Pausanias Description of Greece 2.11.6

[6] The neighbors are chiefly servants of the god, and within the enclosure are old cypress trees. One cannot learn of what wood or metal the statue [ agalma] is, nor do they know the name of the maker, though one or two attribute it to Alexanor himself. Of the statue [ agalma] can be seen only the face, hands, and feet, for it has about it a tunic of white wool and a cloak. There is a similar statue [ agalma] of Hygieia; this, too, one cannot see easily because it is so surrounded with the locks of women, who cut them off and offer them to the goddess, and with strips of Babylonian raiment. With whichever of these a votary here is willing to make propitiations, the same instructions have been given to him, to worship this image which they are pleased to call Hygieia.
