When the Rosetta stone was found in August of 1799 nobody knew how to read the stone. Because it said the same thing in three different languages Greek, Egyptian and Egyptian hieroglyphics. It took 20 years to read what the Rosetta stone had said. The people who wrote the words on the Rosetta stone were a group of priests they had written that the priests at a temple in Memphis supported the king. The stone is a valuable piece of history because it uncovered a lot of history about Egyptian culture and how to read and write hieroglyphics. The stone is made out of a slab granodiorite.
