2. In the set of cartoons for the tapestries of the Sistine Chapel (Kugler's Handbook, ii. 394), as originally prepared by Raphael, we have the foundation, the heaven-bestowed powers, the trials and sufferings of the early Church, exhibited in the calling of St. Peter, the conversion of St. Paul, the acts and miracles of the apostles, the martyrdom of St. Stephen; and the series closed with the Coronation of the Virgin, placed over the altar, as typical of the final triumph of the Church, the completion and fulfilment of all the promises made to man, set forth in the exaltation and union of the mortal with the immortal, when the human Mother and her divine Son are reunited and seated on the same throne. Raphael placed on one side of the celestial group, St. John the Baptist, representing sanctification through the rite of baptism; and on the other, St. Jerome, the general symbol of sanctification through faith and repentance. The cartoon of this grand symbolical composition, in which all the figures were colossal, is unhappily lost; the tapestry is missing from the Vatican collection; two old engravings, however, exist, from which some idea may be formed of the original group. (Passavant's Rafael, ii. 258.) 3. It will be interesting to remember that the earliest existing impression taken from an engraved metal plate, is a "Coronation of the Virgin." Maso Finiguerra, a skilful goldsmith and worker in niello, living at Florence in 1434, was employed to execute a pix (the small casket in which the consecrated wafer of the sacrament is deposited), and he decorated it with a representation of the Coronation in presence of saints and angels, in all about thirty figures, minutely and exquisitely engraved on the silver face. Whether Finiguerra was the first worker in niello to whom it occurred to fill up the lines cut in the silver with a black fluid, and then by laying on it a piece of damp paper, and forcibly rubbing it, take off the fac-simile of his design and try its effect before the final process,--this we can not ascertain; we only know that the impression of his "Coronation" is the earliest specimen known to exist, and gave rise to the practice of cutting designs on plates of copper (instead of silver), for the purpose of multiplying impressions of them. The pix finished by Maso in 1452 is now in the Florence Gallery in the "Salle des Bronzes." The invaluable print, first of its species, exists in the National Library at Paris. There is a very exact fac-simile of it in Otley's "History of Engraving," Christ and the Virgin are here seated together on a lofty architectural throne: her hands are crossed on her bosom, and she bends her meek veiled head to receive the crown, which her Son, who wears a triple tiara, places on her brow. The saints most conspicuous are St. John the Baptist, patron of Florence and of the church for which the pix was executed, and a female saint, I believe St. Reparata, both standing; kneeling in front are St.
