#487 – Irving Finkel: Deciphering Secrets of Ancient Civilizations & Flood Myths
2025/12/12
Irving Finkel is a scholar of ancient languages and a longtime curator at the British Museum, renowned for his expertise in Mesopotamian history and cuneiform writing. He specializes in reading and interpreting cuneiform inscriptions, including tablets from Sumerian, Akkadian, Babylonian, and Assyrian contexts. He became widely known for studying a tablet with a Mesopotamian flood story that predates the biblical Noah narrative, which he presented in his book “The Ark Before Noah” and in a documentary that involved building a circular ark based on the tablet’s technical instructions.

#481 – Norman Ohler: Hitler, Nazis, Drugs, WW2, Blitzkrieg, LSD, MKUltra & CIA
2025/09/19
Norman Ohler is a historian and author of “Blitzed: Drugs in the Third Reich,” a book that investigates the role of psychoactive drugs, particularly stimulants such as methamphetamine, in the military history of World War II. It is a book that two legendary historians Ian Kershaw and Antony Beevor give very high praise for its depth of research. Norman also wrote “Tripped: Nazi Germany, the CIA, and the Dawn of the Psychedelic Age”, and he is working on a new book “Stoned Sapiens” looking at the history of human civilization through the lens of drugs.
