Timeline of planetariums
From Wikipedia, the free encyclopedia
This is a timeline of the history of planetariums.
| 1473 BCE | Egyptian tomb of Senenmut features the earliest known depiction of the sky. |
| 500 BCE | "The Dome of Heaven", built by the Etruscans, is the oldest known domed building. |
| 428/427–348/347 BCE | Greek philosopher Plato discusses his Allegory of the Cave, which analogizes human perceptions of reality with the shadows created by projections of objects against the wall of a cave that is lit by firelight. It is these projected shadows of objects (and not the objects themselves) that become the most important sources of information about the world for most people. |
| 370 BCE | The original sculpture copied by the later Farnese Atlas, which itself features what is probably the oldest preserved rendering of a globe-like object (though it depicts the celestial sphere rather than the Earth), is created in Hellenistic Greece. The Farnese Atlas, a Roman copy which dates to AD 150, is the oldest surviving pictorial record of Western constellations and is now at the National Archaeological Museum in Naples, Italy. The position of the constellations on the sphere's equinox have been used to date the design of the original Greek sphere to 370 BCE. Two other celestial globes believed to date from classical times are the Kugel globe and the Mainz globe. |
| 250 BCE | Archimedes is the first to demonstrate a cast-metal globe showing the motions of the planets. After he was killed by invading Romans, the device was taken to Rome, where it was described by Cicero. Later, Ptolemy's globe is alleged to have even demonstrated the precession of the equinoxes. |
| 50 BCE | The Hathor temple at Dendera dates from Ptolemaic times, probably the 1st century BCE. The temple contains two well-known but slightly different representations of the heavens. There is a round zodiac ceiling and a square zodiac in the outer hypostyle hall. The round zodiac ceiling shows the whole sky as it was understood by both Greek and Egyptian cultures. |
| 62 CE | The Golden House of Nero includes a dome rotating with the sky. |
| 124 CE | The Roman Pantheon is constructed in Rome. |
| 150 CE | Ptolemy's designs for a Celestial Globe are recorded. No actual globe has been found, but detailed notes on its construction have. |
| 531 CE | "Palace of Chosros" at Ctesiphon, near modern Baghdad, Iraq, whose massive 85-foot-high brick arch was said to be painted with stars against a blue background, indicating the zodiac. |
| 840 CE | Abbas Ibn Firnas constructed a device which indicated the movement of the planets and stars in the Universe |
| 1229 | Frederick II, Holy Roman Emperor brings to Italy a tent captured during the Fifth Crusade. Now lost, the tent had a cupola-shaped roof with a clockwork mechanism showing moving constellations.[1] |
| 1584 | Celestial Globe of Tycho Brahe. Covered with brass and having a wood interior measuring six feet in diameter, with the outer surface divided by circles to show degrees and minutes and stars visible with the naked eye, it was destroyed by fire in 1728. A disadvantage to earlier globes was that they showed the sky in reverse, such that the observer could only view the stars as seen outside the planetsphere. |
| 1654 | The Globe of Gottorf is constructed in St. Petersburg. It was about four meters in diameter, weighed over three tons, and could seat several persons inside on a circular bench. The stars were holes in the surface of the globe. The original was destroyed by fire and almost entirely rebuilt in 1748–52. |
| 18th century | Navajo 'Star Ceilings' painted by hand and with 'paint arrows' on overhanging cliff faces in Canyon De Chelly, in modern-day Arizona, United States. |
| 1774 | Construction begins on Eise Eisinga's planetarium (actually an orrery) in Franeker, province of Friesland, The Netherlands. Today it is the oldest working planetarium in the world. It was built between 1774 and 1781. |
| 1846 | The Carl Zeiss Company is founded. Zeiss produced microscopes in his home workshop. Later collaboration with Ernst Abbe resulted in the first optical instruments produced from theory and plans, rather than from trial and error. Later still, Otto Schott, a glassmaker, introduced a process for producing good quality optical glass reliably, and the company established its reputation as a maker of high-quality optical goods. |
| 1912 | The orbitoscope is invented by E. Hindermann in Basel, Switzerland. This instrument is driven by springworks and has two planets revolving about a central Sun. A small light bulb on one of the planets projects shadows of the other two objects in the directions they would be seen from that planet, reproducing accurately the retrograde loops and speed changes. This ingenious device is useful for instruction, but of course had many shortcomings. |
| 1913 | The Atwood Globe is built in the Museum of the Chicago Academy of Sciences. With a diameter of almost five meters, the Atwood Globe shows 692 stars, and a moveable light bulb represents the Sun. Apertures along the ecliptic, which can be uncovered as necessary, represent the planets. |
| The idea of realistically reproducing the sky in detail is attributed to astronomer (and then privy counselor) Max Wolf. He was involved with the Deutsches Museum. Wolf had suggested to von Miller the idea of a device for his museum which would reproduce not only the stars but also the planetary motions. Von Miller approached the well-known optical firm of Carl Zeiss in Jena, and they agreed to look into the problem. |
