Out-of-Place Artifacts

Hammers in stone, batteries in Baghdad. Objects that shouldn't exist — but do.

'Out-of-place artifacts' is a catch-all: the Antikythera mechanism (genuine), the Baghdad battery (plausible), the London Hammer and Coso artifact (misidentified — a modern hammer in fast-forming concretion, a 1920s spark plug). The category's value is that its best members are real: objects demonstrating knowledge conventional chronology didn't predict. Connects Antikythera, the battery, and the Smithsonian-vault suppression lore.
