Rosetta Stone Lens Cloth
The Rosetta Stone was discovered in 1799 by French soldiers in the village of el-Rashid (Rosetta). By this time all knowledge of the ancient Egyptian scripts had been lost for over 1,000 years. The stone contains a text in three different languages and scripts. The known ancient Greek text at the bottom of the stone helped scholars decipher the ancient Egyptian scripts - the middle one written in cursive Demotic and the top version in heiroglyphs.
The grey granitoid stone weighs 762kg. It is incomplete and was probably originally some 50cm (20in) higher, perhaps with a rounded top and carvings of the king.
