When the art of medal-engraving was revived in Europe, the spirit we are now noticing took possession of those less perishable and more circulating vehicles. Satiric medals were almost unknown to the ancient mint, notwithstanding those of the Saturnalia, and a few which bear miserable puns on the unlucky names of some consuls. Medals illustrate history, and history reflects light on medals; but we should not place such unreserved confidence on medals as their advocates, who are warm in their favourite study. It has been asserted that medals are more authentic memorials than history itself; but a medal is not less susceptible of the bad passions than a pamphlet or an epigram. Ambition has its vanity, and engraves a dubious victory; and Flattery will practise its art, and deceive us in gold! A calumny or a fiction on metal may be more durable than on a fugitive page; and a libel has a better chance of being preserved when the artist is skilful, than simple truths when miserably executed. Medals of this class are numerous, and were the precursors of those political satires exhibited in caricature prints.[92] There is a large collection of wooden cuts about the time of Calvin, where the Romish religion is represented by the most grotesque forms which the ridicule of the early Reformers could invent. More than a thousand figures attest the exuberant satire of the designers. This work is equally rare and costly.[93] Satires of this species commenced in the freedom of the Reformation; for we find a medal of Luther in a monk's habit, satirically bearing for its reverse Catherine de Bora, the nun whom this monk married; the first step of his personal reformation! Nor can we be certain that Catherine was not more concerned in that great revolution than appears in the voluminous Lives we have of the great reformer. However, the reformers were as great sticklers for medals as the "papelins." Of Pope John VIII., an effeminate voluptuary, we have a medal with his portrait, inscribed _Pope Joan!_ and another of Innocent X., dressed as a woman holding a spindle; the reverse, his famous mistress, Donna Olympia, dressed as a Pope, with the tiara on her head, and the keys of St. Peter in her hands![94]
