Perhaps some symbolism in the Greek letter Psi as the symbol for psychology, and the center-stalked cactus with its uplifted arms? Frank Lloyd Wright was somewhat of a psychologist in his own right, or at least quite skilled in shaping his environment and the environment of others.
Literally building an oasis in the desert, Wright hired an hydrologist to dig for wells that provided water for fountains and pools that adorn the property. Where water didn’t flow, his brain satiated itself with the eye’s intake of landscaping made to look like coral reef. Few others have connected the internal and external worlds, of self and others, as magnificently as FLW.
Astonishing to think that this is the same man who collaborated on the design of what was known as “The Wright Synagogue” as one of his last commissions, when I was a young lad in Philadelphia, adjacent to this magnificent structure in Elkins Park, PA.
