The book I chose talked about graphic design through the ages. The book is called Meggs’ History of Graphic Design. There were many chapters to this book, but what really interested me was the chapter of the invention of writing. The aurthor had talked about alot of different types of writing starting from the prehistoric era. I was really intrigued about petroglyphics which are carved or scratched signs or simple figures on rocks. I had never heard of petroglyphics before looking at this book. They are found throughout the world, whether its from Africa to North America, or the Islands of New Zealand they can be found throughout and are left by the prehistoric people. Many petroglyphs are pictographs, some could be symbols that is thought to represent ideas or concepts from the people of that time.
