 Ancient Computing Technology

The oldest computing technology artifacts are from Africa: the  Lebombo bone (35,000 BC) and  Ishango bone (20,000 BC) and  are thought to be ancient tally sticks or perhaps a calendar.  This book, part of a series on Technology in Ancient Cultures, captures millennia of measuring and calculating tools from around the globe including Greece, the Middle East, the Americas, China, Rome and Egypt.  Included is a timeline, a glossary and a plethora of colorful photos inside plus those on the cover:  a Chinese abacus, ancient Egyptian water clock and a Babylonian clay tablet.   
Authors Michael Woods and Mary B. Wood have written over 50 books including  King Tut,  Ancient Machines and Hurricanes.
