The temple of Apollon is however impossible to skip when talking about Delphi.
The Athenian treasure house at Delphi, notice that the walls used to be incised with inscriptions covering a great deal of subjects (there is actually one paian, hymn, remaining with notes!).
Heracles (the man with the lions pelt) and Dionysus (the man who is dressed in a panthers skin and who is standing on a chariot drawn by a lion) in a Gigantomachy (fight between gods and giants). From the treasury of the Siphnians at Delphi.
[Edit 022010: please read this post on the subject, not the one below]
A battle under the walls of Troy. Here we see the dead warrior Antilochus, who's body the heroes fight about. On the Greek side we find Achilles (the man with the gorgon shield on the right side) and another Greek - the Trojans are probably represented by Hector and some other warrior, but I'm not quite sure on who and we do have good evidence for the identification. From the same building as the frieze above.
