The Korai of the Acropolis of Athens are a group of female statues (Korai), discovered in the Perserschutt of the Acropolis of Athens in the last quarter of the nineteenth century, all of the same typology and clear votive function. Through them it is possible to trace the stylistic evolution of Archaic Attic sculpture for almost a century, from 570 to 480 BC. This demonstrates in particular the beginning and development of Ionian influence on Athenian art of the second half of the 6th century BC. This was the period when Ionian elements first appear in the architectural works of the Peisistratids and close connections between Ionia and Athens developed. Towards the end of the 6th century BC this influence is seen to be overcome, or rather absorbed, and a new style is born, the so-called severe style, with increasing Peloponnesian influence.
Among the most ancient korai found on the Athenian acropolis, are Acropolis 619 and Acropolis 677 which date from the first half of the 6th century and derive from Samos and Naxos respectively, while the Kore of Lyons, dating to the middle of the century, represents the first example of Ionian influence on Attic sculpture, as well as the first use of typical Ionian costume in Attica. In the same category is Acropolis 593.
The replacement of the Dorian costume with the Ionian one caused a change in the whole formal system. The hand that held out the offering is detached from the bust to extend forwards, while the arm at her side gathers her skirts, after the model seen in Ionian female figures, like the Group of Geneleos. The change was introduced some time before the Peplos Kore (Acropolis 679), around 10 or 15 years after the Kore of Lyons.
The juxtaposition of the Attic korai of the 530s BC with the Leda on the amphora of Exekias in the Museo Gregoriano Etrusco is common. This group includes the Peplos Kore and Acropolis 678, which however display entirely different temperaments from each other.Acropolis 669 seems to Payne to be a transitional figure; the kore has a body structure close to the older model, but the eyes have been reduced in size and the Nasolacrimal ducts are marked, as in all later korai. From this kore onwards, the Ionian costume assumes a standardised form based on the depth and looseness of the drapery of the himation and on the playful representation of the material. Ernst Langlotz does not considerthe combination of old and new elements sufficient justification for a higher dating and places this kore, like Acropolis 678 at the end of the century.
