It can not be without admiration the ancient Egyptian culture who left to their legacy a world in pictogram's unlike any other peoples. Many cultures originated ethnic languages with pictogram's but then moved on to script while the Egyptians did too in hieratic but continued their love affair with the hieroglyphic puzzle.
The entire ancient Egyptian world in pictures.
The head of a bull represents a bull and loaf of bread simply a loaf of bread but more than just this a pair of legs can be walking or walking backward. All living creatures, action, belief and universal existence placed into pictures.
Egyptian hieroglyphs came to its full form around 2000 bc. in Pharaonic Egypt's Middle Kingdom but never stopped being developed upon. The pictogram's could be placed into arrangements which were visually compelling and normally read from right to left even though the ancient populace loved to send their messages in many directions.
Later Egyptian scribe would make the pictogram's so complicated they could talk among themselves in the presence of foreign overlords whether Persian, Greek or Roman.
