In 750 B. C., the Greeks added the pteron to the first of the temples of Hera at Samos (the naos hekatrmpedon, c. 800 B. C.). The addition of the pteron brought differentiation of two aspects of spatial composition on the temple, i. e. the temple obtained the external appearance and therefore the naos became true interior space. This spatial differentiation closely correspond to the mythological spatial thinking on agriculture in Greek myth. That is, the naos is the metaphor of the underground which is the chthon, and the pteron is that of the terrestial world.
