In this hall are displayed the most emblematic works of Delphi dating from the 4th and the 3rd century BC and attest to the major significance of the oracle during that period. The marble acanthus column (332-322 BC) is topped with three young female dancers. Their height exceeds 2m, while originally the column was around 11m high. According to a recent theory, the composition was surmounted by the marble omphalos (navel) which is displayed in the same hall.

A significant find was a sculptural group dedicated by Daochos II of Pharsalus (337 – 332 BC). Eight statues of the dedicator’s family members were originally mounted on an oblong pedestal engraved with inscriptions providing information on the identity of each man. The second statue depicts Agias, son of Acnonios, and it is believed to be a marble copy of an original bronze statue created by the infamous sculptor Lysippos.

The statue of the “Philosopher” of Delphi (ca. 270 BC), depicts an anonymous elderly man. Judging by his garments and posture, experts have presumed that it portrays a philosopher or a priest of Apollo.
