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_.
