Richard Haydocke was educated at New College, in Oxford, and practised physic at Salisbury, and afterwards in London. He published a translation of Lomazzo's Art of Painting, which was first printed in Milan, in the Italian language, 1583. Mr. Hogarth fancied he saw the fundamental principle of his Analysis of Beauty in this translation, couched in the following precept of Michael Angelo to Marco da Sienna his scholar; "That he should always make a figure pyramidal, serpent-like, and multiplied by one, two, and three." Sir Richard Baker tells us, "that one Richard Haydocke, of New College in Oxon, pretended to preach in his sleep, and was by King James discovered to be an impostor." He died in the reign of Charles I.
