Thales of Miletus (1) was born in Thebes in the year 625 BC and died in Athens, 547 BC, at age 78. He was a Greek philosopher, founder of the Ionian school and he was considered to be one of the Seven Sages of Greece. Mathematician, astronomer, and great thinker, Thales toured Egypt, where he conducted studies and was directly exposed to the mysteries of Egyptian spirituality/religion.
It is attributed to him the prediction of the solar eclipse in the year 585 BC, which was held an incredible feat. His mathematical talent was so unusual, it was able to establish accurately the height of the pyramids through the measuring of the shadow. Moreover, according to Herodotus, Thales of Miletus was the first mathematician to give a logical explanation for the occurrence of eclipses. Thales was the first to verify that the moon as in fact “illuminated” by the Sun, being the first one to count how many days a year was comprised of. According to Aristotle, this discovery was a landmark for the history of philosophy. Later, because his brilliant demonstrations of the geometric theorems, he was also regarded as the father of Geometry.
