The peplos was a robe renewed every four years, when it was taken by the procession of the Great Panathenaic festival and dedicated to a statue of Athena on the Acropolis. The robe was woven with scenes of a mythical battle between the gods and giants. Weaving began nine months before the Panathenaia at another festival, the Chalkeia. Two girls, appointed to serve Athena, the arrephoroi, set the warp up on the loom.
The east frieze is comprised of eight or nine blocks (research has shown that VII and VIII formed a single block) that are considerably longer than the blocks of the other sides. The middle block V is 4.50 m. in length, whereas the corner blocks are narrow because they are in fact the narrow ends of block I of the north frieze and block XLVII of the south frieze. The surviving blocks and fragments are scattered among various museums: in the Acropolis are blocks II and VI, in the British Museum blocks I, III-V, VIII and in the Louvre block VII. In addition a number of fragments are in the British Museum and others are in the Archaeological Museum of Palermo. In contrast to the west frieze, the east frieze has a certain symmetry of composition, since it is the focal point of the processions of the other sides.
The frieze of the Parthenon forms a continuous band with scenes in low relief that encircles the upper part of the cella, the main temple, within the outer colonnade. The theme represented was the procession toward the Acropolis that took place during the Great Panathenaia, the commemoration of the birthday of the goddess Athena.
