at the rear of the naos. Behind the adyton, separated from it by a wall, was the opisthodomos in antis. A Doric frieze at the top of the walls of the naos consisted of metopes depicting people, with the heads and naked parts of the women made of Parian marble and the rest from local stone. Four metopes are preserved: Heracles killing the Amazon Antiope, the marriage of Hera and Zeus, Actaeon being torn apart by Artemis’ hunting dogs, Athena killing the giant Enceladus, and another more fragmentary one perhaps depicting Apollo and Daphne. All of them are kept in the Museo Archeologico di Palermo. Recent sondages performed inside the temple and under Temple E have revealed that it was preceded by two other sacred buildings, one of which was destroyed in 510 BC. Temple E was dedicated to Hera as shown by the inscription on a votive stela but some scholars deduce that it must have been dedicated to Aphrodite on the basis of structural parallels. Temple F, the oldest and smallest of the three, was built between 550 and 540 BC on the model of Temple C. Of the temples it has been the most severely spoliated. Its peristyle was 24.43 x 61.83 metres on a 6 x 14 column pattern (each 9.11 metres high), with stone screens (4.7 metres high) in the space between the columns, with false doors painted in with pilasters and architraves – the actual entrance was at the east end. It is not clear what the purpose of these screens, which are unique among Greek temples, was. Some think they were intended to protect votive gifts or to prevent particular rites (Dionysian Mysteries?) being seen by the uninitiated. Inside, there is a portico containing a second row of columns, a pronaos, a naos, and an adyton in single long, narrow structure (an archaic characteristic). On the east side, two late archaic metopes (dated to 500 BC) were found in excavations in 1823, which depict Athena and Dionysus in the process of killing two giants. Today they are kept in the Regional Archeological Museum Antonio Salinas. Scholars have suggested that Temple F was dedicated to either Athena or Dionysus. Temple G was the largest in Selinus (113.34 metres long, 54.05 metres wide and about 30 metres high) and was among the largest in the Greek world. This building, although under construction from 530 to
