Pronunciation

  • Ecclesiastical: [kon.stelˈlat.t͡si.o][1]

Forms

cōnstēllātiō f (genitive cōnstēllātiōnis); third declension[1]

Etymology

It is formed from Latin con- + stēlla (“star”) + -ātiō.[2][3] The noun stēlla goes back to Proto-Italic *stērlā-, which de Vaan takes as an Italo-Celtic formation whose root is Proto-Indo-European *h₂ster- (“star”).[4]

Earliest recorded meaning

Firmicus Maternus, in his 4th-century handbook of astrology, uses it for the position of the stars that was held to shape human fate.[3][5]

Semantic evolution

In Late Latin it was a word of astrology: the arrangement of the stars at the moment of someone's birth, and so a horoscope.[6][3][7] Augustine, arguing against belief in fate, explains that people call the noting of the stars' positions at a birth constellationes.[2]

In Medieval Latin it kept the astrological sense[8][9] and also named a group of stars, a constellation in the modern sense, and a chance coming together of circumstances.[10][5] English took it over, partly through Old French, first for the position of a planet in the zodiac.[11]

Timeline

  • 343/350 AD – Firmicus Maternus uses it in his astrological work.[3][5]
  • c. 390 AD – Ammianus Marcellinus speaks of casting the emperor's horoscope (constellationem principis colligere).[12][7][5]
  • 354–430 AD – Augustine explains the constellationes of the astrologers.[2][5]
  • 639–709 AD – Aldhelm writes in his verse on virginity: si fors aut fatum seu constellatio quicquam est (“if chance or fate or the stars are anything”).[9][5]
  • early 14th century – English borrows it as constellation for the position of a planet.[11]
