паводле Вільгельмам Дзёрпфельдам: «Dörpfeld's new study added something novel as well: the distinction between two phases of the construction history of the Pre-Parthenon. In the older phase (Parthenon I or Pa I), perhaps at the time of Kleisthenes (Κλεισθένης), the temple was, or rather was meant to be made of sandstone. In the more recent phase (Parthenon II or Pa II), after the battle of Marathon, the unfinished work was continued in marble (on this new distinction, Dörpfeld calls the Periclean Parthenon as Pa III).» Manolis Korres. Parthenon I, Parthenon II
