Tholos of Delphi

The Tholos of Delphi is among the ancient structures of the Sanctuary of Athena Pronaia in Delphi [1]. The circular temple, a tholos, shares the immediate site with other ancient foundations of the Temple of Athena Pronaia, all located less than a mile east of the main ruins at Delphi [1]. The architect of the "vaulted temple at Delphi" is named by Vitruvius in De architectura Book VII as Theodorus Phoceus (not Theodorus of Samos, whom Vitruvius names separately) [1]. Externally, twenty Doric columns supported a frieze with triglyphs and metopes [1]. Materials used included Eleusinian thin slabs and Pentelic marble in the superstructure and limestone at the platform [1]. In the major metopes of the outer side there are scene representations from Amazon and Centaur battles [1].
