The Mycenaean period has not yielded sculpture of any great size. The statuary of the period consists for the most part of small terracotta figurines found at almost every Mycenaean site in mainland Greece, in tombs, in settlement debris, and occasionally in cult contexts (Tiryns, Agios Konstantinos on Methana). The majority of these figurines are female and anthropomorphic or zoomorphic. The female figurines can be subdivided into three groups which were popular at different periods: the earliest are the Phi-type, which look like the Greek letter phi and their arms give the upper body of the figurine a rounded shape. The Psi-type looks like the letter Greek psi: these have outstretched upraised arms. The latest (12th century BC) are the Tau-type: these figurines look like the Greek letter tau with folded(?) arms at right angles to the body. Most figurines wear a large 'polos' hat.[ 161] They are painted with stripes or zigzags in the same manner as the contemporary pottery and presumably made by the same potters. Their purpose is uncertain, but they may have served as both votive objects and toys: some are found in children's graves but the vast majority of fragments are from domestic rubbish deposits.[ 162] The presence of many of these figurines on sites where worship took place in the Archaic and Classical periods (circa 200 below the sanctuary of Athena at Delphi, others at the temple of Aphaia on Aegina, at the sanctuary of Apollo Maleatas above Epidauros and at Amyklae near Sparta), suggests both that many were indeed religious in nature, perhaps as votives, but also that later places of worship may well have first been used in the Mycenaean period.[ 163]
