The Temple of the Olympian Zeus (Olympieion, Tempio di Giove Olimpico) is today an enormous mass of shattered stone blocks and pillars which an earthquake has scattered over an area of 6,000sq.m/6,800sq.yd. It is difficult without plans or the suggested reconstruction supplied by the Archeological Museum to form a picture of the building in its original state, which in its measurements apparently surpassed any other temple.
The tyrant Theron had the Olympieion designed to commemorate his victory over Carthage in the Battle of Himera in 480 B.C. It is a building of which it is only possible to talk in superlatives, for it is the largest of all Doric temples (it was even supposed to have surpassed the Temple G of Selinunte), and "it is the most original, but also the most unfathomable creation of the Greek world" (G. Gruben).
The foundations occupy a rectangle of 56.30m/185ft by 113.45m/372ft (ratio 1:2), on which rests the stylobate (52.74m/173ft by 110.10m/361ft) which supports seven columns on each of the narrow sides and 14 on the longer sides. These columns had an (estimated) height of about 18.20m/60ft and a correspondingly large base diameter of 4.05m/13ft. Goethe noted during his Italian journey of 1787: "It will give you an idea of the size of the fluting on the columns if I tell you that when I was standing there, I only managed to occupy the space of the fluting, which was like a small niche, by pressing outwards with both shoulders. It would take twenty-two men, standing next to one another in a circle, to form the circumference of one of these columns." Regarding what is "original" and "unfathomable" about the building, it departs completely from what is the norm of a Greek temple. The spaces between the columns were walled in, something which can still be deduced from remains of the southern longer side of the temple which can be seen on the site: the fragments of the wall have half-columns jutting out on the outside, and on the inside flat pilasters. The square wall came a good halfway up the height of the column. Over this niches were inserted, in which fully three-dimensional Atlantes stood. These gigantic figures were 7.65m/25ft high (one of them is to be found in the Archeological Museum, a copy stands on the temple site) and the number of them has been put at 38. They supported the entablature with pediments, the reliefs of which must have reached a height of 6m/19.5ft; according to Diodor, they dealt with the battle of the gods with the giants (on the east side) and the conquest of Troy (on the west side). The total height of the temple is estimated at approximately 40m/131ft. The walling-up of the intercolumns had the effect that there was no well-lit passage round the cella and the whole building was like one large enclosed room. There was no normal entrance in the middle of the shorter east side, because a pillar stood at this point. Instead there were entrances in the corners of this shorter side and also in the middle of the longer south side. Two rows of pillars divided the interior area into three aisles of more or less equal width. In addition there were walls between these, although possibly only up to halfway, enabling them "to let the vast area be flooded with light" (Gruben). How this enormous space was lit is not clear; E. Langlotz thinks of it as a hypaethral temple with a large roof opening. H. Drerup has pointed out that a room with pillars like this one can be considered a Phoenician-Carthaginian type of building. The gigantic Temple of Zeus, a testimony to the feelings of triumph of its creator Theron after his victory over Carthage and to the unbroken trust in the inexhaustible possibilities that Sicily offered at this time, did in fact exceed the limits of man's powers; it was left unfinished when the Carthaginians conquered Akrágas in retaliation, and remained a mere torso. It was also hit by earthquakes and for many years its ruins served as a quarry when the port of Porto Empédocle was being extended in the 18th century.
