This is Thales, one of Pythagoras's teachers. He was born in what is 

                  625-545 B.C.     now Italy in the 630 B.C. He thought that water was the basis of everything and made up all living things. He was right about this only instead of water he found out it was electrons and protons that made up every living thing. Around 585 B.C.  Thales was the first one to predict the first eclipse of the sun. The thing in mathematics that he is really well known for is being able to measure the height of one of the Egyptian pyramids. Some really interesting mathematical things he was also able to prove were: a circle is bisected by its diameter, the angles at the bases of any isosceles triangle are equal, if two straight line cut one another, the opposite angles are equal, if two triangles have two angles and a side in common, the triangles are identical.

 This is a picture of Pherekydes. It's said that very little is known about him and his life.                                                    He did however write a book about the birth of g-ds and the origin of cosmos. This is to be one of the first prose Greek literature which now is not intact completely, but some of it remains. 

 This man is Anaximander. He also has very little known about his life. He did lots of writing which didn't 

611-546 B.C.   survive till this day. We do know and have an idea of what his writings were about. They were on nature, places and showed how he importance of his work affected astronomy and geography. He believed that the earth was in the shape of a cylinder not a circle. By the looks of it he was the first human to try and draw a map of the world. On top of drawing the first map of the world he also created something called the Solar Gnomon. This was to find out the time of the day by seeing where the sun was compare to the direction. This invention we now call a compass.
