This article re-examines the evidence for choral marching in the Athenian theatre, which has fostered ideas on the dramatic choruses as military training for young men, ephebes. But the late lexicographical sources are not relating to the dramatic choruses of the fifth-century and are in constant conflict with our text of the plays and literary texts decribing the theatrical context; the lexicographical writings may reflect their own time or other types of choruses e.g. dithyrambic, and can therefore not be held as evidence for 1) the performance of the chorus in fifth-century Athens, 2) tragic dance as education in warfare.
