Spanish favorites

One of my favorite DC-area poet-people is Yvette Neisser Moreno -- who, besides giving us her own work, is active in translation of  Spanish-language poetry into English, most recently (with Patricia Bejarano Fisher) a Spanish and English edition of Venezuelan poet Maria Teresa Ogliastri’s South Pole/Polo Sur  (Settlement House, 2011).  Although I have not found any mathematical poems by Moreno, I learned from an interview that the Chilean Nobelist Pablo Neruda (1904-1973) is her favorite poet and I therefore present here the geometrically vivid opening opening stanza of Part XI of Neruda's well-known long poem, The Heights of Macchu Pichu: A Bilingual Edition (The Noonday Press, 1966).
