Enters Blind Leaves Seeing Riddle — Daily Riddle

This might be the oldest riddle ever written down. It was pressed into a clay tablet in ancient Sumer roughly 4,500 years ago, long before the Greek philosophers, before the Roman Empire, before the Bible. And somehow, the answer still makes perfect sense today.

The World’s Oldest Riddle, Written in Clay

This riddle was found on a cuneiform clay tablet from ancient Sumer, in what is now modern Iraq, and dates to roughly 2500 BC. It is part of a collection of twenty-five Sumerian riddles first translated by scholar E.I. Gordon in 1960, making it one of the earliest known examples of a written riddle in human history. The full version of the riddle is actually longer, describing the “house” as standing on a foundation like the skies and covered with a veil like a secret box, but it’s the final two lines that have traveled across the centuries: one enters it blind, and leaves it seeing.

The “house” is an edubba, the Sumerian word for a scribal school, which translates literally as “House of Tablets.” These schools trained young scribes in the art of cuneiform, a writing system of over 600 characters pressed into wet clay with a reed stylus. Students entered as children, sometimes as young as eight, and spent up to twelve years mastering not just writing but also mathematics, literature, law, and multiple languages. The edubba was almost certainly where this riddle was composed, probably by a teacher who wanted to remind students of the value of what they were doing: walking into a house blind and leaving with the ability to see.

What’s quietly moving about this riddle is what it reveals about the people who wrote it. Sumer invented writing around 3500 BC, and within a thousand years they had already built schools, developed a curriculum, and started composing riddles about the purpose of education itself. They understood that knowledge is a kind of sight, that not knowing something is a kind of blindness, and that the act of learning is the moment your eyes open. That idea didn’t need to wait for Greek philosophy or Enlightenment thinking. It was already there, pressed into a lump of river clay in Mesopotamia, waiting for someone to read it.
