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
Cypro-Minoan syllabary decipherment. Currently, the total number of signs on formal Cypro-Minoan inscriptions (approx. 2,500) compares unfavorably with the number known from the undeciphered Linear A documents (over 7,000) and the number available in Linear B when it was deciphered (approx. 30,000). Furthermore, different languages may have been represented by the same Cypro-Minoan subsystem, and without the discovery of bilingual texts or many more texts in each subsystem, decipherment is extremely unlikely. According to Thomas G. Palaima, ""all" past and current schemes of decipherment of Cypro-Minoan are improbable". Silvia Ferrara also believes this to be the case, as she concluded in her
