The most famous clock in Spanish poetry.
“La cogida y la muerte” opens the Llanto por Ignacio Sánchez Mejías (1935), Federico García Lorca’s elegy for his bullfighter friend, gored to death in the ring. Its engine is one tolling refrain, “a las cinco de la tarde”, returning after every line until the hour of the goring fills the entire world and every clock strikes it at once.
Repetition as grief: the poem doesn’t describe mourning, it performs it.
