The Library of History by Diodorus the Sicilian is one of the most highly regarded universal histories in antiquities. His work includes the history of Egypt, Asia, Africa, Greece and Europe. His book is a must read for research of ancient history.
The Histories of Herodotus written in 440 BC is considered to be the founding work of history in Western literature. His history included stories and fables but he claimed to have traveled extensively and learned about many countries through direct observation.
The thesis of Stolen Legacy is that the Egyptians created what is wrongly called Greek philosophy. Dr. James argues that the African origin of Greek Philosophy is well known but rarely discussed. Ancient Greek historians such as Herodotus and Diodorus the Sicilian wrote in significant detail about the contributions of Egypt. Egyptian technology and libraries were unmatched and Greek philosophers such as Pythagoras and Plato studied there. The contribution of Africa to the intellectual foundation of modern knowledge is tremendous but unacknowledged.
