The Rosetta Stone is an Egyptian stone in granodiorite, which contains an inscription divided into registers, in three different graphs: hieroglyphic, demotic and Greek.

Since it is almost the same text, the stone offered, thanks to the Greek part, a decisive key to the understanding of hieroglyphs. The text refers to all the benefits that the country has made from the Pharaoh, the taxes he abolished, the consequent decision of the clergy to erect a statue in his honor in all the temples of the country, gold statues to be placed next to those of gods and to engage in numerous festivals in honor of the Pharaohs. It also states that the decree is published in the writing of the “words of the gods” (hieroglyphics), in the writing of the people (demotic) and in Greek. The Rosetta Stone was initially classified as “a black granite stone with three inscriptions. For a time, after his arrival in London, inscriptions on the stone were colored in white chalk to make them more readable, and the remaining surface was covered with a layer of carnauba wax designed to protect the Stone from the fingers of the visitors. This cover gave a dark color to the stone that in the identification was exchanged as black basalt. These repairs were removed when the stone was cleaned in 1999, revealing the original dark gray tint of the rock, the glitter of its crystalline structure, and a pink vein that crosses the upper left corner. Rosetta Stone is, in fact, the fragment of a larger stone. The numerous searches of the other pieces, made at Rosetta’s site, did not give a positive result and because of its state, none of the three texts is complete. The story of the stone is tied to Napoleon Bonaparte and the Egyptian country designed to strike British dominance in the Mediterranean Sea and open the way to the Indies. The Greek text on the Stone of Rosetta provided the starting point since ancient Greece was known to scholars, while the details were not known in their use during the Hellenistic period, although it was the official language of the Ptolemaic Government. At the time of stone discovery, Swedish diplomat and scholar Johan David Åkerblad was working on some little-known writings, some of which had recently been found in Egypt and which had been recognized for being demoted. The word “Rosetta Stone” is idiomatically used to represent a key to the decoding process of coded information, especially when a small but representative sample is recognized as the key to understanding a larger one.
