View of sculpture from north frieze of the Parthenon in Athens, Greece of men and horses. "The traditional interpretation of the Parthenon frieze is that it depicts, in some sense, a Panathenaic procession, part of the festival of the same name celebrated each year on the occasion of Athena's birthday ... A large proportion of the frieze, i.e. all of the west and most of the north and south sides, is devoted to the cavalcade. The beginning sections depict individual horses, horsemen and marshals. On the north and south sides the riders are separated into ranks ... It is often noted that the Parthenon frieze breaks ground in depicting a historical rather than a mythological event. Yet the frieze includes divinities and probably heroes, and though accounts of the procession are incomplete, it is certain that this representation does not seek to realistically depict the event,--Perseus Digital Library.
