Poetry. THE DIAMOND DOG, Diane Wakoski's nineteenth collection, calls into being a world where the scientific and the mytho-poetic interact and combine. Here, in her first collection of entirely new work since Argonaut Rose (Black Sparrow Press, 1998), planets move in the perturbed ellipses of warped, Einsteinian space. Yet too, in the realm of the Diamond Dog, stars still turn in their Ptolemaic spheres. Here, the air can be Linden green, Lorca green, and the stem of a carnation can be the line on an astronomer's spectrograph, the signature of oxygen in some distant star.
