added by archaeologs A phase between the Late Helladic and the Protogeometric periods on mainland Greece, known from its pottery found in cemeteries in Attica and from sites in central Greece and the Peloponnese. It is dated c 1050-1020 BC. Pottery was the first art to recover its standards after the Dorian invasion and the overthrow of Mycenae. Athens escaped these disasters and in the ensuing dark age became the main source of ceramic ideas. For a short time Mycenaean motifs survived on new shapes - the Submycenaean ware. It gave way to the Protogeometric (c 1020-900 BC) style by converting the decaying Mycenaean ornament into regular geometrical patterns.
