Pierre Le Monnier's "Constellation du Solitaire" in the History of the French Academy of Science publication (1776)

This French term was used for the now-obsolete constellation Turdus Solitarius (= Solitaire = Noctua).

Etymology and History

The extinct constellations Turdus Solitarius and Noctua, which share some history and region of the sky, have brief summaries in Star Names - Their Lore and Meaning by Richard H. Allen (1899, pp. 418-419) and in Star Tales by Ian Ridpath (1988, p. 151) and have a dedicated chapter in The Lost Constellations by John C. Barentine (2015, ch. 29, pp. 449-464).

The classical constellation Hydra ends with the star Pi Hydrae. In early modern time, some astronomers extended the chain of stars towards Libra and even introduced yet another bird on its longer end (as traditionally, the Raven sits on the tail tip of Hydra). The constellation of "Solitaire" was first depicted in Pierre Charles Le Monnier's contribution to the Histoire de l'Académie royale des sciences ... avec les mémoires de mathématique & de physique... tirez des registres de cette Académie, from the French Academy of Science (Académie royale des sciences, Paris) 1776.

Ian Ridpath elaborates that the engraver Yves-Marie Le Gouaz (1742–1816) accompanied Pierre Le Monnier's announcement of the new constellation and states:

Unfortunately the bird shown on the engraving is not the Rodrigues solitaire as Le Monnier had intended, but rather a blue rock thrush, known as the solitaire of the Philippines. Whether the error was due to Le Monnier or Le Gouaz is unknown.

Bode (1801) in his famous Uranographia takes over the idea of this additional bird but depicts it slightly differently. His label in Latin is "Turdus Solitarius" which is the scientific term for the Blue Rock Thrush, first described in Carl von Linné (Carl Linnaeus): Systema Naturae[1][2] (10th edition 1758).

Translations

In "Kenntniß zu Anleitung des Gestirnten Himmels" (in German), Bode 1805 refers to it as "der Vogel Einsiedler" - "the hermit bird". When talking about Le Monnier's original constellation, Jamieson (1822) refers to it as "L'Ermite Oiseau" - never referring to it as either Solitaire or Turdus Solitarius.

Species of Bird

The bird was native to the Rodrigues Island, east of Madagascar & east of Mauritius in the Southern Indian Ocean. It is considered a species of doves and pigeons although they were flightless and much taller (size of the swans). The Rodrigues Solitaire is considered an endemisms that derives from Madagascar pigeons, while the Dodo is considered an endemism of the same pigeon at another island (Mauritius).

Emoji

The description reads:

A brown or gray dodo shown in full profile. Generally depicted with a curved yellow beak, small wings, a fluffy white tail, yellow or orange feet, and black talons.

May be used to represent dodos or the concept of being extinct.

Dodo was approved as part of Unicode 13.0 in 2020 and added to Emoji 13.0 in 2020.

Unicode: U+1F9A2

IAU Working Group Star Names

The brightest star of historical "Turdus Solitarius" was Sigma Librae, mag. 3.2, named Brachium by WGSN. It was suggested in 2023 to try naming another of its stars, if we can identify them reliably. The French "Solitaire" is an obvious name to use. The biological relative from the neighboring island, the Dodo, is much more popular and even has an emoji. Perhaps we should use this name, too and commemorate extinct animals. Or maybe use a double star for both, Solitaire and Dodo?

Suggestions:

  • E Hya (4.41 mag, SIMBAD) is the second brightest star in the constellation, and is within the area of the bird in both versions, but not drawn in Monnier's map
  • m Hya (5.05 mag, SIMBAD), HIP 72197 = HR 5497, is "double or multiple".
    • m Hya A has 5.46 mag - suggested name "Solitaire"
    • m Hya B has 7.25 mag - suggested name "Dodo"
  • HIP 75939 (6.2 mag, SIMBAD) "the one in the bird's eye".

The name was discussed and approved by the IAU WGSN in 202x. The WGSN chose ... (not to apply/ to apply the name to a neighbouring star/ to ...) in the IAU-CSN.
