Bertrand’s book is one of the documents that must be studied by any historian of the grotesque who would trace the re-awakening of a spirit in art that had dozed during the eighteenth century, a spirit quite different from that of Hogarth, with which it is sometimes confounded. Bertrand’s was not the noble, the sublime conception of the grotesque that ruled the finer drawings and much of the poetry of William Blake. It was akin to that whose love of a gargoyle brought it to life and sent Quasimodo to haunt the dark and winding stairs of the towers of Notre Dame. Bertrand contrasts Rembrandt and Callot, but does not see that in the mind of the man “who consumes himself in penetrating the mysterious symbols of nature” there is the essence of the feeling for the grotesque, which, in such men as Callot, having forgotten its origins, too often becomes mere sport, shadows flung on a wall by a will-o’-the-wisp instead of by a philosopher’s lamp. But in _Gaspard de la Nuit_ this feeling is groping towards consciousness, recognising its food in the etchings alike of Rembrandt and of Callot, of Salvator and of Durer, noticing the more obvious differences between them, but as yet incapable of a more sensitive distinction. It is interesting to notice that he takes suggestions from the Breughel[2] whose wild and energetic picture made Flaubert, ten years later, set to work on _The Temptation of St. Anthony_. Bertrand’s book is made up of six series of fantasies, labelled “Flemish School,” “Old Paris,” “The Chronicles,” like the rooms in a picture-gallery. The usual form of the pieces is that of a small number of carefully balanced paragraphs, mostly single sentences, sometimes linked by refrains of movement or meaning. Some have minute prologues and epilogues. Some are like prose-ballades, finished by an _envoi_. Few cover more than two or three pages in a small book of large type. Each one is complete in itself, and built of a firm, noun-ful prose, richer in colour than in subtlety. They were written by a man to whom sustained effort was impossible, a man elusive, _fugace_, who could not settle in one place or in one mood, and perhaps found in these little scraps of goldsmithery the nearest approach to permanence and solidity in his life. He was a hunter of the moment, and these fantasies are the only trophies of his chase. Their form seems made for him and he for it, and he needed no models for the gait of his soul.
