Rosetta Stone Umbrella
The Rosetta Stone was discovered in 1799 by French soldiers in the village of el-Rashid(Rosetta), by the River Nile, By this time all knowledge of the ancient Egyptian scripts had been lost for over 1000 years.
The known Greek section at the bottom of the stone helped scholars decipher the two ancient Egyptian scripts - the middle one written in cursive demotic script and the top version in heiroglyphs. The text contains a decree in 196 BC establishing a cult in the temples in honour of the new King Ptolemy V Epiphanes, King of all Egypt.
The grey granitoid stone weighs 762kg. It is incomplete and was probable originally some 50cm (20in) higher, perhaps with a rounded top and carvings of the king.
