Spanish Papers

Of all the marvels, however, of this ancient, picturesque, romantic, and necromantic city, none in modern times surpass the Cave of Hercules, if we may take the account of Don Pedro de Roxas for authentic. The entrance to this cave is within the church of San Gines, situated in nearly the highest part of the city. The portal is secured by massy doors, opening within the walls of the church, but which are kept rigorously closed. The cavern extends under the city and beneath the bed of the Tagus to the distance of three leagues beyond. It is, in some places, of rare architecture, built of small stones curiously wrought, and supported by columns and arches.

In the year 1546 an account of this cavern was given to the archbishop and Cardinal Don Juan Martinez Siliceo, who, desirous of examining it, ordered the entrance to be cleaned. A number of persons, furnished with provisions, lanterns, and cords, then went in, and, having proceeded about half a league, came to a place where there was a kind of chapel or temple, having a table or altar, with several statues of bronze in niches or on pedestals.

While they were regarding this mysterious scene of ancient worship or incantation, one of the statues fell, with a noise that echoed through the cavern, and smote the hearts of the adventurers with terror. Recovering from their alarm, they proceeded onward, but were soon again dismayed by a roaring and rushing sound that increased as they advanced. It was made by a furious and turbulent stream, the dark waters of which were too deep and broad and rapid to be crossed. By this time their hearts were so chilled with awe, and their thoughts so bewildered, that they could not seek any other passage by which they might advance; so they turned back and hastened out of the cave. It was nightfall when they sallied forth, and they were so much affected by the terror they had undergone, and by the cold and damp air of the cavern, to which they were the more sensible from its being in the summer, that all of them fell sick and several of them died. Whether the archbishop was encouraged to pursue his research and gratify his curiosity, the history does not mention.

Alonzo Telles de Meneses, in his history of the world, records that not long before his time a boy of Toledo, being threatened with punishment by his master, fled and took refuge in this cave. Fancying his pursuer at his heels, he took no heed of the obscurity or coldness of the cave, but kept groping and blundering forward, until he came forth at three leagues’ distance from the city.

Another and very popular story of this cave, current among the common people, was, that in its remote recesses lay concealed a great treasure of gold, left there by the Romans. Whoever would reach this precious hoard must pass through several caves or grottoes; each having its particular terror, and all under the guardianship of a ferocious dog, who has the key of all the gates, and watches day and night. At the approach of any one, he shows his teeth, and makes a hideous growling; but no adventurer after wealth has had courage to brave a contest with this terrific cerberus.

The most intrepid candidate on record was a poor man who had lost his all, and had those grand incentives to desperate enterprise, a wife and a large family of children. Hearing the story of this cave, he determined to venture alone in search of the treasure. He accordingly entered, and wandered many hours, bewildered, about the cave. Often would he have returned, but the thoughts of his wife and children urged him on. At length he arrived near to the place where he supposed the treasure lay hidden; but here, to his dismay, he beheld the floor of the cavern strewn with human bones, doubtless the remains of adventurers like himself, who had been torn to pieces.

Losing all courage, he now turned and sought his way out of the cave. Horrors thickened upon him as he fled. He beheld direful phantoms glaring and gibbering around him, and heard the sound of pursuit in the echoes of his footsteps. He reached his home overcome with affright; several hours elapsed before he could recover speech to tell his story, and he died on the following day.

The judicious Don Pedro de Roxas holds the account of the buried treasure for fabulous, but the adventure of this unlucky man for very possible—being led on by avarice, or rather the hope of retrieving a desperate fortune. He, moreover, pronounces his dying shortly after coming forth as very probable; because the darkness of the cave, its coldness, the fright at finding the bones, the dread of meeting the imaginary dog, all joining to operate upon a man who was past the prime of his days, and enfeebled by poverty and scanty food, might easily cause his death.

Many have considered this cave as intended originally for a sally or retreat from the city in case it should be taken; an opinion rendered probable, it is thought, by its grandeur and great extent.

The learned Salazar de Mendoza, however, in his history of the grand cardinal of Spain, affirms it as an established fact, that it was first wrought out of the rock by Tubal, the son of Japhet, and grandson of Noah, and afterwards repaired and greatly augmented by Hercules the Egyptian, who made it his habitation after he had erected his pillars at the Straits of Gibraltar. Here, too, it is said, he read magic to his followers, and taught them those supernatural arts by which he accomplished his vast achievements. Others think that it was a temple dedicated to Hercules, as was the case, according to Pomponius Mela, with the great cave in the rock of Gibraltar; certain it is, that it has always borne the name of “The Cave of Hercules.”
