We might cover pages in enumerating the resorts of notable people in their instinctive search after necessary recreation from sterner duties. Man must be doing something in order to be happy; action being quite as necessary to the health of body and brain as thought. Schiller declared that he found the greatest happiness of life to consist in the regular discharge of some mechanical duty. "Cheerfulness," says the shrewd and practical Dr. Horne, is "the daughter of employment; and I have known a man come home from a funeral in high spirits, merely because he had the management of it." It is in our unoccupied moments that discontent creeps into the mind; busy people have no time to be very miserable. Amusements are not without a double purpose, and it is only a mistaken zeal which argues against those that are innocent. "Let the world," says that wise old philosopher Robert Burton, "have their May-games, wakes, whatsunales, their dancings and concerts; their puppet-shows, hobby horses, tabors, bagpipes, balls, barley-breaks, and whatever sports and recreations please them best, provided they be followed with discretion." Sir George Cornewall Lewis, a scholar as well as a statesman, found delight in a variety of intellectual work. He shirked as well as he could all invitations to parties, balls, and dinners, and once despairingly exclaimed, when he was called from his studies to enter into some form of amusement, "that life was tolerable were it not for its pleasures." CHAPTER V. Leonardo da Vinci, the inspired painter of the "Last Supper" upon the walls of the time-worn Milan convent,[89] is said to have had a strange inclination for dirt. One biographer tells us he grovelled in it. Da Vinci was a great engineer and scientist, as well as artist. The face of Judas in the group seated at the table carries with it a legend. The artist entertained a bitter enmity towards a priest of the Cathedral who had worked him some vital injury, either real or imaginary. His revenge was clear to him; his enemy's hated features were impressed upon his mind, and so, a little modified to suit the supposed treacherous character of the disciple, were made to constitute those of Judas at the moment when he contemplates the betrayal of his Master. The likeness was too plain not to be recognized by those who knew of the ill feeling existing between the artist and priest. The result was that the latter was virtually banished from the city, as he asked to be, and was transferred to Rome. Raphael thought he could paint best under the inspiration of wine, and therefore used it freely. Some modern critics pretend to discover the vinous influence in certain exaggerations of style peculiar to his best pictures. Notwithstanding the number and grandeur of the works which he left behind him, he died prematurely at the age of thirty-seven. A book might easily be written upon the peculiarities and habits of artists; but we continue our desultory gossip.
