Egyptian Origins of the Celts (Video Archive), Navigation, Ancient Lost Science

Now on Spotify with Video! https://open.spotify.com/show/57DWFx0n8eUmRyAMGTnWIOWere ancient people far better at navigation, astronomy and measuring time than modern history gives them credit for?In this episode, we speak with an experienced navigator and researcher who argues that some of the most familiar symbols of the ancient world may once have been practical instruments. At the centre of the discussion is the Celtic Cross, which he believes preserves the geometry of an early navigational device capable of measuring angles, tracking celestial bodies and potentially assisting with calculations of latitude and longitude.The conversation moves from Stonehenge and the stone circles of Britain to Egyptian measuring instruments, the Great Pyramid, Viking navigation, ancient Mediterranean seafaring, the Antikythera mechanism, early maps and the astronomical knowledge embedded in religious traditions. It also considers the possibility that techniques connected with navigation, calendars and celestial observation were guarded as professional knowledge and gradually disappeared when newer technologies made them unnecessary.Along the way, the discussion challenges conventional assumptions about how ancient sailors crossed open water, how early societies understood the movements of the Sun, Moon and stars, and why astronomical symbolism appears repeatedly in monuments, churches, temples and sacred traditions across widely separated cultures.Some of the claims made in this conversation are controversial and remain outside mainstream archaeological interpretation, but they raise a provocative question: how much practical knowledge can disappear when a technology is replaced and the people who understood it are gone?
