Forberg, good, simple man, was mistaken, owing to his too great modesty; the true feast, at once substantial, nourishing and savoury, is his own work, the work which he elaborated from his own resources, from his inexhaustible memory and from his astonishing knowledge of the Greek and Latin authors down to their minutest details. On reprinting this excellent work, which undoubtedly deserved to be translated, we have given it a new title, one that is much more suitable than the old, “The Manual of Classical Erotology.” In virtue of the charm, the abundance, the variety of the citations, it is a priceless erotic Anthology; in virtue of the methodical classification of the contents Forberg has adopted, it is a didactic work,—a veritable Manual. He began with collecting from the Greek and Latin writers the largest number possible of scattered notices, which might serve for points of comparison with the Epigrams of Beccadelli; having possessed himself of a large accumulation of these, it occurred to him to set them out in order, arranging them in conformity with the similarity of their contents, deciding finally upon a division into eight chapters, corresponding with the same number of special manifestations of the amorous fancy and its depravities: I. —Of Copulation. II. —Of Pedication. III. —Of Irrumation. IV. —Of Masturbation. V. —Of Cunnilingues. VI. —Of Tribads. VII. —Of Intercourse with Animals. VIII. —Of Spintrian Postures. He found that he had to make subdivisions in each class according to the nature of the subject, to note particularities, individualities; and the contrast between this scientific apparatus, and the facetious matters subjected to the rigorous laws of deduction and demonstration is not the least amusing feature of the book. Probably no one but a German savant could have conceived the idea of thus classifying by categories, groups, genera, variations, species and sub-species all known forms of natural and unnatural lusts, according to the most trustworthy authors. But Forberg pursued another aim besides. In the course of his researches he had noticed how reticent the annotators and expounders generally are in clearing up matters which would seem to require it the most, some in consequence of a false reserve, others for fear of appearing too knowing, and others again from ignorance; also how many mistakes and gross blunders they have fallen into, by reason of their not understanding the language of erotics and failing to grasp its infinite shades of meaning. It is precisely on those obscure and difficult passages of the Ancient poets, on those expressions purposely chosen for their ambiguity, which have been the torment of the critics and the puzzle of the most erudite commentators, that our learned Humanist has concentrated his most convincing observations.
