In his book, "Post/Face," Rothenberg writes that gematria is a form of traditional Jewish numerology using "the fact that every letter of the Hebrew alphabet is also a number, & that words or phrases, the sums of whose letters are equal are at some level meaningfully connected." These coincidences serve as an entry for Rothenberg into the kinds of correspondences or constellations that have been central to modernist & post-modernist poetry experiments over the last century & a half. -- Source of annotation: Marvin or Ruth Sackner.
