Thales of Miletus

Thales of Miletus was born in 624 BC in Miletus , a Greek city in Ionia (today Turkey), the first year of the XXXV Olympiad.

Fathers

The son of de Examyas and Cleobulina, most biographers present him as a member of a distinguished family that may have had Phoenician origins.

Ionian School

Related to Anaximander , his disciple, and to Anaximenes , Anaximander’s disciple, all three being referred to as the Ionian or “Miletus” School. He is the first of the seven sages of Greece , renowned for his practical wisdom.

Astronomer

Already in his time his knowledge of astronomy was recognized after predicting the eclipse of the sun that occurred on May 28, 585 BC Diogenes Laertius said that he was the first to find out the race from one tropic to another, and the first to compare the magnitude of the sun with that of the moon, the latter manifested itself to be 720 times smaller than the former, as some write, who was the inventor of the seasons of the year and assigned three hundred and sixty-five days to it.

He is recognized for breaking with the use of mythology to explain the world and the universe, explaining nature and its phenomena through theories and hypotheses, that is, through science. He is said to have been the first to use deductive reasoning applied to geometry, as in Thales’ Theorem and also the first to whom a mathematical discovery has been attributed.

Thales theorem

It seems that he was the introducer of geometry in Greece. It is believed that he may have traveled to Egypt to receive teachings from the priests, where he was able to calculate the height of one of its pyramids after drawing a circle in the sand with a radius equal to his height and standing in the center. When the shadow touched the circumference, that is, when the length of the shadow was equal to the height, one of his assistants measured the shadow of the pyramid and in this way they were able to know its height, devising the theorem that would lead to their name: Thales’s theorem .

The Universal Sea

He was also the first in history to be interested in magnets, believing that the magnetized stone had a soul, because iron is attracted to them by magnetism. He maintained that the beginning of all things is water, from which everything comes. He believed that the Earth was a flat circular disk floating on water (the universal sea). He held the principle that everything was in living animate matter, which was driven by an internal force of transformation.

Wealth

Tired of the ridicule of his fellow citizens as they said it was strange that being so wise he was not equally rich. He got rich speculating with the oil knowing that there was going to be a good olive harvest, he rented all the presses he could find, monopolizing the market, and then rented them at the price he set and became rich in a single year. After this he sold presses and land and returned to his studies while eliminating the jokes he was subjected to.

He left no writings, and what is known about him comes from what is told in Aristotle ‘s Metaphysics . Aristotle, among others, regarded him as the first philosopher in the Greek tradition.

It is said that he married and had a son, but also that he never had them and that he adopted a nephew.

Death

Thales of Miletus died in 543 BC of sunstroke in Aydin , Anatolia, while watching some gymnastic games in the LVIII Olympiad, according to Diogenes Laertius.
