Source A: Strabo, Geography 8.3.30, on the statue of Zeus at Olympia.
'The greatest of these offerings was the statue of Zeus made of ivory by Pheidias of Athens, son of Charmides. It was so large that, although the temple is very large, the artist seems to have missed the right proportions: he made Zeus seated, but almost touching the roof with the top of his head, so that he gives the impression that if Zeus stood up he would take the roof off the temple. ... They record that when Panainos asked Pheidias what model he was going to follow for his image of Zeus, he replied that he would make it like the image Homer gave in these lines: "The son of Kronos spoke, and nodded his dark brows, and the god's immortal hair flowed down from his deathless head, and he made great Olympus shake."'
To what extent was the cult statue the most important part of a Greek temple? Use Source A as a starting point and your own knowledge.
Model answer
Source A suggests that the cult statue was the most important part of the temple. Strabo calls Pheidias' Zeus 'the greatest of these offerings', and it was so huge that if Zeus stood up 'he would take the roof off the temple'. Pheidias modelled it on Homer's image of Zeus nodding and shaking Olympus, so the statue was meant to show the god's full majesty and fill worshippers with awe.
My own knowledge supports this. A temple was the house of the god, and its main room, the naos, was built to shelter the statue. At Olympia and in the Parthenon the statue stood at the west end facing the east door, framed by two storeys of interior columns, so everything led the eye to it. The statues were made of gold and ivory and carefully looked after: Pausanias says oil was poured in front of the Zeus to protect the ivory from damp, and water was used for the Athena Parthenos.
However, the statue was not the centre of worship. Sacrifices took place at the altar outside, and at Olympia the great ash altar of Zeus was older and more important for ritual than the temple itself. Ordinary worshippers rarely went into the naos, but everyone could see the sculpture on the outside: the pediments and metopes at Olympia and the Parthenon frieze. Temples were also treasuries: the Parthenon's back room stored Athena's wealth and the funds of the Delian League. In Athens the most sacred image was not the Parthenos but the old olive-wood statue of Athena Polias, which received the new peplos at the Panathenaia, so the Parthenos was partly a display of Athenian wealth.
Overall, the cult statue was the most important part of the temple building, which existed to house it, as Strabo's account shows. But it was not the most important part of Greek worship: the altar outside was essential, and temples also served as treasuries and symbols of civic pride.
Explanation
Strabo shows the awe the statue inspired, but a strong answer distinguishes between the temple building (built around the statue) and worship (centred on the altar). Use specific details of the Zeus and the Parthenos, then weigh the altar, the external sculpture and the treasury role before reaching a clear judgement.
