An Eyre or Iter was the name of a circuit traveled by an itinerant justice in medieval England, or the circuit court he presided over [1], or the right of the king (or justices acting in his name) to visit and inspect the holdings of any vassal. The eyre involved visits and inspections at irregular intervals of the houses of all vassals in the kingdom, and often provoked terror in the populace; the 1233 Eyre of Cornwall, for example, caused most of the population to flee into the woods.[2]
