Andreani (an-dra-a'-ne), a distinguished engraver who flourished in the 7th century. He obtained engravings worked by other hands, which he disposed of as his own. He engraved on wood in a peculiar style, known as "chiaro-oscuro," of which, however, he was not the inventor. One of his productions, "The Triumph of Julius Caesar," from Andrea Mantegna, the original of which is at Hampton Court, is cut on ten blocks of wood, and dated 1598. Andreani died at an advanced age in 1623.
