These terracotta figurines from the 3rd and 4th centuries B.C.E. are goddesses. Scholars know they are deities because they are wearing a polos. A polos is a headdress that collects the woman’s hair into a column of sorts, which prompts her hair upward and then to cascade from the top. Images of mortal women from ancient times do not show them wearing poloi (the plural of polos).
