making a unicorn. The Greek philosopher and scientist Anaxagoras (c. 500–c. 430 b.c.) was brought a ram with a sin- gle unicornlike horn in the center of its forehead and told that a soothsayer had claimed the single horn was a supernatural omen. Anaxagoras killed the animal, cleft its skull and showed that the brain had grown upward toward the center rather than filling both sides of the cranium, thus producing the single horn. |
