The labyrinth of our nightmares is a dark, branching trap with a monster inside, but for thousands of years the symbol was unicursal: a single path to the center and safely back out, designed so you could not get lost. This deep dive untangles that paradox, starting with the linguistic history, from Maximilian Mayer’s 1892 double-axe theory that Arthur Evans attached to the palace at Knossos, to the Linear B decipherment in the 1950s that tied the word to caverns on Mount Dikte and Mount Ida.

The episode follows Oxford geographer Nicholas Howarth’s expedition to the human-carved Gortyn caves, later used as a German ammunition dump, and Flinders Petrie’s excavation of the Egyptian labyrinth Herodotus described with three thousand rooms. It explains the strict distinction between a maze and a labyrinth, the seven-course Cretan pattern on coins and Roman mosaics, and its independent appearance among the Tohono O’odham, in ancient India, and on Russian White Sea islands as a product of convergent cognition. It then tracks the symbol’s transformation into cathedral pilgrimage paths at Chartres, Reims, and Amiens, Scandinavian troll traps called Troy towns, and finally a modern meditation tool in hospitals and prisons, Mark Wallinger’s London Underground plaques, and the fiction of Borges, Pan’s Labyrinth, and Percy Jackson.
