Refers to the culture and style that flourished on the Greek mainland and various islands, excluding Crete, in the Late Bronze Age, from around 1600 BCE to around 1100 BCE. The style is known from pottery, sculpture, architecture, metal work, and wall paintings, and from its influence on many contemporary cultures. It is characterized by the combination of earlier Minoan and Middle Helladic motifs with new elements that were invented or are of unknown origin, including stylized plants and elaborate compositions that incorporate lively, naturalistic animals and marine life. In a narrow sense, the term is used to refer specifically to the art and culture of the ancient city of Mycenae. It is also used in reference to places where the Mycenaean language was spoken or the Linear B script has been found.
