The Tregiffian entrance grave in Cornwall contains a carved portal stone with 25 cupmarks—13 round and 12 oval shapes—possibly encoding a lunar calendar. A solar year contains roughly 12.37 lunar cycles, meaning there are typically 12-13 full moons and 12-13 new moons annually, not a fixed 13 new moons and 12 full moons. The stone was positioned above the bones of ancestors placed in the entrance grave. Death, life, moon, sun and seasons were interconnected for these ancient peoples. ⚪⚪⚪🌙🌙🌙🌙🌙🌙🌙🌙🌙🌙🌙🌙
