Mr. Ottley supposes that Giulio Clovio (born 1498, died 1578) worked previous to his receipt of the instruction of Girolamo in a drier manner, in which no evidence appears of that imitation of Michael Angelesque pose in his figures, which in his subsequent production became so leading a characteristic of his style. It is in his earlier manner that Giulio is believed to have illuminated for Clement VII.[90] (1523-1534), while for his successor, Paul III. (1534-1539), he worked abundantly, and gradually acquired that which is best known as his later manner, in which he continued to labour, according to Vasari, until 1578, at the great age of eighty years. Mr. Ottley, however, recognizes his hand in MSS. which must have been at least five years later--during the Pontificate of Gregory XIII.[91] It is obviously impossible, in such an essay as the present, to dwell in detail upon the merits of so accomplished a master of his art. Fortunately we possess in this metropolis two fine specimens of his skill, both tolerably accessible--one in the Soane[92] and the other in the British Museum.[93] A third, of great splendour, is in the possession of Mr. Towneley, and a fourth, in the shape of an altar-card, attributed to him, is to be found in the Kensington Museum; and several fragments, formerly in Mr. Rogers's possession, have passed to Mr. Whitehead and to the British Museum. All of these exhibit a refinement of execution, combined with a brilliancy of colour and excellence of drawing, which has never been surpassed by any illuminator. Vasari gives a complete list and description of his principal works, and proves him to have been not less industrious than able.
