Estimated to have been written around 300BC by Euclid, a greek mathematician, Element's is still considered to be one of the greatest mathematical works ever written.

"i. A point is that which has position but not dimensions."'
ii. A line is length without breadth.
v. A surface is that which has length and breadth
He was however not the first to discover Pythagorian theorem.

Look back at the treatsie of Euclid's Elemnents conclusion;
"CONCLUSION. In the foregoing Treatise we have given the Elementary Geometry of the Point, the Line, and the Circle, and figures formed by combinations of these. But it is important to the student to remark, that points and lines, instead of being distinct from, are limiting cases of, circles; and points and planes limiting cases of spheres. Thus, a circle whose radius diminishes to zero becomes a point"
