Some Frenchman has called the theatre a book reversed. It is a happy epigram. By a similar analogy the engraving or mezzotint might be described as a reversed picture. And with still more propriety black and white reproductions may be compared to the pianoforte in the hands of a skilful artist. The pianoforte can interpret in cooler tones orchestral scores. It gives in its all-formal severity the line; the colour is only suggested. But such is the tendency of modern music toward painting that the success of a pianoforte virtuoso to-day depends upon his ability to arouse within his listeners' imagination the idea of colour—in reality, the emotional element. The engraver evokes colour by his cunning interplay of line and cross hatching; the mezzotinter by his disposition of dark masses and white spaces. Indeed, the mezzotint by reason of its warm, more sympathetic, and ductile medium has always seemed more colourful in his plates than the most laboriously executed steel engravings. In this sense the scraper beats the burin, while the etcher, especially if he be a painter, attains a more personal vision than either one of these processes. "The stone was made for the mystics," say the Pennells. The revival of lithography by contemporary artists of fame is very welcome.

Above all, the appeal of engraving, mezzotint, and etching is to the refined. It is an art of a peculiarly intimate character. Just as some prefer the exquisite tonal purity and finished performances of the Kneisel String Quartet to the blare and thunder of the Philharmonic Society; just as some enjoy in silence beautiful prose more than our crude drama, so the lovers of black and white may feel themselves a distinctive class. They have at their elbow disposed in portfolios or spaced on walls the eloquent portraiture, the world's masterpieces, marine views, and landscapes. There is no better way to study painting historically than in the cabinet of an engraving collector. Furthermore, divested of bad or mediocre paint—many famous pictures by famous names are mere cartoons, the paint peeled or peeling off—the student and amateur penetrates to the very marrow of the painter's conception, to the very skeleton of his technical methods.

PIRANESI

I

"Battlements that on their restless fronts bore stars" is a line from Wordsworth that Thomas de Quincey approvingly quotes in regard to his opium-induced "architectural dreams," and, aptly enough, immediately after a page devoted to Piranesi, the etcher, architect, and visionary. You may find this page in The Confessions of an English Opium Eater, that book of terror, beauty, mystification, and fudge (De Quincey deluded himself quite as much as his readers in this autobiography, which, like the confessions of most distinguished men, must not be taken too literally): "Many years ago," he wrote, "when I was looking over Piranesi's Antiquities of Rome, Mr. Coleridge, who was standing by, described to me a set of plates by that artist, called his Dreams, which record the scenery of his own soul during the delirium of a fever. Some of them (described only from memory of Mr. Coleridge's account) represented vast Gothic halls, on the floor of which stood all sorts of engines and machinery expressive of enormous power put forth and resistance overcome. Creeping along the sides of the walls, you perceived a staircase, and upon it, groping his way upward, was Piranesi himself. Follow the stairs a little farther and you perceive it to come to a sudden, abrupt termination, without any balustrade, and allowing no step onward to him who had reached the extremity, except into the depths below. Whatever is to become of poor Piranesi? You suppose, at least, that his labours must in some way terminate here. But raise your eyes, and behold a second flight of stairs still higher, on which again Piranesi is perceived, by this time standing on the very brink of the abyss. Again elevate your eyes, and a still more aerial flight of stairs is beheld, and again is poor Piranesi on his aspiring labours, and so on, until the unfinished stairs and Piranesi both are lost in the upper gloom of the hall."

This plate was evidently one of the Carceri set—sixteen in all—which the etcher improvised after some severe cerebral malady. What would we not give to have heard the poet of Kubla Khan describing the fantastic visions of the Venetian artist to the English opium eater! The eloquence of the prose passage we have transcribed has in it some faint echoes of Coleridge's golden rumble. That these two men appreciated the Italian is something; perhaps they saw chiefly in his work its fantastic side. There was no saner craftsman than Piranesi apart from certain of his plates; no more solid construction in a print can be shown than his various interpretations of the classic ruins of Rome, the temples at Pæstum. He was a great engraver and etcher whose passion was the antique. He deliberately withdrew from all commerce with the ideas and art of his own times. He loved architecture for architecture's sake; not as a decoration, not as a background for humanity, but as something personal. It was for him what the human face was for Rembrandt and Velasquez. That he was called the Rembrandt of Architecture is but another testimony to the impression he made upon his contemporaries, though the title is an unhappy one. Piranesi even in his own little fenced-off coign of art is not comparable to the etcher of the Hundred Guilder print, nor are there close analogies in their respective handling of darks and lights.

It might be nearer the mark to call Piranesi—though all such comparisons are thorns in the critical flesh—the Salvator Rosa of architecture, for there is much of Salvator's unbridled violence, fantasy, and genius for deforming the actual that is to be encountered in some of Piranesi's works. His was not a classic temperament. The serene, airy, sun-bathed palaces and temples which Claude introduced into his foregrounds are seldom encountered in Piranesi. A dark Gothic imagination his, Gothic and often cruel. In his etching of public buildings at Rome or elsewhere, while he is not always faultless in drawing or scrupulous in observation, such was the sincerity and passion of the man that he has left us the noblest transcriptions of these stately edifices and monuments. It is in the rhythmic expression of his personal moods that his sinister romantic imaginings are revealed, and with a detail and fulness that are positively overwhelming.

It should not be forgotten that in the eighteenth and in the early part of the nineteenth centuries Piranesi achieved widespread popularity. He was admired outside of Italy, in England, in France, and Germany. A generation that in England read Vathek and Mrs. Radcliffe, supped on the horrors of Melmoth and Frankenstein, knew E.T.W. Hoffmann and the German romantic literature, could be relied on to take up Piranesi, and for his lesser artistic side. Poe knew his work and Baudelaire; we see that for De Quincey he was a kindred spirit. The English mezzotinter John Martin must have studied him closely, also Gustave Doré.

The Carceri (1750) of Piranesi are indoor compositions, enclosed spaces in which wander aimlessly or deliriously the wraiths of damned men, not a whit less wretched nor awful than Dante's immemorial mob. Piranesi shows us cavernous abodes where appalling engines of torture fill the foreground, while above, at vertiginous heights, we barely discern perilous passageways, haunted windows peering out upon the high heavens, stone-fretted ceilings that are lost in a magic mist. By a sort of diabolic modulation the artist conducts our eye from these dizzy angles and granitic convolutions down tortuous and tumultuous staircases that seemingly wind about the axis of eternity. To traverse them would demand an eternity and the nerves of a madman. Lower barbaric devices reveal this artist's temperament. He is said to have executed the prison set "during the delirium of fever." This is of the same calibre as the clotted nonsense about Poe composing when intoxicated or Liszt playing after champagne. It is a credible anecdote for Philistines who do not realise that even the maddest caprice, whether in black and white, marble, music, or verse, must be executed in silence and cold blood. Piranesi simply gave wing to his fancy, recalling the more vivid of his nightmares—as did Coleridge, De Quincey, Poe, Baudelaire, and the rest of the drug-steeped choir. We recall one plate of Piranesi's in which a miserable devil climbs a staircase suspended over an abyss; as he mounts each step the lower one crumbles into the depths below.
