The Stations of the Cross
Often presented as an apostolic-era practice, it is in fact a medieval devotion that developed gradually over centuries, and its now-standard set of exactly fourteen stations was only formally fixed as late as the eighteenth century.
The fourteen-station form standardised under Pope Clement XII, 1731
Fourteen devotional images or moments tracing Jesus's path to crucifixion, walked as a ritual meditation especially during Lent.
