become stars. The seven oldest children became the seven stars forming the Big Dipper. The youngest child was frightened, and she can be seen as the dim star Alcor, huddling close to the star Mizar.
