"We wanted," he says, "to be alone, and yet to feel that there was life all around us. We went up to the flat roof of the house where, as we walked, we could look down into the crowded street, and out upon the wonderful bay, and across the bay to Ischia and Capri and Sorrento, and over the house-tops and villas and vineyards to Vesuvius. The ominous pillar of smoke hung suspended above the fatal mountain, reminding us of Pliny, its first and noblest victim. A golden vapor crowned the bold promontory of Sorrento, and we thought of Tasso. Capri was calmly sleeping, like a sea-bird upon the waters; and we seemed to hear the voice of Tacitus from across the gulf of eighteen centuries, telling us that the historian's pen is still powerful to absolve or to condemn long after the imperial sceptre has fallen from the withered hand. There, too, lay the native island of him whose daring mind conceived the fearful vengeance of the Sicilian Vespers. We did not yet know Niccolini; but his grand verses had already begun their work of regeneration in the Italian heart. Virgil's tomb was not far off. The spot consecrated by Sannazaro's ashes was near us. And over all, with a thrill like that of solemn music, fell the splendor of the Italian sunset."{13} As an illustration of this obvious fact that Longfellow, during this first European visit, while nominally training himself for purely educational work, was fitting himself also for a literary career, we find from his letter to his father, May 15, 1829, that while hearing lectures in German and studying faithfully that language, he was, as he says, "writing a book, a kind of Sketch-Book of scenes in France, Spain, and Italy." We shall presently encounter this book under the name of "Outre-Mer." He connects his two aims by saying in the same letter, "One must write and write correctly, in order to teach." Again he adds, "The further I advance, the more I see to be done. The more, too, I am persuaded of the charlatanism of literary men. For the rest, my fervent wish is to return home." His brother tells us that among his note-books of that period, we find a favorite passage from Locke which reappears many years after in one of his letters and in his impromptu address to the children of Cambridge, in 1880: "Thus the ideas as well as the children of our youth often die before us, and our minds represent to us those tombs to which we are approaching; where, though the brass and marble remain, yet the inscriptions are effaced by time, and the imagery moulders away."{14} He also included a quotation from John Lyly's "Endymion," which ten years later furnished the opening of his own "Hyperion." "Dost thou know what a poet is? Why, fool, a poet is as much as one should say--a poet." When we consider what he had just before written to his sister, it only furnishes another illustration of the fact, which needs no demonstration, that young authors do not always know themselves.
