[1] He submitted it to the 1877 edition of the Exposiciones Nacionales de Bellas Artes where it received the first prize.

The director of the museum, Benito Soriano Murillo, proposed its relocation in the open space so that the public could freely enjoy this peculiar and unusual creation.

The architect Francisco Jareño was charged to design the pedestal, that is octagonal with figures of devils on each side gripping fishes, lizards and snakes, and placed at the center of a fountain of 10 meters diameter, itself surrounded by a parterre.

It is renowned for its dramatic appeal, the tension in the expression and its ambiguity in treating a polemical subject that caused turmoil regarding its possible interpretation as a satanic tribute.
