How did image later evolved into calligraphic art of writing?
Hieroglyphics or picture writing in which symbols represented a word was another form of the early stages of writing and true hieroglyphics were used only for decorative purposes. The most picturesque forms were carved by the early Egyptians on tombs, pillars, buildings, temples, palaces, and places where there was a need for record and communication arose. Later the art of writing was freed from any constraints of mechanical means or technological devices and calligraphy art of writing developed.
