Ictinus and Callicrates
Classical Athenian architects traditionally credited with the Parthenon.
Their names survive in sources including Plutarch, although scholars debate the division of roles.
The proportions and entasis of the Doric temple became standards of the later classical tradition.
Architecture and sculpture, including work associated with Phidias, belong to one program.
The dates indicate an approximate period of activity.
Their work should be understood in the larger context of the Acropolis.
