Claudius Ptolemy is a famous ancient scholar.Ptolemy is famous for his works and specialization in astronomy, geography, cartography, mathematics, and astrology. His works range from the Almagest, a series of thirteen books dedicated to astronomy. The use of mathematics to was used to prove his theories and observations of an Earth-centered universe. His works on astronomy, such as the Geocentric model, are well renowned for their Earth-centered theories. Ptolemy’s theories and works lasted for thousands of years until astronomers such as Galileo, Copernicus, and Kepler came into the picture to test their theories against the longstanding theory of Ptolemy’s geocentric model. Not only was Ptolemy famous for his works on astronomy and the Almagest but the famous Greek was also fond of astrology from a scientific view point. Astrology was an important study back in ancient Greece and Ptolemy’s skills did not leave that off of his knowledge. He published one of the most famous books in astrology named the Tetrabiblos. The addition of the Geographia by Ptolemy himself allowed the Greeks to excel their understanding of their environments geography.
Claudius Ptolemy was born in Alexandria, Egypt around 90 AD. Some information differs on the originality of the name Ptolemy. For example, the name Ptolemy was a common name in ancient Greece. “Claudius” came from the first Roman rule of Egypt as a common name. Following the lost of Roman rule, Ptolemy I Soter, a Macedonian general of Alexander the Great became Egypt’s ruler.
The general idea of planets and their motion in Ptolemy’s era was that the planets and heavens are all perfect. Although the Greeks knew that the Earth was round from observing lunar eclipses, their accepted theory was that the Earth was at the center of the universe with all of the planets moving around it in a perfect orbit; in addition, Greeks…...

She had several brothers and sisters, including Ptolemy XII and Ptolemy XIV, both of which she married as per the traditional Egyptian custom, and Cleopatra VI Tryphaena, who attempted to poison her younger sister, Cleopatra VII. Prior to Cleopatra’s mother and father departing to Rome, Cleopatra VI took over the throne, but died shortly afterwards, leaving the title of pharaoh to the young eighteen year-old Cleopatra and ten year-old Ptolemy. Although Ptolemy and she were a joint heir, Cleopatra made it clear that she did not intend on sharing the power with him. Ptolemy soon become conscious of Cleopatra’s intent and banished his wife and sister from Egypt. In attempt to gain alliance with Rome, thirteen year-old Ptolemy XII beheaded who he believed to be an enemy of Julius Caesar, but his assumptions were brutally incorrect. To punish Ptolemy, Caesar took over the Egyptian capital and declared himself arbitrator between Ptolemy and Cleopatra’s rivaling feud. Cleopatra decided to take advantage of Caesar’s resentment towards Ptolemy, and had discreetly snuck her way into the palace to meet with Caesar. She shortly afterwards became his mistress, and in 47 BC gave birth to Ptolemy Caesar, nicknamed Caesarion. Ptolemy XII’s army was eventually conquered by Julius Caesar’s, and Cleopatra was given back her title as Queen of Egypt, ruling alongside her younger brother, Ptolemy XIV.......

History 1

...level among the Hellenes, but it was not until the second century CE that it reached its zenith. This came with Ptolemy, Claudius Ptolemaeus (the cognomen may have been given him because he was born in Ptolemais, in Upper Egypt). Ptolemy lived from ca. 85 to ca. 165 CE and spent his adult life at Alexandria. He was an indefatigable scholar, and in addition to his astronomical work he wrote a comprehensive Geography, two works on optics and the refraction of light, a chronography and several other treatises. Ptolemy’s magnum opus was his massive Mathematikē syntaxis (Mathematical Composition). In the first part of this thirteen-book study he mapped the skies, using triangulation or trigonometric calculations to establish the location of more than a thousand stars in all the visible constellations. These stars, he supposed, were fixed on a sphere that daily rotated around the earth. Then Ptolemy calculated the seven spheres in which moved the sun, moon and five planets. The observations on which the system was based were made from the latitude of Alexandria and Canopus between 121 and 147 CE. The earth, round and stationary, was in the center of Ptolemy’s world. Above the earth in ascending spheres orbited the planets, the moon, the sun, and last of all the sphere of the fixed stars, which by its rotation drew the lesser celestial bodies with it. In his later years Ptolemy wrote brief summaries of his astronomical system, and both the longer and shorter works found many......

Essay on Claudius

...Shakespeare in the 1600’s invites us into the minds of many ruthless characters. Claudius was appointed king after his brothers’ suffering death followed by his marriage to the queen. Claudius plays a confident king to the eye of Denmark,; yet inside he is unstable and hides an unforgiving secret that he himself killed the king. His erratic behavior begins to worry him about his choices and eventually leads him into destroying his relationships with the people closest to him. This essay will investigate the process Claudius went through as he descends from his aspiration to be king, to guilt, to finally, self-defeat. Claudius made a courageous speech to the court about his sorrows towards the kings’ death. However, he was just trying to cover up how he betrayed his own brother. Claudius shows confidence and leadership in his speech, he started with saying “Though yet of Hamlet our dear brother’s death/The memory be green, and that it us befitted/To bear our hearts in grief and our whole kingdom/To be contracted in one brow of woe” (1. 2, 1-4). This shows the reader that Claudius is taking charge of the situation and telling the people of the court to stay strong and move on; displaying his ambition to be king. As declared by Nicholas J. Bonnet, “This speech seems carefully planned out, as if Claudius had written it out before he delivered it” in his article on Student Pulse, displays that Claudius is passionate about his station. This declares he has been waiting for this......

Intertestamental Period

...Greek and Oriental cultures. In 3 323 Alexander became ill and caught a fever and eventually succumbed to it. Alexander’s conquests had a major impacts on Europe and Asia. (Borza 438-439). After his death four of his generals decided to divide Alexander’s kingdom amongst them. During this time Hellenistic culture continued to grow and thrive in Ptolemaic, Seleucid and Roman cultures. Ptolemy was one of Alexander’s generals and he claimed Egypt so as to avoid conflict with any of the other three generals. During the reign of Ptolemy Philadelphus between 285–246 B.C. the entirety of the Old Testament was translated into Greek and became known as the Septuagint, many Jews were becoming fluent in Greek at this time as opposed to their native language of Hebrew. Also writers of the New Testament quite often referred to the Septuagint when quoting the Old Testament. Palestine once again changed rulers when Ptolemy V was defeated in battle by the Syrians. This occurred in 198 B.C. and thus began the Syrian period over a nation that had been divided by war. Half the nation gave support to Ptolemies of Egypt and the other half to Syria and because of this power struggles between the two sides occurred for many years. Palestine had been taken over by a man named Antiochus and many deemed him “Epimanes” meaning “mad man.” Antiochus cared little about Hellenistic religion but wanted to bring the kingdom together on a religious basis. He also sought to control any offerings that......

Geography Topics

...Question# 1 The geocentric view of the universe was long since developed in ancient Greece by an astronomer named Claudius Ptolemy (AD 90- 168). Ptolemy believed that the sun, stars and other planets revolved around the earth. The idea of “Geocentric” means everything revolves around Earth. It wasn’t long until Nicolaus Copernicus (1473-1543), an astronomer from Poland came up with a new theory that the solar system actually revolved around the sun. He invented the idea of a solar system. Revolutions (1543) was Copernicus’ final work explaining the heliocentric view of the universe. “The trouble was that nothing he could say or do made people feel they were living on a moving, spinning planet” (Gingerich & MacLachlan, 2005, p. 111) The four major contributors to the development of modern astronomy after Copernicus were Johannes Keppler, Galileo Galilei, Isaac Newton and Albert Einstein. Keppler defended the Copernican system in developing the three laws of planetary motion. Kepler’s First, Second and Third Laws are 1. The orbit of every planet is an ellipse with the sun at a focus. 2. A line joining a planet and the sun sweeps out equal areas during equal intervals of time. 3. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. ("Johannes Kepler Facts, Quotes, Laws of Planetary Motion, Astronomy, Information", n.d., p. 1) Galileo in some cases is given credit to creating the telescope but......

Solar System

...Solar System Our understanding of the Solar System has changed over time. For over one thousand years the widespread belief was that the earth was stationary and at the center of the universe. Since that time, through a series of discoveries it has been proved that the earth not stationary and it is not at the center of the universe. The Ptolemaic system was developed early in the first century by Claudius Ptolemy who believed like most Greek Scholars in the geocentric view that the earth was stationary and at the center of the universe. Over one thousand years later, Nicolas Copernicus, a mathematician and astronomer believed in the heliocentric theory that it was not the earth, but the sun that was the center of the universe. His book, “On the Revolution of the Heavenly Spheres” laid the groundwork for future observations and discoveries and his work became known as the Copernican model. Galileo’s observations through the use of a telescope he built, was able to provide the evidence needed to support the heliocentric theory. In 1572 Tyler Brahe discovered a new star and after sixteen months it disappeared from site. This discovery conflicted with earlier views that the stars were fixed. (Space Discovery website, n.d.) Based on his observations and measurements of our solar system, Brahe proposed a model that fell in between the Ptolemaic and Copernican models. (The Obervations of Tycho Brahe, n.d.) His discoveries and writings were central to the advancement in...

Claudius Soliloquy Analysis

...Arturo Kuang B block 11/12/14 Claudius soliloquy analysis In Act III, scene III, Shakespeare illustrates Claudius's inner turmoil with an internal monologue. In Claudius's soliloquy, he states that he had murdered his brother,the absolute confirmation that such an act has occurred. Through Claudius soliloquy, Shakespeare reveals Claudius's inner character and further characterizes his disposition, though the remorse he feels is not for his slain brother but for the consequences he faces because of it. Shakespeare is able to depict Claudius’s internal conflict and how it reflects his character. In Claudius’s confession, Shakespeare is able to expose a sharp alteration to his character; he goes from being a fraud to a caring, sensitive, and emotional human being. WIth the first line in his soliloquy, Claudius’s grieves over the fact he has murdered his brother--the king: “O, my offence is rank, it smells to heaven”(3.3 40). With the use of hyperbole, Claudius’s is able to emphasize his sin is so foul that it can even be smelled from “heaven”. The “rank” he has stolen as king is an “offense”, which also emphasizes Claudius’s regret over killing the king. This is unusual for Claudius’s as he is suppose hide under the facade of a person who has killed the king--a insensitive character who only cares for power. Claudius’s feels cursed by his atrocity, that God has struck him: “It hath the primal eldest curse upon’t”(3.3 41). With this allusion to the Biblical......

Evidence points to the first compound microscope appearing in the Netherlands in the late 1500s, probably an invention of eyeglassmakers there:[1] Hans Lippershey (who developed an early telescope) and Zacharias Janssen (also claimed as the inventor of the telescope). There are other claims that the microscope and the telescope were invented by Roger Bacon in the 1200s,[2] but this is not substantiated. Giovanni Faber coined the name microscope forGalileo Galilei's compound microscope in 1625 [3] (Galileo had called it the "occhiolino" or "little eye"). 2nd Century BC - Claudius Ptolemy described a stick appearing to bend in a pool of water, and accurately recorded the angles to within half a degree. 1st Century - Romans were experimenting with glass and found objects appeared larger when viewed through this new material. 1590 - Two Dutch spectacle makers, Zacharias Jansen and his father Hans started experimenting by mounting two lenses in a tube, the first compound microscope. 12th Century - Salvino D'Armate from Italy made the first eye glass, providing the wearer with an element of magnification to one eye. 1609 - Galileo Galilei develops a compound microscope with a convex and a concave lens 1665 - Robert Hooke's book called Micrographia officially documented a wide range of observations through......

Paradigm Shift

...look at a paradigm shift is through example, using example of Ptolemy, whose fixation upon a paradigm created problems. Ptolemy, in common with most Ancient Greek philosophers, believed that the earth was at the center of the universe, and that the sun and other planets revolved around it. The problem with that view came when Ptolemy, and later observers, made more accurate observations. More epicycles had to be added, making circles within circles. It was not until Copernicus that this view was challenged. He postulated that the sun was at the center of the solar system, which was regarded as the center of the universe at that time. The paradigm shifted, and it was only the resistance of the church that prevented immediate adoption. After this came Newton’s ideas and physics worked within a new paradigm. Ptolemy is often used as a metaphor for bad science and irrationality, but this is very unfair, and is an example of a fallacy, an argument from superiority. Using the equipment he had available, with no telescopes and limited mathematics, there was little wrong with his theory or methods. His measurements were supremely accurate and were used for measuring the motion of the planets until the time of Copernicus. His rigorous and meticulous approach was faultless, and he was a good empirical scientist. Copernicus, Galileo and Newton had a lot of respect for him, so the modern world must be careful not to judge Ptolemy harshly. Unfortunately, this is one of the downsides of......

...Aristotle saw as unique to human beings. 01-Ellis-45685:01-Ellis-45685 7/16/2008 7:00 PM Page 4 4— P E R S O N A L I T Y T H E O R I E S Descartes René Descartes (1596–1650), a French philosopher, viewed human personality as the product of the interaction of divine and primal forces. He saw the essential force behind human personality as the immortal soul—pure, perfect, and intangible. Descartes set out to explain how this spiritual entity interacted with the physical body. His observation of an anatomical dissection led him to think he had resolved this mind-body problem. He noticed a small body in the apparent center of the brain known as the pineal gland or pineal body, so named by the Greco-Roman physician Claudius Galen (c. 130–c. 200 CE) because its shape reminded him of a pine cone. Descartes (1649) came to the conclusion that that this cone-shaped endocrine gland must be the point of contact between the soul and the body. Cartesian dualism, which is the philosophical position that two substances—matter and spirit, or brain and mind—exist independently of each other although they interact—became the most common view in the Christian West after the seventeenth century because it “explained” the existence of human free will and consciousness in an otherwise mechanistic universe. Indeed, before the advent of the computer, it seemed impossible to allow for consciousness without appealing to nonphysical concepts. Cartesian dualism is still...

...The Terrestrial Realm consisted of all material objects. All material objects, or matter, were made of combinations of the four elements (earth, air, fire, and water). Matter was classified by common physical properties (density, hot vs. cold, wet vs. dry). Comets were thought to be atmospheric phenomena, and part of the Terrestrial Realm (changes in the tail of a comet can be observed). The Celestial Realm consisted of everything in the heavens – stars, planets, etc. – and the fifth element, the “luminiferous aether.” The fifth element, according to Aristotle, was a transparent, solid but flowing, mysterious substance responsible for holding up the objects in the Celestial Realm and keeping them rotating around a central earth. Claudius Ptolemy (90 C.E. – 160 C.E.) – Greco-Roman writer, mathematician, astronomer, philosopher, and astrologer from Alexandria (modern day Egypt, but once part of the Roman Empire). He wrote the Almagest, the great treatise on astronomy (from which European and Islamic astronomy was built.) He explains the seven planets (in order; Sun, Mercury, Venus, Moon, Mars, Jupiter, and Saturn) as orbiting the earth in perfect circular paths. This “Geocentric Model of the Universe” agreed with Roman Catholic thought. He explained “retrograde motion” (apparent backwards motion of Mars, Mercury and Venus) using a complicated system of “epicycles.” Problems – Geocentric model was too complicated, and failed to make accurate predictions.

Astronomy Then and Now

...time their long gone. Of course, I am speaking about Ptolemy, Copernicus, and Kepler. Funny thing is each one of them challenged and changed their predecessor's work, for the better of course, but we will get to that later. We have these three men to thank for a whole lot of new tricks. To name a few would be, our solar system, the way we form our maps, and we can’t forget the numerous mathematical formulas used to make ideas come to life. In this research paper, we will touch base on the lives of three great astronomers and the tricks they have taught us. We will also see how astronomers of today contribute to our everyday lives. Some say that our first astronomer was a great astronomer. Other say, “Ptolemy was the only great astronomer of Roman Alexandria.” (Brown, 2016) It’s all a matter of opinion, but what we cannot deny was Ptolemy was a great astronomer of his time and today. We do not know much about Ptolemy’s personal life. What we do know about him came from his work. He was born around 85ce in Egypt to a Greek family even though he bore a roman name. To say Ptolemy was diverse is an understatement. He was also diverse in his studies being he was a mathematician, geographer, and astrologer. We know he was a Roman citizen, due to his name, which was most likely given to an ancestor and carried down. We know his family must have been Greek because he wrote in Greek even though he lived in Egypt. Ptolemy was a great mathematician, astronomer and known......

Odyessey of exiled Cassius Severus. Not a great speaker. By continuing his practices of aggressiveness he was deprived of property, outlawed and ended his days on the rock of Seriphos. About this time, praetor Plautius Silvanus threw his wife Apronia out of a window. He claimed he was asleep and knew nothing and that wife must have killed herself. Tiberius instantly inspected the bedroom—signs of violence and resistance were detectable an so went to trial. Silvanus was sent a dagger by grandmother Urgulania. Then he had his veins opened and soon afterwards his first wife Numantina was acquitted of driving her husband insane. This year finally freed Rome from long war with Numidian Tacfarinas. He continued to ravage Africa and their king Ptolemy was too young for responsibility. Governor of Africa was Publius Cornelius Dolabella. He collected all troops and managed to raise siege at first onset. When Numidians stationed themselves, Dolabella dispatched quick moving infantry and were dragged to death as they had no weapons—Romans tired of hardships and took bloody vengeance. Dolabella’s request for an honorary Triumph was rejected by Tiberius out of consideration for Sejanus—to avoid lessening glory of the latter’s uncle, former governor Quintus Junius Blaesus. This did not help the reputation of Blaesus but rebuff increased that of Dolabella, who had to his credit important prisoners, enemy commander’s death, and termination of war. In the same summer, a slave war in......
