Pausanias Description of Greece 9.2.7

[7]
  Advancing in the city itself from the altar and the image which have been made to Zeus of Freedom, you come to a hero-shrine of Plataea . The legends about her, and my own conjectures, I have already ¹ stated. There is at Plataea a temple of Hera, worth seeing for its size and for the beauty of its images. On entering you see Rhea carrying to Cronus the stone wrapped in swaddling clothes, as though it were the babe to which she had given birth. The Hera they call Full-grown; it is an upright image of huge size. Both figures are of Pentelic marble, and the artist was Praxiteles.
  Here too is another image of Hera; it is seated, and was made by Callimachus. The goddess they call the Bride for the following reason.
