In commencing an account of the life of Rembrandt Van Rhÿn and his works, I feel both a pleasure and a certain degree of confidence, as, from my first using a pencil, his pictures have been my delight and gratification, which have continued to increase through a long life of investigation. Though I cannot expect to enhance the high estimation in which Rembrandt is held by all persons competent to appreciate his extraordinary powers, nevertheless, the publication of the results of my study may tend to spread a knowledge of his principles and practice, which may be advantageous to similar branches in other schools; for, notwithstanding that his style is in the greatest degree original and peculiar to himself, yet it is founded upon those effects existing in nature which are to be discovered, more or less, in the works of all the great masters of colouring and chiaro-scuro.
