The Near-Death Journey
A tunnel-of-light image appears in a Christian painting around 1500, centuries before any modern medical account. Comparative study across these older sources finds the specific CONTENT of such visions actually varies significantly by culture and era — a finding that works against the claim that they all describe one universal, culture-independent reality.
Hieronymus Bosch, Ascent of the Blessed (c. 1500); Bede's account of Drythelm's vision (c. 731)
A long literary and religious lineage of journeys to the edge of death and back, predating the modern clinical near-death experience by many centuries.
