Hygieia Mythology

Daughter of Asclepius and the keeping of health

Hygieia is the tenth asteroid, found by Annibale de Gasparis at Naples on 12 April 1849. It is about 430 kilometres across and the fourth largest body of the belt. Observations showing its surface to be rounder than expected opened a debate about whether it should count as a dwarf planet.

It is named after Hygieia, the goddess of health. In classical astrology Hygieia has no rulership, exaltation, sect or joy. This page tells the myth of the goddess and her place in ancient temple medicine.

Key facts

Symbolism map: health, protection and temple medicine

The glyph of Hygieia stands at the centre. The branches around it show the symbolism in four colours: goddesses in gold, archetypes in blue, traditions in green and narratives in red. Touch a branch and its explanation opens below the map.

HygieiaHealth itself

The name Hygieia simply means health, so the goddess personifies a condition. Pausanias names her as the daughter of Asclepius, while some local traditions make her his wife. Statues show her feeding a serpent from the bowl in her hand.

AsclepiusThe physician father

Asclepius is the son of Apollo and Coronis and was raised by the centaur Chiron. Because he began to raise the dead, Zeus killed him with a thunderbolt and he was later taken up to the sky. His temples spread from Epidaurus to Pergamon. Asclepius on the Chiron page →

Five sistersPanacea, Iaso, Aceso, Aegle

The daughters of Asclepius are Hygieia, Panacea, Iaso, Aceso and Aegle. Their names mean health, all healing, cure, remedy and brightness. Together the five name the stages of an illness one by one.

Keeping and curingTwo separate tasks

Panacea is the goddess of recovering from illness and Hygieia of not falling ill. Ancient medicine kept the two apart and assigned regimen, meaning diet and exercise, to Hygieia. That distinction is the oldest counterpart of modern preventive medicine.

The bowl and the serpentThe Bowl of Hygieia

In her images the goddess holds a bowl with a serpent feeding from it. The serpent sheds its skin and so stands for renewal, while the bowl stands for the prepared remedy. The pair is used today as the symbol of pharmacy.

The Hippocratic OathThe opening line

The oath begins, 'I swear by Apollo the physician, by Asclepius, by Hygieia and by Panacea'. The text dates to the fifth or fourth century BC. Naming Hygieia there shows that keeping health counted as part of the physician's work.

EpidaurusThe temple of sleep

At the Asclepieion of Epidaurus the sick slept in the temple and were treated in their dreams, a practice called incubation. Inscriptions on the temple walls record the names of those who recovered and their complaints.

Athena HygieiaAn epithet on the Acropolis

On the Athenian Acropolis Athena was worshipped under the title Hygieia and had an altar beside the Propylaea. Plutarch reports that a workman who fell during Pericles' building works was healed by a herb the goddess showed. Here health is not a separate goddess but an aspect of Athena.

SalusThe Roman counterpart

In Rome Salus means both health and the safety of the state. Her temple on the Quirinal was dedicated in 302 BC. When the Greek Hygieia reached Rome she merged with this older goddess.

Regimen and measureThe daily order

Hippocratic texts explain health through the balance of food, sleep, exercise and climate. That order is called diaita, regimen, and it is the physician's first instrument. Hygieia is the goddess of this daily measure rather than a miraculous rescuer.

The word hygieneA term from the goddess

The French hygiène entered the language in the sixteenth century through the Greek hygieinos. The word carries the name of the goddess directly. Its present sense is limited to cleanliness, while the ancient sense covered the whole order of life.

The discovery by de GasparisNaples, 1849

Annibale de Gasparis found nine asteroids at the Capodimonte Observatory, and Hygieia is the largest of them. The name was proposed by the observatory director Ernesto Capocci. It was the last of the large belt bodies to be noticed, because its surface is dark.

The dwarf planet debateRound or not

Observations in 2019 showed Hygieia to be rounder than expected. The definition of a dwarf planet requires a body rounded by its own gravity, which opened its classification to debate. The International Astronomical Union has not yet ruled on it.

Hygieia in modern astrologyTwentieth century

Those who use Hygieia connect it with preventive health, diet and habit. Its literature is thin compared with the four large asteroids. These readings have no link to the classical system of dignities and cannot be added to it.

Meaning of the glyph:

There is no standard Unicode sign for Hygieia. The glyph on this page is taken from her oldest images: the bowl she holds and the serpent feeding from it. The same pair is used today as the symbol of pharmacy.

∪ The bowlThe vessel in the middle is the bowl in her hand and stands for the prepared remedy.
∼ The serpentThe curved line above is the serpent reaching the bowl, and it stands for renewal through the shedding of skin.
| The footThe foot and base below hold the bowl upright and stand for the continuity of the regimen.

The goddess of health across cultures

Every culture has a deity of health, but keeping and curing are not everywhere separated. The counterparts below rest on similarity of function and their limits are stated.

Greek

Hygieia

Daughter of Asclepius, standing for the keeping of health. She was worshipped with her father at Epidaurus, Athens and Pergamon.

Roman

Salus

She means both personal health and the safety of the state. The Greek Hygieia merged with her on arrival in Rome.

Mesopotamian

Gula

Goddess of healing, shown with a dog. That she both sends and removes disease differs from the Greek division.

Egyptian

Sekhmet

The lion headed goddess who sends and stops plague. Her priests counted as physicians; the protective side matches Hygieia, the punishing side does not.

Indian

Dhanvantari

God of Ayurveda, who rises from the churning of the ocean holding the vessel of amrita. The motif of the vessel resembles Hygieia's, while the origin is separate.

Norse

Eir

Named in Snorri's list as the best of physicians. Little is known of her, so the comparison holds only at the level of the name.

Celtic

Sirona

A goddess linked with healing springs and shown holding a serpent. The Romans paired her with Apollo Grannus.

Three myths

The daughter of the physician god

Asclepius is the son of Apollo and Coronis and learns medicine from the centaur Chiron. His art advances so far that he begins to raise the dead, and Zeus kills him with a thunderbolt to protect the order of things. After his death he is taken up to the sky as the constellation Ophiuchus. Among his daughters Hygieia stands out as the one worshipped beside her father, and temple inscriptions name the two together.

Healing through sleep

At the temple of Epidaurus the sick slept in the hall called the abaton, waiting for the god to appear in a dream and show the treatment. In the morning the priests interpreted the dream and set the regimen. Inscriptions found at the site record the name of each person healed, the complaint and the dream. These records show ancient medicine resting on both belief and observation.

The herb on the Acropolis

Plutarch tells that during the building of the Propylaea under Pericles the best workman fell from a height and the physicians gave up hope. Pericles saw Athena in a dream, the goddess showed him a herb, and the man recovered with it. Pericles then set up a bronze statue on the Acropolis for Athena Hygieia. The story is a case where health is tied not to a separate goddess but to the city's own.

Hygieia in classical astrology: no rulership

RulershipNone. In classical astrology domicile belongs to the seven traditional planets alone.
ExaltationNone. Degrees of exaltation are defined for the seven planets.
SectNone. The division by sect belongs to the classical seven.
JoyNone. Joy is tied to the house system and does not cover asteroids.
Type of bodyAsteroid, about 430 kilometres across. Whether it counts as a dwarf planet is disputed.
Discovery12 April 1849, Annibale de Gasparis, Naples.
OrbitIt circles the Sun in about 5.6 years.
Modern useIts ephemeris is available in common software. Its interpretation belongs to modern asteroid literature.

The position of this school is plain: Hygieia is not a planet and rules no sign. It has no place in the dignity table. For the detail see Essential and Accidental Dignities.

Frequently Asked Questions

What is the difference between Hygieia and Panacea?

Panacea is the goddess of recovering from illness and Hygieia of not falling ill. Ancient medicine kept the two apart and gave the order of food and exercise to Hygieia. The name of Panacea survives in the word panacea.

Is the bowl and serpent of the pharmacy sign hers?

Yes, the bowl with a serpent feeding from it comes from her images. The rod of Asclepius, with a single serpent, is a separate symbol. The two are often confused.

Does Hygieia rule a sign in classical astrology?

No. It is an asteroid found in 1849 and holds no dignity in the classical system.

Is Hygieia a dwarf planet?

Not yet. Observations in 2019 showed it rounder than expected and opened the debate, but the International Astronomical Union has not changed its classification.

Should I look at Hygieia in my chart?

In this school the reading is built from the seven planets. Asteroid positions can be seen out of curiosity, but reading them like planets breaks the system of dignities.
