CATEGORY: person DEFINITION: A British scholar and archaeologist who contributed much to the study of Greek archaeology with his excavations at the Minoan palace of Knossos.
The method is based on the assumption that typologies evolved at the same rate and in the same way over a wide area or alternatively on assumptions of diffusion.
Many of the chronologies constructed before the advent of showed some of the links established by cross-dating to be invalid, so the method has become somewhat discredited.
Items having an established date, such as dated coins or buildings, or ceramics of known manufacture are most often used.
By itself, a cross-dated chronology does not give absolute dates, but it may be calibrated by reference to other dating methods.
