Silliman is known for several seminal long poems such as Tjanting and Ketjak, and he has been involved in writing the long "new sentence" (he coined the phrase) poem The Alphabet for over twenty years. The Age of Huts, published by Roof Books in 1986, has had a quieter reputation, despite its relatively concise display of Silliman's wide formal experimentation and mastery. "2197" is the second half of the book, and anticipates, with its stock of phrases morphing and reappearing in different acrobatic poses throughout its pages, the preoccupation with dataflows, rhizomes and digital recurrence that has characterized much literature in the age of the internet.
