ARTICLE
Some constellations in the Western sky have been gone over time.
Until 1922, the year when astronomers agreed there were 88 constellations in the sky, the stars had been represented in several ways throughout centuries. In Western classic depictures, they were mentioned as being part of mythological figures, which became the usual way to allude to them during the following centuries.
Many cartographers considered Claude Ptolemy's stars catalogue Almagest from the middle I c. b.C. as the foundation for their works, a document that included observations made from the Greek Mediterranean Sea. Cartographies depicted stars mostly as seen from Earth, although Albrecht Dürer's charts (1515), Peter Apian's astrolabe (1540) and Johannes Hevelius' atlas (1690) were exceptions, since they represented them as seen from space, like celestial globes do. Dürer's works were also distinctive since were the first ones to display the Milky Way path, and even on charts seeming the current way to draw Western astrological charts: the Zodiac was placed around a rim (the center was the celestial pole on the maps), counter-clockwise, and dividing the whole area into 30° segments.
Catalogues were based on registries made from different locations on Earth, like the Mediterranean Sea, Greenwich (England), Shīrāz (ancient Persia in Iran), Madagascar and Cape Town (Africa), Sumatra (Asia) and Saint Helene islands (Atlantic Ocean). Astronomers didn't just update positions but also included more stars, which made them introduce new constellations to include them. However, not all of astronomers approved those created by others, and sometimes they didn't depict them in their atlases.
With or without recognition, the Earth's axis motion always changes the view of locations, which is better noticed the more centuries pass by from one observation until the next one. So it seems some stars are "getting closer to" or "moving away from" each other, a seeming change making cartographers move them from one constellation to another one, which made disappear some figures whereas new ones were created. Another reason to change their locations was to avoid overlaps as other ones were added.
Mythological drawings were the main reference although some cartographies progressively included elements that provided more accurate ways to identify stars. For instance, there were mentioned before Dürer's radial lines at 30° intervals, whereas Johann Bayer was the one who assigned Greek letters to stars in the XVII century to indicate brightness, as well as depicted them on grid plates with calibrated margins to allowing to specify degrees. In the following century, Alexander Ruelle was the one who connected them with lines. In the XIX century, Johann E. Bode registered by the naked eye over 17,000 stars in over 100 constellations, and also drew boundaries lines between them (although extremely soft). Finally, at the end of the same century, the Belgian Eugène Delporte traced zigzag boundaries for stars to stay inside the constellation they were assigned to, according to their passage across meridians and declination, leaving definitely behind mythical figures patterns as references, and now setting definite areas.
From ancient mythological narrations to current mappings based on brightness and mathematical calculations of exact locations, many centuries have passed by and many efforts have been made to take notes, transmit and preserve catalogues and representations. This article displays some of those that have remained along the way, not being part anymore of the now recognized 88 constellations. They are 17 constellations introduced in the order they were created, between the XVII and XIX centuries, related to myths and also to objects, animals and famous people in those ages. Cartographies belong to different authors (not necessarily to the constellation's inventor), so the work and year mentioned on each of them refer to the cartographer.

By Ptolemy (150 b.C.). It was the name given to Jason's and crew's ship for starting the epic journey towards the Black Sea in search of the golden fleece to recover the throne of Greece. Goddess Athenea supervised the construction and, when the ship returned to Greek coasts, was devoted to Poseidon. The oak beam in the prow was one of Zeus' oracles, calling to action (it was able to speak, and surrounded by a bank of misdt in Bayer's drawing). One of the greater obstacles to face was the Clashing Rocks, which slid and closed the entrance to the Sea to anything trying to pass through. Argo Navis was the first gallon succeeding and staying safe. After the adventure, the rocks remained apart.
Argo Navis by Johann Bayer (inUranometria, 1603)
By Ptolemy (150 B.C.). He was the Turkish lover of the Roman emperor Adrian in the I c. B.C. An oracle had forecasted the emperor would be saved by sacrificing what he loved the most. Antinous was found drowned in the Nyle river, and later considered as a god with a constellation of his own to the South of Aquila the eagle. Bode depicted him as being grabbed by the claws of the animal, although Ptolemy had specifically mentioned the bird should be looked at from below.
Antinous by Johann Elert Bode (inUranographia, plate IX, 1801)
By Petrus Plancius (XVI c.). It represented Tigris river (Iraq) according to registries made from Madagascar island (approximately at 23° S). It flowed from the neck of the winged horse Pegasus (upper left) and then between Cygnus the swan and Aquila until Ophiuchus the serpent bearer (lower right corner).
Tigris by Jacob Bartsch (inUsus Astronomicus Planisphaerii Stellati, 1624)
By Petrus Plancius (XVI c.). Initially called Apes, it was between Aries the ram and Medusa's head in Perseus (upper part). In the XVII c., Jacob Bartsch called it Vespa and Johannes Hevelius changed it to a fly and called it Musca. During the same century, some of the stars were also part of Lilium, although that figure doesn't exist anymore. Later, it was called Musca Borealis to set a difference from the homologous Southern constellation (the one that still remains).
Musca by Johannes Hevelius (inFirmamentum Sobiescianum, Fig. AA, 1690)
By Edmund Halley (XVII c.). It represented the oak tree inside of which king Charles II of England hid after being defeated by Cromwell in the battle of Worcester. It included stars from Argo Navis's oak although most astronomers didn't recognise it. Later, Boded did include it on his maps although called it Robur Caroli II. It can be appreciated in the right middle area in the image, crossing the ship in a transverse vertical section, with roots in the Southwestern area of Chamaleon and branches extended towards waters.
Robur Carolinum by Johann Elert Bode (inUranographia, plate XX, 1801)
By Johannes Hevelius (XVII c.). It was the mythical three-snake-headed dog at the gates of Hades, the realm of death. One of the 12 challenges Hercules had to face was capturing the dog and taking it to a luminous surface. Previously, Bayer had depicted the heroe holding an apple-tree in his hand although Hevelius changed it to Cerberus. In the following century, John Senex combined both drawings (Ramus Cerberus), whereas John Flamsteed straightly removed them, and his charts included Hercules just grasping thin air. Displayed here is Hevelius's depiction from the space perspective (as on all of his charts).
Cerberus by Johannes Hevelius (inFirmamentum Sobiescianum, Fig. H, 1690)
By Gottfried Kirch (XVII c.). It was created to homage to Frederic III of Brandenburg (Prussia). Made from North-South aligned stars, they composed a ceremony sceptre located at the foot of the hunter Orion, in one of Eridanus river's meanders. The newspaper where it was introduced especially remarked Rigel star in Orion.
Sceptrum Brandenburgicum by Gottfried Kirch (in the newspaperActa Eruditorum of 1688)
By Johannes Hevelius (XVII c.). It included stars from Boötes, the constellation representing the mythical Arcas, son of Callisto and grandson of the king of Arcadia (central Peloponnesus). Maenalus might have been Callisto's brother or son of Arcas. With a mount at the feet of the last character, then he stepped onto his uncle or his own son. The mount was a sacred place to Pan, and Diana's favorite zone (the hunting goddess).
Mons Maenalus by Johannes Hevelius (inFirmamentum Sobiescianum, Fig. F, 1690)
By Pièrre-Charles Le Monnier (XVIII c.). A reindeer represented the course of Halley comet in 1742, between Camelopardalis the giraffe and Cepheus the king (beyond the upper border). An expedition to Lapland had inspired the reindeer figure. In Jamieson's drawing, the tail pointed to the North pole and the head almost touched Custos Messium's arm (a constellation created 32 years later by Lalande). On some maps, it was called Tarandus like the scientific name of the animal (Rangifer tarandus).
Le Réene by Alexander Jamieson (enCelestial Atlas, plate II, 1822)
By Charles Le Monnier (XVIII c.). The astronomer described it as "a bird of India and Philipines", referring to a flightless Asian bird. But his drawing seemed to be a thrush, so during the next century it was called by different names: Turdus solitarius (Bode), Mockingbird (Thomas Young) and, finally, Noctua (Jamieson). Jamieson's depiction was quite different from the first representations: it looks like an owl, similar to those in Egyptian hieroglyphs, showing one side of its body and facing the watcher. The bird was on Hydra's tail, the aquatic serpent, with the head between Libra the scale and the South of Virgo the virgin.
Noctua by Alexander Jamieson (enCelestial Atlas, plate XXVII, 1822)
By Joseph Jérôme de Lalande (XVIII c.). It referred to his countryman, Charles Messier, the comet hunter, shown in the central vertical figure in the image, holding a shepherd stick and pointing with his right hand to Cassiopea's foot, the seated lady. The constellation was located where the comet of 1774 was first seen, between Le Réene the reindeer on the left and Cassiopea. Thomas Young called it The Vineyard Keeper.
Custos Messium by Johann Elert Bode (inUranographia, plate III, 1801)
By Joseph Jérôme de Lalande (XVIII c.). The name was related to the Quarantides, the shower of meteors visible in January. It was located to the North of Boötes, to the South of the body of Draco the dragon and next to the bowed leg of Hercules. Bode changed the name to Latin Quadrans Muralis.
Le Mural by Alexander Jamieson (inCelestial Atlas, plate II, 1822)
By Martin Poczobut (XVIII c.). It made homage to Stanisław August Poniatowski, king of Polony and Lithuania, mentor of arts and sciences, whose coat of arms included a bull. The constellation was located between Aquila and Ophiuchus, overlapping the tail of Serpens. The V-shape of stars in the face of the central bull had been part of the extinct Tigris.
Taurus Poniatovii by Johann Elert Bode (inUranographia, plate IX, 1801)
By Johann Elert Bode (XVIII c.). Invented in 1786, a year after the death of Frederic The Great, king of Prussia, who was remembered as a hero, sage and peacemaker. It was a ceremony sword surrounded by laurel leaves, a feather and a crown in the upper part. It lay next to Andromeda's extended arm, the chained woman, and Cepheus the king (upper right). Bode called it Honour and other names were Honores Friderici and Frederici Honores, although here it is displayed as Jamieson did, as Gloria Frederici.
Honour by Alexander Jamieson (enCelestial Atlas, plate III, 1822)
By Maximilian Hell (XVIII c.). They were two constellations: a telescope (Major) and a reflector (Minor) representing William Herschel's intruments at the time he discovered Uranus in 1781. The constellations were located where the planet had been discovered: the reflector was between Orion and the head of Taurus the bull, and the telescope was just above the arrow held by Castor in Gemini. Later, Bode gathered them in a single constellation, called it Telescopium Herschelii and placed it where the telescope (although drawn with the reflector's dimensions).
Tubus Herschelli by Maximilian Hell (in Monumenta, Aere Perenniora, Inter Astra Ponenda, 1789)
By Johann Elert Bode (XIX c.). To homage the invention of the Montgolfier brothers that had reached the skies to the South of Capricorn the goat-fish in 1780's decade. On the chart, the globe rises up with an empty basket, between the left foot of Aquarius the water-bearer and Capricorn, with Piscis Notius' tail on the left and Microscopium on the right. The constellation was introduced by Bode although Lalande suggested so.
Globus Aerostaticus by Johann Elert Bode (inUranographia, plate XVI, 1801)
By Johann Elert Bode (XIX c.). Again, another suggestion coming from Lalande and displayed on a chart by Bode, this time to make homage to another invention too: Gütenberg's printing press created 350 years before. It was located just below the legs of Monoceros the unicorn, to the North of Argo Navis' prow and to the West of Canis Major the greater dog.

The Arabian astronomer Ἁbd al-Raḥmān al-Ṣūfī (903–986) added over 40 stars to Ptolemy's Almagest from the observatory of the Persian city of Shīrāz (29.6°N, Iran). His book Kitāb Ṣuwar al-kawākib (al-thābitah) also updated the locations mentioned by the Greek one although without taking new notes but calculating based on the precession of equinoxes. He drew each constellation twice, with no coordinates, from both terrestrial and space perspectives.

PhD. Filosophy thesis by Adèle Lorraine Wörz (2006) in Oregon University, entitled "The visualization of perspective systems and iconology in Dürer’s cartographic works: an in-depth analysis using multiple methodological approaches". It describes different methodologies for a critical appreciation of the history of cartography as well as the arts history. Next, it reviews Dürer's works by looking for meanings, conditionings and different kinds of subjective expressions at the time of considering spatial relations, perspectives, projections and iconology in his artworks.
