This symbol consists of ten dots arranged in four rows, thus forming an equilateral triangle. It is of little wonder then that the Pythagoreans came up with a triangle-based symbol in sacred geometry known as the tetractys, or the tetractys of the decad ( tetractys meaning “four”, and decad meaning “ten”). Pythagoreans celebrating the sunrise, in an 1869 painting by Fyodor Bronnikov. Nevertheless, the association of this theorem with the Pythagoreans is somewhat apt, as they seem to have been particularly interested in triangles. For instance, several Babylonian clay tablets dating to between 19 BC show some knowledge of the theorem, and is also mentioned in the Indian Shulba Sutras, written between 800 and 400 BC. Today, Pythagoras is best-known for the Pythagorean Theorem (known also as Pythagoras’ Theorem), which states that “the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle).” Although named after the Greek philosopher, the theorem is actually much older. Pythagorean Theorem: The World’s Most Beautiful Mathematical Equation A group of these thinkers were the Pythagoreans, whose school of philosophy was founded by Pythagoras of Samos. These thinkers saw symbolic and sacred meanings in geometry, and therefore their field of study may be referred to as sacred geometry. As mentioned earlier, there were other thinkers in the classical world who contributed to the study of geometry, some of whom took a different approach to this subject. elementary number theory and incommensurable lines.Įuclid’s Elements is a good example of the rational and academic approach to the study of geometry. Although commonly thought to contain only geometry, Euclid’s Elements also dealt with other areas of mathematics, i.e. This treatise is considered to be one of the most influential works in the history of mathematics. Euclid lived in Alexandria between the 4th and 3rd centuries BC, and is best-known for his Elements. Although there were many Greek and Roman thinkers who contributed to the subject, none had a greater impact than Euclid, who is often considered to be the father of geometry. It is also from the Greeks that this branch of mathematics obtained its name, as it is a combination of two Greek words, geo (earth) and metron (measure). ( Public domain )Īround the 6th century BC, the Greeks got themselves involved in geometry, transforming it from a practical subject into an abstract one based on generalizations. Elements, a fragment of which is shown here, is one of the most influential works in the history of mathematics. Nevertheless, the ancient Mesopotamians are also known to have practiced geometry, as did the ancient Chinese and Indians.Įuclid is considered the father of geometry. This is supported by written evidence from Egypt itself. According to Herodotus, geometry was established by the ancient Egyptians. Many of these, however, were crude approximations, and were based on trial and error. The earliest practitioners of geometry developed a set of rules to calculate lengths, areas, and volumes. It is commonly believed that geometry began as a practical subject, and came into being as a result of everyday concerns. Ancient Geometry: The Development of Geometry in Different Cultures The concept and application of sacred geometry can be found in many civilizations around the world. This belief may be considered to be the basis of sacred geometry. According to this view, geometry has an intuitive side to it, and that certain geometrical shapes and proportion contain sacred meaning. It has been argued, however, that there is an opposite but complementary side to this field of study. This definition fits nicely with the academic study of geometry, which is based on rationalism. The Cambridge English Dictionary defines geometry as “the area of mathematics relating to the study of space and the relationships between points, lines, curves, and surfaces”.
