Arcadia

a district of the Peloponnesus which, according to Virgil, was the home of pastoral simplicity & happiness. The Arcadians were, however, considered the least intellectual of all the Greeks; hence Arcadian came to have a derogatory meaning. The name Arcadia was taken by Sir Philip Sidney as the title of his famous pastoral romance (1590) and was soon generally adopted in English with much the old Virgilian significance. The famous painting "Shepherds in Arcadia" by Nicholas Poussin shows a group standing around a shepherd's tomb on which are the now familiar words: "Et in Arcadia Ego" ("We, too, once lived in Arcadia").
"Our understanding of the modern city is positioned between an urban reading and a generalized conception of the "natural," a utopian, Edenic, or arcadian possibility located within, outside of, or in an undeveloped zone of the city."
