'No sooner,' said Solon, 'had he got into the library, the like of which, I may safely affirm, he had never seen before, for his raiment betokened a poor and ragged life, than he stood, and gazed as much at his ease as if it had been his own, and then, by Hercules! unbuttoning his pack, for he was burdened with one both before and behind, he threw his old limbs upon a couch, and began to survey the room! I could not but ask him, If he were the elder Piso, old Cneius Piso, come back from Persia, in Persian beard and gown?--'Old man,' said he, 'your brain is turned with many books, and the narrow life you lead here, shut out from the living world of man. One man is worth all the books ever writ, save those of Moses. Go out into the streets and read him, and your senses will come again. Cneius Piso! Take you me for a spirit? I am Isaac the Jew, citizen of the world, and dealer in more rarities and valuables than you ever saw or dreamed of. Shall I open my parcels for thee?' No, said I, I would not take thy poor gewgaws for a gift. One worm-eaten book is worth them all.--'God restore thy reason!' said he, 'and give thee wisdom before thou diest; and that, by thy wrinkles and hairless pate must be soon.' What more of false he would have added I know not, for at that moment he sprang from where he sat like one suddenly mad, exclaiming, 'Holy Abraham! what do my eyes behold, or do they lie? Surely that is Moses! Never was he on Sinai, if his image be not here! Happy Piso! and happy Isaac to be the instrument of such grace! Who could have thought it? And yet many a time, in my dreams, have I beheld him, with a beard like mine, his hat on his head, his staff in his hand, as if standing at the table of the Passover, the princess with him, and--dreams will do such things--a brood of little chickens at their side. And now--save the last--it is all come to pass. And here, too, who may this be? who, but Aaron, the younger and milder! He was the speaker, and lo! his hand is stretched out! And this young Joseph is at his knee the better to interpret his character to the beholder. Moses and Aaron in the chief room of a Roman senator, and he, a Piso! Now, Isaac, thou mayest tie on thy pack, and take thy leave with a merry heart, for God, if never before, now accepteth thy works.' And much more, noble sir, in the same raving way, which was more dark to my understanding than the darkest pages of Aristotle.' I gathered from Solon, that he would return in the evening in the hope to see me, for he had that to impart which concerned nearly my welfare. I was watching with Julia, from the portico which fronts the Esquiline and overlooks the city, the last rays of the declining sun, as they gilded the roofs and domes of the vast sea of building before us, lingering last upon, and turning to gold the brazen statues of Antonine and of Trajan, when Milo approached us, saying that Isaac had returned. He was in a moment more with us.
