The Bronze Age civilization of Crete, a name coined by Sir Arthur Evans derived from the legendary ruler of Knossos, Minos. The civilization is divided into three phases: Early (c 3000-2000 BC), Middle (c 2000-1550 BC), and Late (c 1550-1050 BC). Each had three subdivisions marked with Roman numerals. They stand out as the first civilized Europeans, with a highly sophisticated way of life and material equipment, and were surprisingly modern. They probably represented a fusion between Anatolian immigrants and the native Neolithic population, with some trading contacts through the east Mediterranean. In the Middle Minoan period, urbanization became apparent, towns appeared and, a Minoan specialty, the first of the great palaces, Knossos, Mallia, and Phaestos. Overseas trade was greatly expanded, too. The height of its development was in the 18th-15th centuries BC. By about 1580 BC Minoan civilization began to spread across the Aegean to neighboring islands and to the mainland of Greece. Minoan cultural influence was reflected in the Mycenean culture of the mainland, which began to spread throughout the Aegean about 1500 BC. The palaces were destroyed c 1450, probably by the cataclysmic eruption of Santorini/Thera - or by conquerors from the mainland. After that, Greek-speaking Mycenaeans gained control of Knossos and Crete; only Knossos was reoccupied on a significant scale. The final fall of Knossos, c 1400 BC, marked the end of Crete's period of greatness. Their Linear A script has not been deciphered, but Linear B has been successfully translated as an early form of Greek, written in a syllabary, but belongs only to the period of mainland domination, and is therefore more relevant to Mycenaeans than Minoans. Their pottery is among the most artistic of any place or time, using abstract curvilinear, floral, and marine designs. Craftsmen reached high levels of technical skill and aesthetic achievement in pottery, metal work, stonework, jewelry, and wall painting (the palaces are lavishly decorated with frescoes). Vessels, figurines, and magnificent seal stones were also carved in stone and bronze and gold objects made. There were many bull sporting events. Cult activities normally took place either in hilltop shrines, often in caves, or in small shrines within the palaces, and often involved animals, including goats and especially bulls. There is an alternative division of the Minoan civilization into Prepalatial (Early Minoan I-III), Protopalatial (Middle Minoan I-II), Neopalatial (Middle Minoan III-Late Minoan IIIA1), and Postpalatial (Late Minoan IIIA2-IIIC).
