During the Persian Wars, a Tholos usually was built in the site of battles. In Salamina it did not happen. According to my thesis, an existing structure - the stylobate of the Parthenon acquires a different meaning: for metamorphosis it was (simbolically) dedicated to the dead of the decisive naval battle as Tholos. The transfer of the omphalos, that is the civil worlds barycentre, from Delos to Delphy and then to Athens, gave to the city not only richness but also political power. Athens became the centre of a territory extending from Jonia as far as Sicily. Therefore, the city needed new structure and new symbols. I believe that the stylobate of the Parthenon is the tholos of Salaminas dead: a sublime metamorphosis taking place through the passage from Callicrates Parthenon to Ictinos. Furthermore, I think that Parthenon's upper surface was secretly dedicated to Poseidon. If it is true, the Parthenon is an anadyomene temple. Here are the indications supporting my thesis: 1) in the area widespreang from Agorà to the Acropolis there are the tombs of all the Atheniens dead in battles, except Marathon and Salamina. 2) According with some verses of Edipo to Colono of Sofocles, the name given to the Parthenon: Hekatompedon or Grat Temple, may be it is a secret dedication. 3) The optical correction of Parthenon's stylobate: it is curved in both directions. 4) In the ancient iconography the overturn ship is the tomb of the heroes, like the tholos. 5) The mysterous procession of the arreforoie from the Erechteion to the Parthenon. 6) The moving of a votive ship from Agorà to the Acropolis in the Panathenaic procession. In conclusion, I point out the correlation between ships and temples, ships and the Acropolis' holiness, between places and names of Salamina and names of Acropolis.
