This is probably a reference to cuneiform, the writing system invented around 3500 B.C. by the ancient Sumerians. The term "cuneiform" comes from the Latin word cuneus, which means "wedge."
Hieroglyphics is a form of writing that uses signs and symbols and was used by ancient Egyptians.
They are called hieroglyphs.
Cuneiform
Hieroglyphic writing is a form of ancient writing that used pictures and symbols. The symbols and pictures varied depending on the culture but could include shapes such as circles and triangles as well as human faces, animals, and lines.
Ancient Egyptian had far more than just two writing systems: Hieratic, Hieroglyphic, Demotic and then Coptic.
The word for ancient writing symbols, like the Egyptian ones, is "hieroglyphics".
It is called Hieroglyphics the individual characters hieroglyphs. The symbols mainly stand for sounds like the Roman letters we use today. It was this discovery along with the Rosetta stone with an identical text in Greek which allowed the Frenchman Jean Francois Champolion (1790-1832) to unlock the mystery. Using his knowledge of Coptic he was able not only to deduce the meanings of the hieroglyphs but work out the structure of Ancient Egyptian grammar.
Hieroglyphics
cuneiform is a ancient system of writing made up of triangular shapes used to create symbols, and it is historically significant because this was the first major step in the road to our present day writing, this documented life in Sumerian times (such as the book The Epic of Gilgamesh),and led to the Phonecians creating the first "letters".
The correct spelling of the term for ancient writing symbols is hieroglyphics.
The Pictographic writing used in Ancient Egypt is known as Hieroglyphics. They were used for religious purposes.
Hieroglyphics were the Ancient Egyptian's system of writing, like we have the alphabet, so a Pharaoh wouldn't have had a problem writing in hieroglyphics, as these were the symbols that the Ancient Egyptians had learnt to write with.
