The Chieftain Cup was found at Ayia Triada in southern Crete. Evans suggested that one figure was a prince (holding the staff) and an officer (holding a sword and an item Evans called a ‘lustral sprinkler’). A replica was available to purchase from Gilliéron and son but it is not known how Evans acquired his copy, which he donated to the Ashmolean.
