The name of this artist was Philip Roos, and he was born at Frankfort in 1655. He early showed a passion for painting, and exhibited such extraordinary talents that the Landgrave of Hesse took him under his protection, and sent him to Italy with a pension sufficient for his support. To facilitate his studies, he established himself at Tivoli (whence his name), where he kept a kind of menagerie, and on account of the number and variety of the animals, his house was called Noah's Ark.
