Stoa Poikile

The Stoa Poikile (Ancient Greek: ἡ ποικίλη στοά) or Painted Porch, originally called the Porch of Peisianax (Ancient Greek: ἡ Πεισιανάκτειος στοά), was erected during the 5th century BC and was located on the north side of the Ancient Agora of Athens. The Stoa Poikile was one of the most famous sites in ancient Athens, owing its fame to the paintings and loot from wars displayed in it. The Stoa was the location from which Zeno of Citium taught Stoicism. The philosophical school of Stoicism takes its name from having first been expounded here, and was derived from the Greek word stoa. Zeno taught and lectured to his followers from this porch. Excavations carried out by the American School of Classical Studies at Athens over the past two decades have revealed much of the foundations and some lower elements of the stoa on the north side of the Athenian Agora; it had a Doric columnar facade and an Ionic interior colonnade.

The Stoa Poikile was decorated by fresco painter and sculptor Micon of Athens in collaboration with Polygnotos of Thasos; both artists worked around the mid-5th century BC. The paintings were most probably hung on the inner wall of the stoa. In the time of Pausanias (2nd century AD), the paintings in the Stoa included:

There is a contrast between the mythical and historical events portrayed: depictions of Theseus' victory over the Amazonians and the Fall of Troy are juxtaposed sharply with the portrayal of the historic Battle of Oenoe (conjectured to have occurred in the pentecontaetia at Oenoe, Attica on the Thriasian Plain near Eleutherae), the first important Athenian victory over Sparta, and the Battle of Marathon. The Battle of Marathon features most predominantly and as such, displays the confidence and identity of the Athenians in the wake of the Persian Wars, particularly when compared to the two great mythical victories identified above.
