Jacques-Louis Copia, a French engraver, was born at Landau in 1764. He went to Paris, and among other plates executed a charming little portrait of Queen Marie Antoinette, after Piauger, which is very rare. He also engraved a head of Marat, terribly startling in its ghastliness, from a drawing made by David immediately after his assassination. But Copia is chiefly identified with Prud'hon, the voluptuous genius of whose works no one has more fully comprehended.

It must, however, be admitted that, apart from the great painter, Copia would have remained hidden in the crowd. His style was neither original nor brilliant, and his rare qualities of modelling and softness of execution required works suitable for their display. He died in Paris in 1799, unfortunately too early to be able to engrave the greatest works of his friend. But among other pupils he left one, Roger, who caught his manner, and is thought by many to have surpassed his master in the interpretation of the spirit of Prud'hon.
