Context of feminine creation

Aglaonice was the first woman known to have devoted herself to the study of astronomy. However, in ancient Greece, many women played an important role in different fields of knowledge, such as Phanostrate, midwife and physician; Pythias of Assos, biologist and embryologist who collaborated with her husband, Aristotle, in studies on embryology and in the preparation of an encyclopaedia on Natural History; Agnodica of Athens, an important gynaecologist; Artemisia II of Caria, expert in medicinal herbs; her namesake Artemisia I, also queen of Caria and captain of a fleet; Aspasia of Miletus, philosopher, logographer and teacher of rhetoric; Hypatia of Alexandria, mathematician and astronomer, among many others.

Review

Known as "she who makes the moon disappear", she is mentioned in the writings of Plutarch and in the scholia of Apollonius of Rhodes as an astronomer and as the daughter of Hegetor (or Hegemon) of Thessaly. However, her scientific authority was called into question because of the ideas transmitted by Aristotle. Thus, her supernatural powers were preferred to her mathematical and celestial observation skills, which enabled her to predict the time of a lunar eclipse. She is now considered the first European astronomer on record.

Justifications

  • One of the first female astronomers who mastered the art of predicting lunar eclipses and to whose research we owe the knowledge of the causes and timing of lunar eclipses.
  • She is now considered the first European astronomer on record.

Biography

Daughter of Hegetor (or Hegemon), she lived in Thessaly and it is deduced that she studied in Mesopotamia, as she knew perfectly the cycles of the eclipses of Saros, which the Chaldean people knew, and with which she could predict, from the Babylonian tablets and the observation of astral movements, the lunar eclipses with great precision for the time.

Aglaonice developed her activity together with other women who together were called "the witches of Thessaly". A land that was known to be home to some of the most powerful sorceresses of the time, and where an important cult of Hecate developed. The collective imagination, without the knowledge that these women enjoyed, ended up harbouring the belief that they could hide the moon. Thus, officially, she was considered a sorceress or priestess for her supposed ability to make the moon disappear from the sky, which has been interpreted as being able to predict the time and region in which a lunar eclipse was to take place.

In fact, it was her knowledge of the metonic cycle and her great mathematical ability and observation of celestial phenomena that enabled her to predict eclipses so accurately. But the ideas conveyed by Aristotle, in particular those referring to the supposed inferiority, including intellectual inferiority, of women, called into question her scientific authority, and it was preferred that she be considered a witch or a priestess.

She now occupies a place in the history books as the first astronomer in ancient Greece.  

One of the craters of Venus is named Aglaonice in her honour and she is also a character in Jean Cocteau's film Orpheus, where she appears as a friend of Eurydice and leader of the League of Women.
