Nikiasfrieden
The Temple of Athena Nike was finished around 420 BC, during the Peace of Nicias. It is a "tetrastyle" (four column) Ionic structure with a colonnaded portico at both front and rear facades ("amphiprostyle"), designed by the architect Kallikrates. The columns along the east and west fronts were monolithic columns. The temple ran 8 metres (27 ft) long by 5.5 metres (18.5 ft) wide and 7 metres (23 ft) tall. The total height from the stylobate to the acme of the pediment while the temple remained intact was a modest 7 metres (23 ft). The ratio of height to diameter of the columns is 7:1, rather than the more standard 9:1 or 10:1 ratio in Ionic buildings. Constructed from white Pentelic marble, it was built in stages as war-starved funding allowed.
