Concerning the Bronze Age of the Cyclades, Aegean Islands, equivalent to Helladic on the Greek mainland and Minoan in Crete. It is usually divided into three major divisions: Early (c 3000-2000 BC), Middle (c 2000-1550 BC), and Late (c 1550-1050 BC). In the earlier Bronze Age, Cycladic culture seems to be largely independent, but in the late Middle Cycladic to early Late Cycladic, Minoan influence becomes important. After c 1400 BC mainland (Mycenaean) influence replaces the Minoan and many islands were colonized by the Mycenaeans. Colin Renfrew has proposed an alternative Early Cycladic subdivision into Grotta-Pelos, Keros-Syros, and Phylakopi I - a culture sequence.
