Set free, by the liberality of Abraham and Isaac Pereira, from the pressure of everyday cares, Manasseh again devoted himself to his books, and turned out a succession of treatises. History, Philosophy, Theology, he attacked them all in turn, and there is, perhaps, something besides rapidity of execution which suggests an idea of manufacture in most of these works. A treatise which he published about 1650, and which attracted very wide notice, significantly illustrated his rather fatal facility for ready writing. The treatise was entitled _The Hope of Israel_, and sought to prove no less than that some aborigines in America, whose very existence was doubtful, were lineal descendants of the lost ten tribes. The Hope itself seems to have rested on no more solid foundation than a traveller’s tale of savages met with in the wilds, who included something that sounded like the עמש (Shemang[17]) in their vernacular. The story was quickly translated into several languages, but it was almost as quickly disproved, and Manasseh’s deductions from it were subsequently rather roughly criticised. Truth to say, the accumulated stores of his mind were ground down and sifted and sown broadcast in somewhat careless and indigestible masses, and their general character gives an uncomfortable impression of machine-work rather than of hand-work. And the proportion of what he wrote was as nothing compared to what he contemplated writing. Perhaps those never-written books of his would have proved the most readable; he might have shown us himself, his wise, tolerant, enthusiastic self, in them. But instead, we possess, in his shelves on shelves of published compilations of dead men’s minds, only duly labelled and catalogued selections from learned mummies. The dream of Manasseh was to compose a ‘Heroic History,’ a significant title which shadows forth the worthy record he would have delighted in compiling from Jewish annals. It is as well, perhaps, that the title is all we have of the work, for he was too good an idealist to prove a good historian. He cared too much, and he knew too much, to write a reliable or a readable history of his people. To him, as to many of us, Robert Browning’s words might be applied-- ‘So you saw yourself as you wished you were-- As you might have been, as you cannot be-- Earth here rebuked by Olympus there, And grew content in your poor degree.’[18]
