Antonio Machado

Antonio Machado is the author of “La Torre”, a 1912 poem commonly taught to Spanish students, and the inspiration for Sangre y Flores.

From Machado’s Wikipedia page:

Antonio Cipriano José María y Francisco de Santa Ana Machado y Ruiz (1875–1939), known as Antonio Machado, was a Spanish poet and one of the leading figures of the Spanish literary movement known as the Generation of ’98. His work, initially modernist, evolved towards an intimate form of symbolism with romantic traits. He gradually developed a style characterised by both an engagement with humanity on one side and an almost Taoist contemplation of existence on the other, a synthesis that according to Machado echoed the most ancient popular wisdom.
