As regards the title of the book and the arrangement of its parts, the following remarks are offered. The word _Machberoth_, or, as some people would read it _Mechabroth_, is the plural of the singular noun _machbereth_, formed of the radix ‪חַבֵּר‬, which originally means “to join” or “to put together,” so that in the present sense the noun signifies “collections.” Immanuel purposely used the plural form as the title of his book to prevent it from being confounded with a similar work composed by Alcharizi, which is entitled _Machbereth Ithiel_, where the same term appears in the singular. Immanuel's work consists, as already stated above, of twenty-eight chapters, which seem to have been written at different times, and to have then been loosely strung together. Only the second, third, and the last three chapters of the book bear a superscription to indicate the subject of which they treat. Several of these chapters were composed by the author when he was still comparatively young, and are distinguished by the same genial Epicureanism which Horace displayed when he sang:— Quid sit futurum cras fuge quaerere, et Quem Fors dierum cunque dabit lucro Appone. On the other hand, there is no doubt that the greater part of the _Machberoth_ must belong to a later period in the author's life, when he had experienced the caprices of fortune, and his troubles had disturbed the serenity of his mind. But even then his laughter does not entirely desert him. It ought, moreover, to be remembered that injustice would be done to Immanuel, if his private life and character were to be judged in the light of his writings. In these he certainly appears as an absolute libertine, and as a scoffer at religion and religious practices; but in real life he was very different. One would rather think that the _Machberoth_ were intended to serve as a mirror, in which the culpable habits of a certain class of his Jewish contemporaries were reflected. And it is for this reason that they have more than a mere literary value. They furnish the reader with a description of the moral and social condition of an important section of the Italian Jews during part of the thirteenth and fourteenth centuries, and have been referred to by our modern Jewish historians in this connexion^[92-1]. Thus, for instance, we gather from some passages occurring in the _Machberoth_ (chap. 1) that the Jewish community of Rome was at that period in a flourishing condition, that many of its members lived in large and magnificently furnished houses, and that some of them also possessed estates in the country. Further, we are told (ibid. chap. 23) that general science, philosophy, and poetry were assiduously studied and appreciated by the Jews of Rome, and that those who attained great learning among them were held in high estimation. How eager Jewish young men in Italy were in those days to increase their knowledge of books may be seen from the following incident recorded in the
