Filmed on the centenary of the death of the classic of American literature, Washington Irving, 1859-1959, according to his short story.
The plot of the cartoon affects the historical period of the Reconquista - the process of liberation by the Spaniards and Portuguese of their lands on the Iberian Peninsula, captured from the 8th to the 15th centuries by Moors - Arabs and Berbers.
A very similar plot with a piece of parchment paper, a candle, a magic spell and a closed treasure cave was used in the 1972 fairy tale "Hurry while the candle burns" by Ekaterina Borisova.
