Cryptographic, cerebral poems of spectacular virtuosity by a very young poet. One of Mr. Shapiro's favorite conceits is the pole-vaulting reach--in which the unblending essence may yet snap to with meaning at an exhilarating height. ""How wonderful to be in the arms of cerebral creatures./ You taste garage, moon, strength."" These are poems of artifacts and actualities--garages, moons and the strengths of calculated syntheses. Obscure but electric with a curiously easy music.
