 Zeno Of Sidon:     more detail

1. Euclid's Elements, Book I, Proposition 1

##### Proposition 1
To construct an equilateral triangle on a given finite straight line. Let AB be the given finite straight line. It is required to construct an equilateral triangle on the straight line AB. Describe the circle BCD with center A and radius AB. Again describe the circle ACE with center B and radius BA. Join the straight lines CA and CB from the point C at which the circles cut one another to the points A and B. Post.3 Post.1 Now, since the point A is the center of the circle CDB, therefore AC equals AB. Again, since the point B is the center of the circle CAE, therefore BC equals BA. I.Def.15 But AC was proved equal to AB, therefore each of the straight lines AC and BC equals AB. And things which equal the same thing also equal one another, therefore AC also equals BC. C.N.1 Therefore the three straight lines AC, AB, and BC equal one another. Therefore the triangle ABC is equilateral, and it has been constructed on the given finite straight line AB. I.Def.20 Q.E.F. This proposition is a very pleasant choice for the first proposition in the Elements.

Zeno of Sidon was born in the city of Sidon on the Mediterranean coast of what today is Lebanon. Sidon was one of the oldest Phoenician cities and, from its founding in the 3 rd millennium BC, was ruled by many different peoples: Assyria, Babylonia, Persia, Alexander the Great , the Seleucids of Syria, the Ptolemys of Egypt, and the Romans. To understand the philosophy of Zeno we need to make some comments about the philosopher Epicurus who founded the Epicurean School to which Zeno later belonged. Epicurus, who lived from 341BC to 270 BC, founded his own School of philosophy based on his teachings. These teachings were designed to indicate a means of living ones life, and they aimed both to guarantee happiness and to provide a means to find it. Epicurus had no interest in science for its own sake and he was a severe critic of mathematics. On science he wrote:- If we were not troubled by our suspicions of the phenomena of the sky and about death, and also by our failure to grasp the limits of pain and desires, we should have no need of natural science.

His criticisms of mathematics were very superficial of little importance since he clearly had very little understanding of the subject. In 306 BC he founded his School in Athens in the garden of his house. Reasonably enough the School became known as The Garden.

Phoenician, what's in a name? It is not certain what the Phoenicians called themselves in their own language; it appears to have been Kena'ani (Akkadian: Kinahna), "Canaanites." In Hebrew the word kena'ani has the secondary meaning of "merchant," a term that well characterizes the Phoenicians. The Greeks gave the new appellation Phoenicians to those Canaanites who lived on the seacoast and traded with them. Phoenicia is the Greek work for "purple". The most probable reason for giving this name is the famous Tyrian purple cloth which the Phoenicians manufactured and sold to the rich of the ancient world. Ethnic Origin and Language The Phoenicians probably arrived in the Eastern Mediterranean about 3000 B.C., however, nothing is known of their original homeland. What may be the most common ethnic origin they are considered to be is Semitic; however, some studies suggest that their original homeland may have been in the Indian sub-continent long before 3000 B.C. while other studies trace their origin, according to Irish records, to suggest that they descend from a Scythian King named Phoeniusa Farsa...according to the

(Alphabetically) Next Welcome page Zeno of Sidon made deep criticisms of Euclid . For example he claimed that Euclid 's first proposition assumes that two straight lines can intersect in at most one point but Euclid does not have this as an axiom. He attacked Euclid 's proof of the equality of right angles on the grounds that it presupposes the existence of a right angle. Some have suggested that these claims give Zeno of Sidon some justification to be considered as having first considered the possibility of non-Euclidean geometry. Zeno also discussed the principle of induction. References (2 books/articles) Previous (Chronologically) Next Biographies Index
