Its complexity was hidden in plain sight, misunderstood simply because no one expected such advanced technology to be developed in antiquity.

Rosetta Stone’s Decoding Power

When it was discovered in 1799, the Rosetta Stone appeared to be just another slab with an inscription on it. It was only later that it scholars it held the key to deciphering Egyptian hieroglyphs. The same text written in three scripts allowed linguists led by Francois Champollion to unlock an entire language that had been totally incomprehensible for centuries.
