Luther, when studying, always had his dog lying at his feet--a dog he had brought from Wartburg, and of which he was very fond. An ivory crucifix stood on the table before him, and the walls of his study were stuck round with caricatures of the Pope. He worked at his desk for days together without going out; but when fatigued, and the ideas began to stagnate in his brain, he would take his flute or his guitar with him into the porch, and there execute some musical fantasy (for he was a skillful musician), when the ideas would flow upon him again as fresh as flowers after summer's rain. Music was his invariable solace at such times. Indeed Luther did not hesitate to say, that after theology, music was the first of arts. "Music," said he, "is the art of the prophets; it is the only other art, which, like theology, can calm the agitation of the soul, and put the devil to flight." Next to music, if not before it, Luther loved children and flowers. That great gnarled man had a heart as tender as a woman's. Calvin studied in his bed. Every morning at five or six o'clock, he had books, manuscripts, and papers, carried to him there, and he worked on for hours together. If he had occasion to go out, on his return he undressed and went to bed again to continue his studies. In his later years he dictated his writings to secretaries. He rarely corrected any thing. The sentences issued complete from his mouth. If he felt his facility of composition leaving him, he forthwith quitted his bed, gave up writing and composing, and went about his out-door duties for days, weeks, and months together. But so soon as he felt the inspiration fall upon him again, he went back to his bed, and his secretary set to work forthwith. Cujas, another learned man, used to study when laid all his length upon the carpet, his face toward the floor, and there he reveled amidst piles of books which accumulated about him. The learned Amyot never studied without the harpsichord beside him; and he only quitted the pen to play it. Bentham, also, was extremely fond of the piano-forte, and had one in nearly every room in his house. Richelieu amused himself in the intervals of his labor, with a squadron of cats, of whom he was very fond. He used to go to bed at eleven at night, and after sleeping three hours, rise and write, dictate or work, till from six to eight o'clock in the morning, when his daily levee was held. This worthy student displayed an extravagance equaling that of Wolsey. His annual expenditure was some four millions of francs, or about £170,000 sterling!
