The army came at length to the place mentioned by the friendly Indians, where the road forked, and one arm of it was found, as they had foretold, obstructed with large trunks of trees, and huge stones which had been strewn across it. Cortés inquired the meaning of this from the Mexican ambassadors. They said it was done by the emperor’s orders, to prevent their taking a route which, after some distance, they would find nearly impracticable for the cavalry. They acknowledged, however, that it was the most direct road; and Cortés, declaring that this was enough to decide him in favor of it, as the Spaniards made no account of obstacles, commanded the rubbish to be cleared away. Some of the timber might still be seen by the roadside, as Bernal Diaz tells us, many years after. The event left little doubt in the general’s mind of the meditated treachery of the Mexicans. But he was too politic to betray his suspicions.[231]

They were now leaving the pleasant champaign country, as the road wound up the bold sierra which separates the great plateaus of Mexico and Puebla. The air, as they ascended, became keen and piercing; and the blasts, sweeping down the frozen sides of the mountains, made the soldiers shiver in their thick harness of cotton, and benumbed the limbs of both men and horses.

They were passing between two of the highest mountains on the North American continent; Popocatepetl, “the hill that smokes,” and Iztaccihuatl, or “white woman,”[232]—a name suggested, doubtless, by the bright robe of snow spread over its broad and broken surface. A puerile superstition of the Indians regarded these celebrated mountains as gods, and Iztaccihuatl as the wife of her more formidable neighbor.[233] A tradition of a higher character described the northern volcano as the abode of the departed spirits of wicked rulers, whose fiery agonies in their prison-house caused the fearful bellowings and convulsions in times of eruption. It was the classic fable of antiquity.[234] These superstitious legends had invested the mountain with a mysterious horror, that made the natives shrink from attempting its ascent, which, indeed, was from natural causes a work of incredible difficulty.

The great volcan,[235] as Popocatepetl was called, rose to the enormous height of 17,852 feet above the level of the sea; more than 2000 feet above the “monarch of mountains,”—the highest elevation in Europe.[236] During the present century it has rarely given evidence of its volcanic origin, and “the hill that smokes” has almost forfeited its claim to the appellation. But at the time of the Conquest it was frequently in a state of activity, and raged with uncommon fury while the Spaniards were at Tlascala; an evil omen, it was thought, for the natives of Anahuac. Its head, gathered into a regular cone by the deposit of successive eruptions, wore the usual form of volcanic mountains when not disturbed by the falling in of the crater. Soaring towards the skies, with its silver sheet of everlasting snow, it was seen far and wide over the broad plains of Mexico and Puebla, the first object which the morning sun greeted in his rising, the last where his evening rays were seen to linger, shedding a glorious effulgence over its head, that contrasted strikingly with the ruinous waste of sand and lava immediately below, and the deep fringe of funereal pines that shrouded its base.

The mysterious terrors which hung over the spot, and the wild love of adventure, made some of the Spanish cavaliers desirous to attempt the ascent, which the natives declared no man could accomplish and live. Cortés encouraged them in the enterprise, willing to show the Indians that no achievement was above the dauntless daring of his followers. One of his captains, accordingly, Diego Ordaz, with nine Spaniards, and several Tlascalans, encouraged by their example, undertook the ascent. It was attended with more difficulty than had been anticipated.

The lower region was clothed with a dense forest, so thickly matted that in some places it was scarcely possible to penetrate it. It grew thinner, however, as they advanced, dwindling by degrees into a straggling, stunted vegetation, till, at the height of somewhat more than thirteen thousand feet, ¡t faded away altogether. The Indians who had held on thus far, intimidated by the strange subterraneous sounds of the volcano, even then in a state of combustion, now left them. The track opened on a black surface of glazed volcanic sand and of lava, the broken fragments of which, arrested in its boiling progress in a thousand fantastic forms, opposed continual impediments to their advance. Amidst these, one huge rock, the Pico del Fraile, a conspicuous object from below, rose to the perpendicular height of a hundred and fifty feet, compelling them to take a wide circuit. They soon came to the limits of perpetual snow, where new difficulties presented themselves, as the treacherous ice gave an imperfect footing, and a false step might precipitate them into the frozen chasms that yawned around. To increase their distress, respiration in these aerial regions became so difficult that every effort was attended with sharp pains in the head and limbs. Still they pressed on, till, drawing nearer the crater, such volumes of smoke, sparks, and cinders were belched forth from its burning entrails, and driven down the sides of the mountain, as nearly suffocated and blinded them. It was too much even for their hardy frames to endure, and, however reluctantly, they were compelled to abandon the attempt on the eve of its completion. They brought back some huge icicles,—a curious sight in these tropical regions,—as a trophy of their achievement, which, however imperfect, was sufficient to strike the minds of the natives with wonder, by showing that with the Spaniards the most appalling and mysterious perils were only as pastimes. The undertaking was eminently characteristic of the bold spirit of the cavalier of that day, who, not content with the dangers that lay in his path, seemed to court them from the mere Quixotic love of adventure. A report of the affair was transmitted to the emperor Charles the Fifth, and the family of Ordaz was allowed to commemorate the exploit by assuming a burning mountain on their escutcheon.[237]

The general was not satisfied with the result. Two years after, he sent up another party, under Francisco Montaño, a cavalier of determined resolution. The object was to obtain sulphur to assist in making gunpowder for the army. The mountain was quiet at this time, and the expedition was attended with better success. The Spaniards, five in number, climbed to the very edge of the crater, which presented an irregular ellipse at its mouth, more than a league in circumference. Its depth might be from eight hundred to a thousand feet. A lurid flame burned gloomily at the bottom, sending up a sulphurous steam, which, cooling as it rose, was precipitated on the sides of the cavity. The party cast lots, and it fell on Montaño himself, to descend in a basket into this hideous abyss, into which he was lowered by his companions to the depth of four hundred feet! This was repeated several times, till the adventurous cavalier had collected a sufficient quantity of sulphur for the wants of the army.[238] This doughty enterprise excited general admiration at the time. Cortés concludes his report of it to the emperor with the judicious reflection that it would be less inconvenient, on the whole, to import their powder from Spain.[239]

But it is time to return from our digression, which may perhaps be excused, as illustrating, in a remarkable manner, the chimerical spirit of enterprise—not inferior to that in his own romances of chivalry—which glowed in the breast of the Spanish cavalier in the sixteenth century.

The army held on its march through the intricate gorges of the sierra. The route was nearly the same as that pursued at the present day by the courier from the capital to Puebla, by the way of Mecameca.[240] It was not that usually taken by travellers from Vera Cruz, who follow the more circuitous road round the northern base of Iztaccihuatl, as less fatiguing than the other, though inferior in picturesque scenery and romantic points of view. The icy winds, that now swept down the sides of the mountains, brought with them a tempest of arrowy sleet and snow, from which the Christians suffered even more than the Tlascalans, reared from infancy among the wild solitudes of their own native hills. As night came on, their sufferings would have been intolerable, but they luckily found a shelter in the commodious stone buildings which the Mexican government had placed at stated intervals along the roads for the accommodation of the traveller and their own couriers. It little dreamed it was providing a protection for its enemies.

The troops, refreshed by a night’s rest, succeeded, early on the following day, in gaining the crest of the sierra of Ahualco, which stretches like a curtain between the two great mountains on the north and south. Their progress was now comparatively easy, and they marched forward with a buoyant step, as they felt they were treading the soil of Montezuma.
