Oracle Playground is named for its proximity to Adelphi Street, which runs to the west of this site. The word Adelphi has great significance in classical Greek history and mythology. Although the modern Greek translation defines adelphi as “sister”, the American adaptation means “at Delphi.” Delphi was a town in ancient Greece located on the lower slopes of Mount Parnassus. Considered by the ancient Greeks to be the center of what they thought was a flat, circular earth, Delphi was home to the oracle of the earth goddess who was guarded by a serpent, Python. In mythology, Apollo slew Python and took over the oracle. The oracle was consulted on private matters, such as which suitor was best for your daughter, as well as public affairs, such as when to go to war. Replies were received in the form of ambiguous answers, or oracles, which conveyed predictions and messages that, when interpreted correctly, foretold the future.
