Caesar's Comet
Caesar's Comet (also ''Sidus Iulium'' ("Julian Star"); ''Caesaris astrum'' ("Star of Caesar"); Comet Caesar; the Great Comet of 44 BC; numerical designation C/−43 K1) was a seven-day cometary outburst seen in July 44 BC. It was interpreted by Romans as a sign of the deification of recently assassinated dictator, Julius Caesar (100–44 BC). Based on two questionable reports—one from China (May 30) and another from Rome (July 23)—an infinite number of orbit determinations can fit the observations, but a retrograde orbit is inferred based on available notes. The comet approached Earth both inbound in mid-May and outbound in early August. It came to perihelion (closest approach to the Sun) on May 25, −43 at a solar distance of about . At perihelion the comet had a solar elongation of 11 degrees and is hypothesized to have had an apparent magnitude of around −3 as the Chinese report is not consistent with daytime visibility during May.See Ramsepp. 122–23:(Comet abso ...

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech.

Recorded History
Recorded history or written history describes the historical events that have been recorded in a written form or other documented communication which are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BCE, and it coincides with the invention of writing. For some geographic regions or cultures, written history is limited to a relatively recent period in human history because of the limited use of written records. Moreover, human cultures do not always record all of the information which is considered relevant by later historians, such as the full impact of natural disasters or the names of individuals. Recorded history for particular types of information is therefore limited based on the types of records kept. Because of this, recorded history in different contexts may refer to different periods of time depending on the topic. The interpr ...

Naturalis Historia
The ''Natural History'' () is a Latin work by Pliny the Elder. The largest single work to have survived from the Roman Empire to the modern day, the ''Natural History'' compiles information gleaned from other ancient authors. Despite the work's title, its subject area is not limited to what is today understood by natural history; Pliny himself defines his scope as "the natural world, or life". It is encyclopedic in scope, but its structure is not like that of a modern encyclopedia. It is the only work by Pliny to have survived, and the last that he published. He published the first 10 books in AD 77, but had not made a final revision of the remainder at the time of Pliny the Elder#Death, his death during the Eruption of Mount Vesuvius in 79 AD, AD 79 eruption of Vesuvius. The rest was published posthumously by Pliny's nephew, Pliny the Younger. The work is divided into 37 books, organised into 10 volumes. These cover topics including astronomy, mathematics, geography, ethn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is Lost literary work, no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius.

Suetonius
Gaius Suetonius Tranquillus (), commonly referred to as Suetonius ( ; – after AD 122), was a Roman historian who wrote during the early Imperial era of the Roman Empire. His most important surviving work is ''De vita Caesarum'', commonly known in English as '' The Twelve Caesars'', a set of biographies of 12 successive Roman rulers from Julius Caesar to Domitian.

A few of these books have partially survived, but many have been lost.

Assassination Of Julius Caesar
Julius Caesar, the Roman dictator, was assassinated on the Ides of March (15 March) 44 BC by a group of senators during a Roman Senate, Senate session at the Curia of Pompey, located within the Theatre of Pompey in Ancient Rome, Rome. The conspirators, numbering between 60 and 70 individuals and led by Marcus Junius Brutus, Gaius Cassius Longinus, and Decimus Junius Brutus Albinus, stabbed Caesar approximately 23 times. They justified the act as a preemptive defense of the Roman Republic, asserting that Caesar's accumulation of lifelong political authority—including his perpetual dictatorship and other honors—threatened republican traditions. The assassination failed to achieve its immediate objective of restoring the Republic's institutions. Instead, it precipitated Caesar's posthumous Roman imperial cult, deification, triggered the Liberators' civil war (43–42 BC) between his supporters and the conspirators, and contributed to the collapse of the Republic.

Edmund Halley
Edmond (or Edmund) Halley (; – ) was an English astronomer, mathematician and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720. From an observatory he constructed on Saint Helena in 1676–77, Halley catalogued the southern celestial hemisphere and recorded a transit of Mercury across the Sun. He realised that a similar transit of Venus could be used to determine the distances between Earth, Venus, and the Sun. Upon his return to England, he was made a fellow of the Royal Society, and with the help of King Charles II, was granted a master's degree from Oxford. Halley encouraged and helped fund the publication of Isaac Newton's influential ''Philosophiæ Naturalis Principia Mathematica'' (1687). From observations Halley made in September 1682, he used Newton's law of universal gravitation to compute the periodicity of Halley's Comet in his 1705 ''Synopsis of the Astronomy of Comets''. It was named after him upon its predicted ret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ludi Victoriae Caesaris
''Ludi'' (Latin:games; plural of "ludus") were public games held for the benefit and entertainment of the Roman people (''populus Romanus''). ''Ludi'' were held in conjunction with, or sometimes as the major feature of, Roman religious festivals, and were also presented as part of the cult of state. The earliest ''ludi'' were horse races in the circus (''ludi circenses''). Animal exhibitions with mock hunts (''venationes'') and theatrical performances (''ludi scaenici'') also became part of the festivals. Because some of these entertainments are not competitive "games", ''ludi'' may also be translated more generally as "shows". Days on which ''ludi'' were held were public holidays, and no business could be conducted—"remarkably," it has been noted, "considering that in the Imperial era more than 135 days might be spent at these entertainments" during the year. Although their entertainment value may have overshadowed religious sentiment at any given moment, even in late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
