So who "discovered" America? Professor, Doctor of Historical Sciences, Head of Department at the Institute of Archeology Valery Gulyaev is trying to find an answer to the question: did Christopher Columbus have predecessors? Sequentially sorting out all the candidates - the ancient Egyptians and Sumerians, the ancient Greeks and Romans, Phoenicians and Arabs, subjects of the Malian Sultan and Vikings, Chinese, Japanese, Polynesians, ten disappeared tribes of Israel and even the legendary Atlanteans, he eventually leans towards the version... And which one, you will find out by reading his fascinating book "Pre-Columbian Voyages to America."
