A recent discovery in Mexico reveals the characters of a writing system nearly three-thousand years ago. The discovery, a stone slab, contains 62 symbols, interpreted by archaeologists to be a written language. The writing is credited to the Olmec civilization, known best for their large head statues. The text is currently indecipherable, but archaeologists are hoping that future finds may provide clues. The findings are published in the journal Science.
