African knowledge was not only passed down orally.
The notion that ancient African education was oral and not written is only a myth. In his book, “Reversing Sail: A History of the African Diaspora,” Dr. Michael Gomez, an author and professor of history and Middle Eastern and Islamic studies at New York University, declares that, from 300 B.C. to A.D. 350, the Meroë civilization had developed a writing system of its own.
Africans were literate far before Europeans.
Gomez states that while the Western perspective dates intellect and education back to the era of Socrates and Plato, the individuals of Egypt and Nubia developed “literate, urban-based, technologically advanced civilizations” centuries before the mere establishment of Rome, let alone Athens. In fact, in his book “Echoes of Ancient African Values,” Dr. Joseph Bailey, a retired orthopedic surgeon who has become an expert in the subjects of Ancient African history and African-American experiences, states that “modifications of Egyptian writing served as the basis for the ‘new’ writings developed for many Western Semitic languages — Phoenician, Hebrew, Aramaic, etc.”
