EUCLID, mathematician, flourishes at Alexandria.

Things equal to the same thing are equal.
If equals are added to equals, the sums are equal.
If equals are subtracted from equals, the remainders are equal.
Things that coincide with one another are equal.
The whole is greater than a part.
(See Thymaridas 375, Eudoxos 360, Salamis Tablet 300)

Given any 2 points, there is an interval that joins them.
An interval can be prolonged indefinitely.
A circle can be constructed when its center and a point on it are given.

All right angles are equal.
If a straight line falling on 2 straight lines makes the interior angles on the same side less than 2 right angles, the 2 straight lines, if protracted indefinitely, meet on that side on which the angles are less than the 2 right angles.

Writes  ELEMENTS  books 1-6 on plane geometry,  books 7-9 on theory of numbers,  book 10 on irrationals,  books 11-13 on solid geometry.
