Clitorio quicunque sitim de fonte levarit Vina fugit. _Metam. Lib._ XV.] Can we think that among the worshippers of the ferocious Mexitli, and the fierce invaders of his people, there were none with natures worthy of a better belief, and a nobler cause? Destiny had thrown together two, at least, whose spirits were but little tainted with the evil of their place and their day,--in whom, perhaps, feeling rather than reason, had set a talisman that left them incorruptible. A good heart is to man what the galvanic bar of the philosopher was to the ship's copper-sheathing. It gives this protection, at least, that, through the whole voyage of life, it preserves the integrity of the vessel. The barnacle and the remora will indeed deaden its course, but the metal remains clean and bright: the billows of the world waste their corrosive powers only on the protector. Morality itself is two-fold; it is of the head, and of the heart. The first belongs to the philosopher, the second to the poet. The one is an abstraction of reason; the other an exhortation of passion. The morality of the head is the only one that is just; but it is loveliest and best when the heart enforces its precepts. With good hearts, Juan Lerma and the princess of Mexico, moved among the corruptions of superstition, uncorrupted; and preserved to themselves, unabated and unsullied, the pure and gentle feelings, which nature had showered upon them at their birth. The moon, falling aslant upon the garden, lighted the countenances of the young Spanish exile and the orphan child of Montezuma, as they rested upon the summit of a little artificial mound, ornamented with carved stone seats and rude statuary, constructed for the purpose of overlooking the walls. The visage of the Christian was illumined by pensive smiles, and his lips breathed gently and fervently the accents that were sweetest to the ears of the Indian maiden. But did he discourse of worldly affection and passion to one so ignorant and artless? A nobler spirit animated the youth. He spoke of the faith of Christians, and laboured with more than the zeal, though not perhaps with the wisdom of the missionary, to impress its divine truths upon the mind of his hearer. If his arguments were somewhat less cogent and logical than might have been spoken, it must be remembered that his religion was like that which will perhaps belong to the majority of Christians to the end of the world,--a faith of the heart, which the head has not been accustomed to canvass. He directed her eyes to the moon, to the evening star, and to those other celestial wanderers, by which the heart of man was 'secretly enticed,' even before the days of the perfect man of Uz.
