Oxford University Press (Clarendon Press), 1997 (reprint of 1913 edition). Cloth, dj. Our Price: $24.00 Book Number 17620 Sir Thomas Heath (1861-1940) was a leading authority on ancient mathematics, renowned for individual works on Apollonius of Perga, Archimedes and Euclid, and for his histories of Greek mathematics and astronomy. In this book he presents the Greek text of Aristarchus'treatise "On the sizes and distances of the Sun and Moon", with English translation, notes and commentary. Aristarchus (c.310-230 BC) is credited, on the authority of Archimedes, with the heliocentric hypothesis: he was in fact the originator of the Copernican hypothesis. To substantiate this claim, Heath traces every step in the progress towards Aristarchus'hypothesis, presenting a complete history of Greek astronomy up to Aristarchus before going on to the critical edition of his treatise. back to list of reprints > back to home page >

Site Map (9a) May Earth be Revolving around the Sun? Aristarchus of Samos, an early Greek astronomer (about 310 to 230 BC), was the first to suggest that the Earth revolved around the Sun, rather than the other way around. He gave the first estimate of the distance of the Moon ( section (8c) precession of the equinoxes Except for one calculationan estimate of the distance and size of the Sunno work of Aristarchus has survived. However, one could guess why he believed that the Sun, not the Earth, was the central body around which the other one revolved. His calculation suggested that the Sun was much bigger than the Eartha watermelon, compared to a peachand it seemed unlikely that the larger body would orbit one so much smaller. Here we will develop a line of reasoning somewhat like the one Aristarchus used (for his actual calculation, see reference at the end). Aristarchus started from an observation of a lunar eclipse section (8c) twice as wide as the Moon. Suppose the width of the shadow was also the width of the Earth (actually it is lesssee below). Then the diameter of the Moon would be Aristarchus next tried to observe exactly when half the moon was sunlit . For this to happen, the angle Earth-Moon-Sun (angle EMS in the drawing here) must be

Branch of Science Astronomers Branch of Science Philosophers ... Greek Aristarchus of Samos (ca. 310-ca. 230 BC) Greek philosopher who theorized the radical view that Earth and planets revolve around the Sun This model was too revolutionary to be accepted by his contemporaries who debunked the theory because it conflicted with geocentric religious principles, as well as Aristotle's principle that all objects move toward the center of the Earth Aristarchus' model also predicted stellar parallax and seemed to imply that falling bodies would be swept westward, neither of which were observed. Aristarchus explained the lack of observed parallax by postulating that the stars were infinitely far away. Aristarchus also applied modern geometric methods to measuring the size of celestial bodies. From a lunar eclipse he concluded that the radius of the Moon was 0.5 times the radius of the Earth (actually 0.28 times). He measured the Moon's Earth Moon distance to be 114.6 Earth radii (actually 60.4). By noticing that the Sun and Moon have equal angular diameters during a solar eclipse he calculated that the distance to the Sun was 19.1 times the distance to the

This page last modified 1998 July 16 Ancient Greek Astronomy Making Sense of the Heavens In our understanding of the heavens, we owe a great deal to those who have gone in the centuries before us. Stars and Planets When our ancestors looked at the sky, they saw a dome upon which lights moved. Some of these lights, the stars, remained in the same position in relation to each other. The stars can be divided into two groups: those which rise and set and those which remain above the horizon whilst they appear to circle a fixed point in the sky, the celestial pole. Our ancestors noticed that this fixed point was higher in the sky rose higher if they travelled northwards, and vice versa. This was seen as evidence that the surface of the Earth is curved. The positions of others, including the brightest ones, changed. These were called "wanderers" (in Greek: "planetos") They were often identified with deities. The seven naked-eye wanderers, or planets, were, in order of speed of apparent movement: Moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn. The planets' movements are confined to a narrow band of stars a few degrees either side of the path of the Sun, the ecliptic, so called because eclipses can occur when the Moon is on the ecliptic. The constellations of the ecliptic were granted special status as the Zodiac. There are 12, one for each lunation during the course of a year.

Aristarchus Scientists Home Page Anaxagoras Archimedes Eratosthenes ... Pythagoras Aristarchus of Samos (310-230 B.C.), was a astronomer often referred to as the Copernicus of antiquity, laid the foundation for much scientific examination of the heavens. According to his contemporary, Archimedes, Aristarchus was the first to propose not only a heliocentric universe, but one larger than any of the geocentric universes proposed by his predecessors. Copernicus himself originally gave credit to Aristarchus in his own heliocentric treatise, De revolutionibus caelestibus , where he had written, "Philolaus believed in the mobility of the earth, and some even say that Aristarchus of Samos was of that opinion." Interestingly, this passage was crossed out shortly before publication, maybe because Copernicus decided his treatise would stand on its own merit. Plutarch in his De facie in orbe lunae gives reference not only to Aristarchus's theory, but to the way it was received by contemporaries. The general opinion of the time appeared to be that of Dercyllides, who "says that we must suppose the earth, the Hearth of the House of the Gods according to Plato, to remain fixed, and the planets with the whole embracing heaven to move, and rejects with abhorrence the view of those who have brought to rest the things which move and set in motion the things which by their nature and position are unmoved, such a supposition being contrary to the hypotheses of mathematics." As we can imagine, this did not look good for Aristarchus, and was probably one of the main reasons the heliocentric hypothesis did not re-emerge until the mid 15th century with the Copernican revolution.

Archimedes and sandcorn counting Archimedes was killed while drawing circles on the ground . Let us supposed it was sand. Reading about Aristarchus heliocentric world he was thinking how many sand grains are required to fill the entire then known universe. There are some, King Gelon, who think that the number of the sand is infinite in multitude; and I mean by the sand not only that which exists about Syracuse and the rest of Sicily but also that which is found in every region whether inhabited or uninhabited. Archimedes He knew that Aristarchus of Samos in his model expanded the size of the universe. Aristarchus of Samos has set forth writings of certain hypotheses, in which from the things that are established it follows that the universe is many times greater than that now told. For it is proposed that the fixed [ones] of the stars and the sun remain motionless, and that the earth is borne around the sun along the circumference of a circle, [the sun] remaining in the middle of the course, and the sphere of the fixed stars lying around the same center as the sun being of so great a magnitude, that the circle, along which the earth is presumed to be borne, has such a proportion to the distance of the fixed [ones], as the center of the sphere has to the surface... Archimedes THE SAND RECKONER For a finite world there cannot be infinite number of sand grains. But what is the maximum number required to fill the entire universe?

Greek Astronomy Facts Herodotus, the Father of History, tells us that once upon a timewhich time, as the modern computator shows us, was about the year 590 B.C. a war had risen between the Lydians and the Medes and continued five years. "In these years the Medes often discomfited the Lydians and the Lydians often discomfited the Medes (and among other things they fought a battle by night); and yet they still carried on the war with equally balanced fortitude. In the sixth year a battle took place in which it happened, when the fight had begun, that suddenly the day became night. And this change of the day Thales, the Milesian, had foretold to the Ionians, laying down as a limit this very year in which the change took place. The Lydians, however, and the Medes, when they saw that it had become night instead of day, ceased from their fighting and were much more eager, both of them, that peace should be made between them." Henry Smith Williams The Beginnings of Greek Science Thales of Miletus gained great fame by predicting an eclipse of the sun of 25th May 585 BC. Today this seems unlikely as the Astronomy as we assume at that time was not developed to be accurate enough to predict such phenomena. Some say that he was just lucky since the Chaldeans told him that every 90 years there is a eclipse of the sun but solar eclipses occur only in narrow regions on earth, unlike lunar eclipses that are visible everywhere.

Aristarchus Aristarchus of Samos (c. 310-230 BC), Greek astronomer, first to maintain that the Earth rotates and revolves around the Sun. On this ground, Cleanthes the Stoic declared that he ought to be indicted for impiety. Aristarchus' advanced ideas on the movement of the Earth are known from Archimedes and Plutarch; his only extant work is a short treatise, "On the Sizes and Distances of the Sun and Moon." The values he obtained, by using geometry, are inaccurate, because of faulty observations. Aristarchus found a more precise value for the length of the solar year. A lunar crater is named for him; a peak in its centre is the brightest formation on the Moon.
