Andromeda was chained to a rock by the sea as an offering to Cetus

Andromeda is a central figure in Greek mythology. She is best known for her link with the hero Perseus and for the story of her rescue from a sea monster. Her tale is about beauty, pride, the anger of the gods and heroism.

Parentage

Andromeda was the daughter of Cepheus, king of Aethiopia, and his queen, Cassiopeia. This Aethiopia is a region of myth, not modern Ethiopia.

Cassiopeia’s vanity set Andromeda’s story in motion. She claimed she was more beautiful than the Nereids, the sea nymphs.

The offense and punishment

The Nereids took offense at Cassiopeia’s boast. They appealed to Poseidon, god of the sea. To punish the queen’s arrogance, Poseidon sent a sea monster, Cetus, to ravage the kingdom.

An oracle declared there was only one way to calm Poseidon and save the kingdom. Andromeda had to be sacrificed to the monster.

The sacrifice

Andromeda was chained to a rock by the sea as an offering to Cetus. She waited for her fate, helpless and exposed, as the monster came near.

The rescue

Perseus, a Greek hero and son of Zeus, was on his way back from killing Medusa when he came upon Andromeda.

He was struck by her beauty. He offered to rescue her if she would become his wife. Cepheus and Cassiopeia agreed.

Perseus used Medusa’s severed head, whose gaze turned creatures to stone, to defeat Cetus. He freed Andromeda and took her as his bride.

The wedding

The marriage of Perseus and Andromeda brought conflict. Andromeda had already been promised to Phineus, her uncle. At the wedding feast, Phineus and his supporters attacked Perseus.

Perseus used Medusa’s head again and turned Phineus and his allies to stone. That secured his marriage to Andromeda.

Later life

Perseus and Andromeda had several children. According to Greek mythology, one of them was Perses, the ancestor of the Persian people.

After her death, Andromeda was placed among the stars. She became the constellation Andromeda, next to Perseus, Cassiopeia, Cepheus and Cetus.

Symbolism

Andromeda’s beauty: It stands for the danger of vanity and pride, since her mother’s boast caused Andromeda’s plight.

Heroism of Perseus: It shows the hero as savior and protector.

Cosmic legacy: Her change into a constellation ties her story to the heavens. It stands for immortality and the favor of the gods.

Children

In Greek mythology, Perseus and Andromeda had several children. They are often noted for founding dynasties and for their links to myths and ancient cultures. Here is a closer look at the children and their meaning.

1. Perses

• Role in mythology: Perses is seen as the ancestor of the Persian people. According to Greek mythology, he stayed in the kingdom of Cepheus and founded the Persian royal line.
• Symbolism: The story of Perses shows the Greek effort to link their myths to the histories and origins of other cultures, including the Persian Empire.

2. Alcaeus

• Role in mythology: Alcaeus is sometimes named as a son of Perseus and Andromeda. He plays a smaller role in the surviving myths.
• Significance: Alcaeus may have been linked to early Greek dynasties or to the heroic line that led to Heracles (Hercules).

3. Heleus

• Role in mythology: Heleus is another son attributed to Perseus and Andromeda. As with Alcaeus, the myths say little about him directly.
• Significance: Heleus is sometimes connected to regions or peoples of Greece. This supports Perseus’s status as a founder-hero.

4. Sthenelus

• Role in mythology: Sthenelus became a king. He matters in later myths as the father of Eurystheus, the king who set Heracles his Twelve Labors.
• Significance: Through Sthenelus, Perseus’s family stays present in later Greek myth and hero stories.

5. Gorgophone

• Role in mythology: Gorgophone is one of the daughters of Perseus and Andromeda. Her name means “Gorgon-slayer,” a direct reference to Perseus’s defeat of Medusa.
• Significance: She married Perieres, son of Aeolus, and after his death Oebalus. Pausanias says she was the first woman to marry a second time, since widows had until then stayed unmarried.

6. Electryon

• Role in mythology: Electryon became king of Mycenae. He has a key place in the family tree of Greek heroes. He was the grandfather of Heracles through his daughter Alcmene.
• Significance: Through Electryon, Perseus’s line leads to Heracles, one of the greatest Greek heroes.

Other notes

• Mythological function: The children of Perseus and Andromeda often link the mythical and historical worlds. They join Greek myth to the family trees of other cultures and heroes.
• Dynastic importance: The descendants of Perseus and Andromeda, Heracles among them, became central figures in Greek hero tales. They stand for divine favor and heroism carried on in human history.

The children of Perseus and Andromeda link the mythical past to what the Greeks saw as their history.

Astronomical connection

The Andromeda constellation lies in the northern sky, near the constellations Perseus and Cassiopeia.

The ancient Greeks named the Andromeda constellation after the figure from their mythology. The constellation is part of the story of Andromeda, Perseus and the sea monster Cetus. The name is traditionally credited to ancient Greek astronomers such as Eudoxus of Cnidus (about 4th century BCE) or Hipparchus (2nd century BCE). They included it in their star catalogues.

Later, the constellation was formally recorded and passed on through works such as Ptolemy’s Almagest (about 2nd century CE), which lists Andromeda among the 48 classical constellations.

The names and associations were kept through the Roman period and into modern times.

Today Andromeda is one of the 88 constellations officially recognized by the International Astronomical Union (IAU). Its name comes from Greco-Roman mythology.

The Andromeda Galaxy, the nearest major galaxy to the Milky Way, is named after this constellation.

The story of Andromeda becoming a constellation appears in Greek mythology. No single ancient Greek writer is credited with the whole story of her transformation. It is a composite story that several ancient authors refer to.

Hyginus (Astronomica): Hyginus was a Roman author. He collected myths and constellations in his work Astronomica. In Book II he describes the constellations, including Andromeda, and how the gods placed her in the stars.

Placed among the stars by Minerva

Hyginus says Minerva set Andromeda among the stars for the valor of Perseus.

They say she was put among the constellations by the favour of Minerva, on account of the valor of Perseus, who freed her from danger when exposed to the sea-monster.

Hyginus, Astronomica 2.11

Aratus (Phaenomena): Aratus was a Greek poet. He wrote Phaenomena, a teaching poem about constellations and events in the sky. It refers to the mythical figures in the sky. Andromeda is not described at length, but the poem describes Perseus and other related constellations.

The head of Andromeda is setting and against her is brought by the misty South the mighty terror, Cetus

Aratus, Phaenomena

Pseudo-Eratosthenes (Catasterismi): This work is attributed to Eratosthenes or to a later writer. It explains many constellations, including Andromeda, and links them to their origins in myth.

After her death, Athena placed Andromeda among the stars, fastening her in the same position in which she had been bound.
