The Caryatids are famous. We know they are young girls that carry elaborate baskets on their heads and are entrusted with holding up the porch of the Erechtheion. Their hands are missing but we suspect they used to hold something with one of them and their garment with the other, in a posture typical of Archaic korai. Their hairstyle is elaborate and their peplos goes down to their feet. They are similar but not identical, each demonstrating differences in their hair and the folds of their drapery. The differences may be due to the various craftsmen who worked on them based on two original models. All six seem to move in a procession. And yet we do not know who they are. Building accounts of the period call them korai; the name caryatids does not appear anywhere. They are one of the loveliest mysteries of the Acropolis.
