Bach's great compositions include his "Preludes and Fugues" for the organ, works so difficult and elaborate as perhaps to be above the average comprehension, but sources of delight and instruction to all musicians; the "Matthäus Passion," for two choruses and two orchestras, one of the masterpieces in music, which was not produced till a century after it was written; the "Oratorio of the Nativity of Jesus Christ;" and a very large number of masses, anthems, cantatas, chorals, hymns, etc. These works, from their largeness and dignity of form, as also from their depth of musical science, have been to all succeeding composers an art-armoury, whence they have derived and furbished their brightest weapons. In the study of Bach's works the student finds the deepest and highest reaches in the science of music; for his mind seems to have grasped all its resources, and to have embodied them with austere purity and precision of form. As Spenser is called the poet for poets, and Laplace the mathematician for mathematicians, so Bach is the musician for musicians. While Handel may be considered a purely independent and parallel growth, it is not too much to assert that without Sebastian Bach and his matchless studies for the piano, organ, and orchestra, we could not have had the varied musical development in sonata and symphony from such masters as Haydn, Mozart, and Beethoven. Three of Sebastian Bach's sons became distinguished musicians, and to Emanuel we owe the artistic development of the sonata, which in its turn became the foundation of the symphony.

Paintings and busts of this great minstrel are scattered everywhere throughout the land. He lies in Westminster Abbey among the great poets, warriors, and statesmen, a giant memory in his noble art. A few hours after death the sculptor Roubiliac took a cast of his face, which he wrought into imperishable marble; "moulded in colossal calm," he towers above his tomb, and accepts the homage of the world benignly like a god. Exeter Hall and the Foundling Hospital in London are also adorned with marble statues of him. There are more than fifty known pictures of Handel, some of them by distinguished artists. In the best of these pictures Handel is seated in the gay costume of the period, with sword, shot-silk breeches, and coat embroidered with gold. The face is noble in its repose. Benevolence is seated about the finely-shaped mouth, and the face wears the mellow dignity of years, without weakness or austerity. There are few collectors of prints in England and America who have not a woodcut or a lithograph of him. His face and his music are alike familiar to the English-speaking world.
