Anaximander believed that everything was made from an incomprehensible substance referred to as the “unlimited”. He believed that all of the opposites found in the natural world come from this substance; it can be everything. He also believed that matter forms into something from the unlimited, stays that way for a while, and then regresses back into the unlimited. To Anaximander, the unlimited is constantly in motion, and that motion causes the different things it may be to form. “Anaximander's idea of the unlimited is probably the first purely abstract concept in Western philosophy. An abstract concept can only by understood by the mind, and cannot be directly observed. Anaximander's unlimited can't be measured or described, except intellectually.” [] Anaximander's map

He also was the first to draw a map of the entire known world, and may have been the first to determine solstices and equinoxes. Also, he was a pioneer of the concept of evolution, stating animals formed from moisture, and that humans first came from fish.

He also made a map of his vision of the universe, where earth is commonly seen as a cylindrical object at the center.
