One of the most distinguished among them was Thales of Miletus (6 4 o -543 B.C.), the founder of the Ionian school of philosophy, whose pupil, Anaximander (611-546 B.C.) is credited by Eratosthenes with having designed the first map of the world.
This period lasted' from the time of Thales, c. 600 B.C., to the capture of Alexandria by the Mahommedans, A.D.
It is probable that the algebra of the Egyptians was of a most rudimentary nature, for otherwise we should expect to find traces of it in the works of the Greek geometers, of whom Thales of Miletus (640-546 B.C.) was the first.
This conception recurs in the theory of Thales, who made water the first principle of all things.

Two Lunar Years Would Thus Contain 25 Months, Or 738 Days, While Two Solar Years, Of 3654 Days Each, Contain 7302 Days.V The `, Difference Of 72 Days Was Still Too Great To Escape Observation; It Was Accordingly Proposed By Cleostratus Of Tenedos, Who Flourished Shortly After The Time Of Thales, To Omit The Biennary Intercalation Every Eighth Year.
THALES OF MILETUS (6 40-546 B.C.), Greek physical philosopher, son of Examyus and Cleobuline, is universally recog nized as the founder of Greek geometry, astronomy and philosophy.

It is well known that this name (rocos) was given on account of practical ability; and in accordance with this we find that Thales had been occupied with civil affairs, and indeed several instances of his political sagacity have been handed down.
It is probable, however, that in the case of Thales the appellation " wise man," which was given to him and to the other six in the archonship of Damasius (586 B.C.), 1 was conferred on him not only on account of his political sagacity, but also for his scientific eminence (Plut.
74) contains two statements: - (i) the fact that the eclipse did actually take place during a battle between the Medes and the Lydians, that it was a total eclipse (Herodotus calls it a " night battle "), that it caused a cessation of hostilities and led to a lasting peace between the contending nations; (2) that Thales had foretold the eclipse to the Ionians, and fixed the year in which it actually did take place.
The second part of the statement of Herodotus - the reality of the prediction by Thales - has been frequently called in question, chiefly on the ground that, in order to predict a solar eclipse with any chance of success, one should have the command of certain astronomical facts which were not known until the 3rd century, B.C., and then merely approximately, and only employed with that object in the following century by Hipparchus.
The question, however, is not whether Thales could predict the eclipse of the sun with any chance of success - much less whether he could state beforehand at what places the eclipse would be visible, as some have erroneously supposed, and which of course would have been quite impossible for him to do, but simply whether he 1 Bretschneider (Die Geom.
In this he is followed by some other recent writers, who infer thence that the name " wise " was conferred on Thales on account of the success of his prediction.

The wonderful fame of Thales amongst the ancients must have been in great part due to this achievement, which seems, moreover, to have been one of the chief causes that excited amongst the Hellenes the love of science which ever afterwards characterized them.
Thales seems not to have left any writings behind him, though as to this there appears to be some doubt (see Diog.
Of the fact that Thales visited Egypt, and there became acquainted with geometry, there is abundant evidence.
