Though he often indulges in unmeasured self-laudation, this simple description of his moral conduct must still be credited: "I never bear my enemies malice, I remain steadfast and true to my friends, cherish gratitude towards my benefactors, have a sympathetic heart, am not ostentatious with my knowledge, and absorb myself in science and poetry, whilst my companions riot in sensual enjoyments." Immanuel belonged to those who are dominated by their wit, and cannot refrain from telling some pointed witticism, even if their dearest friends are its victims, and the holiest things are dragged in the mire by it. He allowed himself to be influenced by the vivacity of the Italians and the Europeanized Jews, and put no curb upon his tongue. What is remarkable in this satirist is that his life, his position, and occupation seem to have been in contradiction with his poetical craft. In the Roman community he filled an honorable position, was something like a president, at all events a man of distinction. He appears to have belonged to the medical profession, although he made sport of the quackery of physicians. In short, he led the domestic life of his time, a life permeated by morality and religion, giving no opportunity for excess. But his honorable life did not prevent him from singing riotous songs, and from writing as though he were unconscious of the seriousness of religion, of responsibility and learning. Immanuel was acquainted, if not on intimate terms, with the greatest poet of the Middle Ages, the first to open the gates of a new epoch, and to prognosticate the unity of Italy in poetic phrase. Probably they came to know each other on one of Dante's frequent visits to Rome, either as ambassador or exile. Although their poetic styles are as opposite as the poles--Dante's ethereal, grave, and elevated; Immanuel's forcible, gay, and light--they, nevertheless, have some points of contact. Each had absorbed the culture of the past; Dante the catholic, scholastic, and romantic elements; Immanuel the biblical, Talmudical, Maimunist, philosophical, and neo-Hebraic products. Both elaborated this many-hued material, and molded it into a new kind of poetry. The Italians at that time were full of the impulse of life, and Immanuel's muse is inspired by the witchery of spring. He wrote ably in Italian, too, of which a beautiful poem, still extant, gives evidence. Immanuel was the first to adapt Italian numbers to the neo-Hebraic lyre. He introduced the rhyme in alternate lines (Terza rima in sonnet form), by which he produced a musical cadence. His poems are not equally successful. They are wanting not in imagination, but in tenderness and grace. His power lies in poetical prose (Meliza), where he can indulge in free and witty allusions. In this style he composed a host of short novels, riddles, letters, panegyrics, and epithalamia, which, by clever turns and comic situations, extort laughter from the most serious-minded readers.
