This is the first and only edition of this obscure and beautiful work on geometric theory, written by the Galician poet Rafael Dieste. The book plays a pivotal in Roberto Bolano’s novel 2666, where the character Amalfitano discovers it in his library in Mexico, despite having no memory of ever purchasing it.
Bolaño takes advantage of this absence of memory as to the book’s origins to include a beautiful reminiscence of bookstores in Barcelona where Amalfitano may have accidentally purchased it – perhaps at Laie, or La Central, Amalfitano thinks, with passing reference to the writers Pere Gimferrer, Rodrigo Rey Rosa, and Jaun Villoro. I like to think this reveals that Bolaño was a haunter of bookstores, and that perhaps this passage is a sort of tribute.
Amalfitano becomes obsessed with the book and it’s appearance, and, in an homage to an obscure Latin American readymade by Marcel Duchamp, hangs the book on a clothesline in his backyard so that the the book can be read by the wind and the strange diagrams within be exposed to the elements.
I suspect that the strange diagrams arranging the names of philosophers, which Amalfitano inscribes into the text of 2666, may have been influenced by the diagrams in Testamento Geometrico.
“And then he looked at Dieste’s book, the Testamento Geometrico, hanging impassively from the line, held there by two clothespins, and he felt the urge to take it down and wipe off the ocher dust that had begun to clung to it here and there, but he didn’t dare. . . “ [p. 196]
This book was not the poet’s only foray into geometry. I’ve also come across a much earlier work published in Buenos Aires in 1956, with the suggstive title ‘Nuevo Tratado de Paralelismo’, pictured below.
Dieste, Rafael. Testamento Geometrico. La Coruña: Ediciones de Castro, 1975. First edition. 8vo, 145  pp. [index], bound in printed French wraps. Text in Spanish.
A near fine copy, which appears to never have been hung from a clothesline.
Dieste, Rafael. Nuevo Tratado del Paralelismo. Buenos Aires: Atlantida, 1956. First edition. 12mo, 186 pp. + index. Bound in illustrated paper over boards. Text in Spanish. Illustrated with diagrams.
