===Lilium Constellation === |
|||
Ignace-Gaston Pardies introduced a new (now obsolete) constellation ''Lilium'', the fleur-de-lis of France, on plate 2 of his ''[https://gallica.bnf.fr/ark:/12148/btv1b59714416/f2.zoom Globi coelestis in tabulas planas redacti descriptio]'' atlas published posthumously in 1674, although he did not attach a name to the image. He had reused four stars in the north of Aries from which Petrus Plancius in 1613 had previously formed Apes, the Bee to model the constellation. |

In 1679, Augustin Royer published his ''[https://gallica.bnf.fr/ark:/12148/bpt6k58185917/f6.planchecontact Cartes du ciel réduites en quatre tables]'' and an accompanying [https://archive.org/details/cartesducielredu00roye/page/88/mode/2up star catalogue], both of which contain the constellation Lilium, this time carrying the name and the translation "La Fleur de lys". |

Si l’on prend le triangle & la tête de Méduse pour les deux extrémités de la base d’un triangle équilatéral dont le sommet seroit au Midi, on remarquera trois étoiles dont une est de la troisieme grandeur, c’est la petite Constellation de la Mouche, ou le Lys.</blockquote>English translation:<blockquote>'''The head of Medusa''' To the east of the triangle we see a group of five stars, forming the head of Medusa; the easternmost is of the second magnitude, and is called Algol; this star is singular in that it diminishes in magnitude and luminosity in the period of 2 days 20 hours 49 minutes 1 second. If we take the triangle and the head of Medusa for the two extremities of the base of an equilateral triangle whose summit would be at Midday, we will notice three stars of which one is of the third magnitude, it is the small Constellation of the Fly, or the Lily.</blockquote> |

The modern designations of these two stars are 39 and 41 Arietis. In 2017 the IAU WGSN adopted Lacaille’s name Lilii Borea for 39 Arietis. They gave 41 Arietis the name Bharani after the second nakshatra (lunar mansion) in Hindu astronomy, consisting of 35, 39, and 41 Arietis. |

In his short list of right ascensions of selected stars and his star catalogue, Lacaille 1757 named this star "The one south of the Lily" (or "the southern one of the Lily") in Latin: Lilii Austrina. The Lily (Lilium) is an obsolete constellation of the 17th century. It was formed of four stars that were unnamed in antiquity: In the Almagest they were listed as "The 4 stars over the rump [of the Ram]", outside the constellation image.
