Praxias and Androsthenes in Wikipedia

Praxias and Androsthenes (Ancient Greek: Πραξίας, Ἀνδροσθένης), Greek sculptors, who are said by Pausanias (x. 19, 4) to have executed the pediments of the temple of Apollo at Delphi. Both were Athenians, Praxias a pupil of Calamis. The statement raises historic difficulties, as, according to the leaders of the recent French excavations at Delphi, the temple of Apollo was destroyed about 373 B.C. and rebuilt by 339 B.C., a date which seems too late for the lifetime of a pupil of Calamis. In any case no fragments of the pediments of this later temple have been found, and it has been suggested that they were removed bodily to Rome.
