For many years Luzzatto carried on a correspondence with some of the most renowned savants of his time, such as Rapoport, Zunz, Steinschneider, the Christian professors Delitzsch, Rosenmüller, and Martinet, in addition to whom might also be mentioned Geiger, Sachs, Dukes, Jellinek, Fürst, Kirchheim, Reggio, and Ghirondi. They all profited more or less from the literary contents of his letters, which they frequently utilized in their own work. Luzzatto wrote Hebrew, Aramaic, Latin, French, and German with a certain amount of ease and fluency, but he was a master of Italian prose and verse. A renowned Italian poetess, Eugenia Pavia Gentilomo by name, thought so much of his taste that she always submitted her poems in MS. to him before she sent them to the press for publication. Though Luzzatto's general correspondence was large the bulk of it was with Rapoport and Geiger. It is a well-known fact that Geiger was greatly helped by Luzzatto in the preparation of his excellent German version of Jehuda Halevi's Hebrew poems and songs. On one occasion, when Geiger delayed in answering a long letter of Luzzatto's, the latter reminded him of his omission in a poem consisting of four stanzas, each of which was composed in another language. One stanza, written in French, is worth reproducing:— Monsieur le Grand-Rabbin, Abraham Violoniste^[157-1] Avez-vous tout d'un coup cassé le violon? Ne donne-t-elle plus votre main le doux son, L'aimable mélodie, ranimant l'esprit triste? Equally interesting is a German poem by Geiger to Luzzatto, accompanying a copy of Jehuda Halevi's works, in which he gratefully acknowledges his many obligations to Luzzatto. It runs as follows:— Aus frommer Dichter Stamm, selbst frommer Dichter, Ein Weiser, Edler, mild zugleich als Richter, Ein Nil, der überströmend Segen spendet, Doch Deines Wissensfluth nicht Schlamm aussendet. Hast meine Fluren auch getränket, Dort edle Reben eingesenket. Die Frucht ist reif, lass sie Dir reichen, Nimm sie als treuer Freundschaft Zeichen.
