It is a body of poems composed during the visit of the poet to Columbia University in New York in 1929 and 1930.
During his stay, the stock market crashed in October 1929, an event which profoundly affected his poetic vision.
[1] After his stay in New York, Lorca traveled to Cuba, where he wrote one of the poems included in the book Son de negros en Cuba before returning to Spain.
Due to Franco's dictatorship, it was originally released in Mexico and the United States (translated by Rolfe Humphries).
In 1929, García Lorca had left Spain to attend some conferences in the United States and Cuba.
