Farnese Atlas

Summary
The Farnese Atlas is a 2nd-century AD Roman marble sculpture of Atlas holding up a celestial globe. Probably a copy of an earlier work of the Hellenistic period, it is the oldest extant statue of Atlas, a Titan of Greek mythology who is represented in earlier Greek vase painting, and the oldest known representation of the celestial spheres and the classical constellations. The sculpture is at the National Archaeological Museum of Naples, in Italy. The statue is dated around AD 150, during the Roman Empire and after the composition of the Almagest by Claudius Ptolemy, but the celestial globe has long been presumed to represent constellations mapped in earlier Hellenistic astrology, particularly in the work of Hipparchus in the 2nd century BC. Atlas labors under the weight because he had been sentenced by Zeus to hold up the sky. The sphere shows a depiction of the night sky as seen from outside the outermost celestial sphere, with low reliefs depicting 41 (some sources say 42) of the 48 classical Greek constellations distinguished by Ptolemy, including Aries the ram, Cygnus the swan and Hercules the hero. The sculpture stands tall, and the sphere is in diameter. The name Farnese Atlas reflects its acquisition by Cardinal Alessandro Farnese in 1562, and its subsequent exhibition in the Villa Farnese. In 2005, at a meeting of the American Astronomical Society in San Diego, California, Bradley E. Schaefer, a professor of physics at Louisiana State University, presented a widely reported analysis concluding that the text of Hipparchus' long lost star catalog may have been the inspiration for the representation of the constellations on the globe, thereby reviving and expanding an earlier proposal by Georg Thiele (1898). The constellations are fairly detailed and Schaefer regards them as scientifically accurate given the period of the globe's creation, implying that it was modeled after a scholarly work.

Star chart
A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. They have been used for human navigation since time immemorial. Note that a star chart differs from an astronomical catalog, which is a listing or tabulation of astronomical objects for a particular purpose. Tools utilizing a star chart include the astrolabe and planisphere.
Star catalogue
A star catalogue is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient people, including the Babylonians, Greeks, Chinese, Persians, and Arabs. They were sometimes accompanied by a star chart for illustration.
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The origins of the earliest constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, or mythology. Different cultures and countries invented their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized.
