Minoan chronology culture was termed Helladic and Cycladic. In 1941 Arne Furumark applied the term Mycenaean to LH and LC. As it is clear that the Mycenaean Greeks dominated at Knossos at some point in Late Minoan (LM), the latter is often included under "Mycenaean" or called "Minoan-Mycenaean". The major study of Cretan pottery was Evans'. A very general stylistic trend was from dark decoration on a light background in the Early Minoan to white and red decorations on a dark wash or slip in Middle Minoan. Finally, there was a return to the earlier manner of dark on light in Late
Minoan civilization Ancient Egypt). Evans' system divides the Minoan period into three major eras: early (EM), middle (MM) and late (LM). These eras are subdivided—for example, Early Minoan I, II and III (EMI, EMII, EMIII). Another dating system, proposed by Greek archaeologist Nicolas Platon, is based on the development of architectural complexes known as "palaces" at Knossos, Phaistos, Malia and Kato Zakros. Platon divides the Minoan period into pre-, proto-, neo- and post-palatial sub-periods. The relationship between the systems in the table includes approximate calendar dates from Warren and Hankey (1989). The Thera eruption occurred during a mature phase of the LM
