Minoan civilization activity (in the Cyclades and the Argolid/Attica). Archaeologist Olga Krzyszkowska agreed: "The stark fact is that for the prehistoric Aegean we have no direct evidence for war and warfare "per se"." Between 1935 and 1939, Greek archaeologist Spyridon Marinatos posited the Minoan eruption theory. An eruption on the island of Thera (present-day Santorini), about from Crete, occurred during the LM IA period (1550 - 1500 BC). One of the largest volcanic explosions in recorded history, it ejected about of material and was measured at 7 on the Volcanic Explosivity Index. The eruption devastated the nearby Minoan settlement at Akrotiri on
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
