Federico García Lorca – Flamenco song, 1921
Speleogroup reference (at very bottom of page).


DE la cueva salen
largos sollozos.

(Lo cárdeno
sobre lo rojo.)

El gitano evoca
países remotos.

(Torres altas y hombres

En la voz entrecortada

(Lo negro
sobre el rojo).

Y la cueva encalada
tiembla en el oro.

(Lo blanco
sobre lo rojo.)

From the cave
come endless sobs.

over red.)

The gypsy
recalls faraway countries.

(Tall towers
and mysterious men.)

In a faltering voice
his eyes wander.

over red.)

And the whitewashed cave
trembles in gold.
